What are /r/virtualization's favorite Products & Services?

From 3.5 billion Reddit comments

It's a full-featured XenServer rebuild from source. I have no idea what the hell Citrix was thinking when they tried to make an OSS product 'crippleware' to force license buying. Incredibly ill-concieved decision.

Hello, it is not a dumb question. Here is my stupid answer: yes.

Android is an end-to-end operating system, integrated tightly to the underlying hardware. It is not made to float in a VM, or to be installed on off-the-shelf hardware.

Alas, it is possible to use it in a virtualized system, thanks to the Android x86 project, but it is not streamlined. You may to have a look at Waydroid, which follows another, and perhaps more promising approach.

Ideally, Android, or more precisely, its parent project the Android Open Source Project (AOSP), would be built against the Q35 machine model that is uses by KVM/QEMU. But it is a lot of work as Android, by default, targets the ARM architecture.

Do... Do you know what the cloud is? That is not really what we're talking about here.

https://www.android-x86.org/download Android is free.

And sure, Oracle might change the licencing. Then someone will fork it and it will continue to be free.

I'll grant that there's not really any other free type-2, windows-compatible, FOSS hypervisors around. But that's because there's four qualifiers on that sentence. Between vbox, hyper-v, vmware workstation/player, and the wide swathe of type 1s, there just isn't really a need for one. I guess add containerisation into that conversation too.

Any host-based virtualization software will work fine. I recommend VirtualBox because of its ease of use and compatibility. You just install the package, get an ISO of a linux / BSD / whatever floats your boat and insert it into the virtual drive. It'll then run through the install as by default it'll try to boot from disk.

Once installed and running all you need to do is click on the "seamless mode" button and away you go. It'll fill your screen, borderless, and it'll operate like a RDP or ICA session.

EDIT: Quick overview if you're thinking this is a garbled mess of text :P http://www.howtogeek.com/171145/use-virtualboxs-seamless-mode-or-vmwares-unity-mode-to-seamlessly-run-programs-from-a-virtual-machine/

The closest thing to what you are asking for was Citrix XenClient but that has been discontinued.

You're next best option might be QubesOS

Otherwise build a Linux hosts and use KVM, stick with Windows and use Hyper-V

Hi there :)

Disclaimer: XOA project leader here :)

If you want something working out-of-the-box: XOA Starter (cheapest edition with support and updater), and no socket/host/VM limit.

We are currently working on improving the backup stuff, we'll have reports/alerts and maybe delta VHD for the end of the year, and yes, it will be in Starter.

You also have 15 days of trial with all features if you want to make some tests for free!

edit: and if you have suggestion of features and other stuff to improve it, I'm always happy to ear it for improving the product!

i think u want a virtual private network i use wireguard to solve those problems

it has a good documenation and is well defined

https://www.wireguard.com/#learning-more

They did a thing on howtogeek where they downloaded the top 10 list from Download.com.

That might be a good start.

http://www.howtogeek.com/198622/heres-what-happens-when-you-install-the-top-10-download.com-apps/

Well its a bit complicated maybe to explain it in detail but here is my basic routine that i used to do for this setup :

• first you will need to configure your Virtualbox to have multiple networks like the following:
  • the first is NAT which i would connect it to the Mikrotik router for internet connectivity ( you can use bridged also in this case )
  • the second is host only so i can config the router from my main OS using my terminal if i wanted to ( optional)
  • the third would be internal think of it like creating a different LAN for a practicing lab where hosts will reside on this LAN subnet.
• Second step i would use a light Linux vm or several connected to the same internal network to use as a test client ( its like having a pc behind your virtual router)
• third step is fire up the Mikrotik vm and configure your interfaces properly, something like this:
  • Internet connection ==> connected to the NAT/Bridged
  • Host only ==> this is a separate interface that you can use with your main OS ( optional)
  • Internal ==> this is your virtual LAN if i may call it where your clients are connected to the router.

This is the basic setup i used to do when i couldn't have access to real hardware you can expand it as it suits your needs.

Also you should probably understand the virtual networking in virtualbox if you haven't done so you can check the link below ,its crucial to understand this and you can google Mikrotik labs you would probably find plenty.

You need to be using a different virtualization program. Q hasn't been updated since like 2008 so its broken with a lot of things.

For a free virtualization program I'd suggest Parallels Desktop Lite or VirtualBox

ESXi is a whole other operating system from VMware. You don't need that, you can do fast hypervisor virtual machines on linux, and Ubuntu is configured great for it. Look into KVM + qemu + libvirt - gets you a headless interface (virsh) to manage & run VMs. Really nice when coupled with virt-manager (a GUI) running on a linux desktop, you can connect it to your server and get what seems like a local interface for your VMs. I think there are web interfaces you can set up, too, but I never went that far.

Personally, for my limited use I found headless VirtualBox a better solution. You can set up RDP for the headless VM displays and connect to them on different ports from any old RDP client like Remmina or Windows Remote Desktop. I think you can do similar with KVM/qemu & VNC, but I found VirtualBox & RDP more reliable so far. I haven't really noticed a speed difference with VirtualBox, and it seems easier to use to me. See here. And then there's phpVirtualBox for a web interface if you like.

Yep, I think what you are looking for is something like Bochs for x86 OSes (GNU/Linux, DOS, Windows, Rhapsody), for arm OSes (Android, MacOS since 11.0) it's probably best to look into qemu (since Android is just a GNU/Linux with fancy GUI it is possible to compile qemu for it. I'm sorry I can't help more; I'm usually more interested in how to write VMs in the first place, not running them :p

If it’s under $100 USD, maybe. That’s really old. That RAM is slow. That would have been around 2010. Good news is you would get 12 cores, 24 threads, use it as a container host.

A Dell R620 with dual E5-2620v2’s and DDR3-1600 is 3 years newer. 6 core/12 thread CPU, but newer architecture by 3 years. You can find them pretty cheap. eBay, I’ve seen them for $200 USD. Throw a SATA SSD in, and they’re actually pretty decent.

Holy cow, here’s one on Amazon.

DELL PowerEdge R620 Server 2X 2.10Ghz E5-2620v2 6C 48GB 2X 300GB 10K SAS Economy (Renewed) https://www.amazon.com/dp/B07JHM3G9Z/

Here’s one on eBay. Conflict in the title and description though. One says dual 6 core, the other says E5-2697v2 12 core dual.

https://www.ebay.com/itm/284664329562?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=rcGIeBbpQFa&sssrc=2349624&ssuid=&var=&widget_ver=artemis&media=COPY

ChromeOS is only available as an x86_64 distro. Because of that it will not run on using virtualization software like Parallels or VMWare Fusion at the moment.

If you need to run ChromeOS you could try using an x86_64 emulator like QEMU. You can use the UTM (https://getutm.app/) frontend for QEMU to make things easier.

Hi,

Requirement is a bit unclear but: * You can use Xen Orchestra ACLs for that purpose. See https://xen-orchestra.com/docs/users.html#acls * But accessing a VNC console isn't really remote desktop to "work" with (check UDS Enterprise for a real Open Source virtual desktop infrastructure solution)

If it's just giving basic access to a terminal/console, ACLs are enough. If you want to prove a real virtual desktop, then go for UDS.

The easiest way to do this that I can think of would be to setup a VM with no virtual ethernet device and pass a USB (or PCIe) WIFI device to the VM. With no virtual ethernet device the VM will not be able to communicate with the host or it's connection to the intranet. VirtualBox is an open source virtualization software that this could be done with but you will need the closed source extension pack for passing the WIFI device to the VM. Otherwise, if it MUST be completely open source you could try QEMU.

You can bind NAT to a specific interface. You can also create another NAT network in VirtualBox. See https://www.virtualbox.org/manual/ch06.html#network_nat_service .

Sounds decent. I imagine you have a clean separation of data (lifeblood of any business) for regulatory, backup, and malware mitigation reasons in your architecture. Your proposal sounds like VDI.

If you have a spare computer Microsoft Hyper-V is free and Vmware ESXIis also free. Bother are commonly used in many environments.

You don't.

Virtualbox doesn't support Nested Virtualization. There has been an open feature request for it for the past 10 years (link). At this stage I doubt it will ever be added. Its one of the reasons I stopped using Virtualbox altogether.

If you wanted nested virtualization you need to either use KVM/qemu, Xen, or Vmware.

Virtualizing Linux under Windows using VirtualBox should be very much possible as suggested by /u/canadian_viking.

You will most likely suffer a drop in the performance in the virtualized Linux under Windows depending on your device specs.

Any specific help you require?

All the best!

I have a similar setup at home (been running it about five years now). 8-core AMD cpu, 32gb ram, big drives to store VM's, etc... I started out with VMWare desktop (my machines are for programming). It didn't like upgrading to the next OS version though, so I switched to Virtualbox which has a GNU license for everything as long as you're at home and only charges for the PUEL portion if you're using it for enterprise (work) stuff.

I use Lubuntu for my host OS and usually Lubuntu for my VM's (for everything from Node.js/Java/PHP) and I have some Windows 7/10 images for C#, but I don't use them much these days. It works great for me. I didn't care for Hyper-V after trying it because it locks the machine so that only Hyper-V can run and you have to change some stuff and reboot to run any other virtualization solution. I was trying it out because some of the new Docker stuff was developed for Hyper-V.

If you're talking about running servers though, you might consider going with Docker on your host. Docker allows you to pretty quickly tie together pre-built images/containers like LAMP stacks, Oracle stacks, etc...

It really depends on what your host OS is. If you're running Windows, virtual box is my go to free version. Lots of networking options to help isolate your host machine from your guests. (VM's running on your hypervisor (virtualization software)

There is a good guide here explaining the networking options. https://www.nakivo.com/blog/virtualbox-network-setting-guide/

Are you asking practically or theoretically?

Practically, you will violate your air gap (if it is required for a security plan).

Theoretically, yes. If you want to do some studying on containerization for security purposes, read up on Qubes.

https://www.qubes-os.org/

Well the real question here is why...?

If you're doing this to learn virtualization get esxi, hyper-v or proxmox and set it up - cool youre gonna learn stuff

If it's for security and contain/constraining each activity to it's own security they your best move is Qubes-OS - Read up on it here: https://www.qubes-os.org/

You have the guest additions installed, right? If you choose the Direct3D option during installation of the guest additions, it should enable graphics acceleration for you:

https://www.virtualbox.org/manual/ch04.html#guestadd-video

It sounds like the alternative WDDM driver is worth a try too.

For what you want, the best solution is probalby not virtualization but to add WSL2 to your windows. That way you can run both windows and ubuntu.

When you say it can't be android x86, are you referring to the project or kernel? The android-x86 project offers both32-bit and 64-bit kernels, so I'm a little confused on exactly what you're trying to do.

That's not correct at all. The Phenom II 965 is an old arch and the FX-8320 is a lot more modern. Furthermore the FX-8320 has more cores and the price is right.

Phenom II 965 : http://www.cpubenchmark.net/cpu.php?cpu=amd+phenom+ii+x4+965&id=370

FX-8320 : http://www.cpubenchmark.net/cpu.php?cpu=AMD+FX-8320+Eight-Core

8 GB is on the large side for a minimal Debian install.

> A standard installation for the amd64 architecture, including all standard packages and using the default kernel, takes up 822MB of disk space. A minimal base installation, without the “Standard system” task selected, will take 506MB.

https://www.debian.org/releases/jessie/amd64/apds02.html.en

So a minimal installation will take just over 0.5 GB. Install the things you need for KVM (I don't know, management stuff) and you'll probably stay within 1 GB.

You could look into GNS3 or Eve-NG

Both are tools designed to allow you to simulate/emulate entire network environments and the hosts that run on them.

thanks, I'll look at that, in the meantime I've managed to find a fix:

sudo mv /usr/local/bin/python python-old #example name sudo ln -s /usr/bin/python /usr/local/bin/python

https://stackoverflow.com/questions/29970027/how-do-i-update-pythonpath-from-usr-local-bin-python-to-usr-bin-python/29970431#29970431

On Windows I used a virtual serial port connector https://www.serial-over-ethernet.com/ which did most of the work.

You can set up the virtual serial port in a virtual machine to use a physical serial port on the host computer. This is useful, for example, if you want to use an external modem or a hand-held device in your virtual machine.

However I want to solve this problem on linux machines. Does anyone know a solution?

Ooooh man proxmox is so cool, and I almost chose it for my first real, on-premises (mah house) server (HP Proliant... it's an older model... but it checks out.)

After evaluating the limitations of its orchestration layer for handling containers; and a few other considerations surrounding ease of integration into my larger service environment, I decided to choose libvirt paired with archipel. At least for now.

1. You can install XAPI with modern Xen, but it's not easy (manual install/compilation of XAPI toolstack).
2. XenServer is Open Source, and it has Xen+XAPI toolstack already built inside.

And finally, you can use Xen Orchestra on top, which is also fully Open Source and agent-less.

https://xen-orchestra.com/

Does have a cost associated with it though.

Not that I have anything against proxmox, but I've never heard of it deployed in a business environment, so the experience won't exactly transfer over.

Yes, but it's worth noting that Windows Hyper-V (which is what you're probably using when you run a Linux VM on Windows) is a Type-1 hypervisor. It's just that you're also running other things on the same Windows install as Hyper-V.

And you can get a more lightweight Hyper-V install that doesn't have all of the other Windows components, but then you don't get a nice GUI and all the other Windows services.

have you see this yet? http://www.ovirt.org/Features/ForemanIntegration

also, if you google: foreman ovirt, you'll find some stuff along with some videos that may help.

I have only played with Foreman for a bit. Eventually I felt that SaltStack worked better for my needs.

Cameyo looks to just be using a modified Apache Guacamole. Guacamole is a free and open source HTML5 to remote access web application. My guess is that every time you launch an app on Cameyo it really is a connection into an LXC desktop or something similar that has the flag initial-program set within the Guacamole connection to auto launch an RDP session to a remote app on a Windows server. I'd start here: https://guacamole.apache.org/ and try getting that going, don't skimp on security if you're making it internet facing. It looks like they have custom coded some kind of file upload into though as I don't think that exists in Guac so I'm not sure what you'd do there.

EDIT: Looks like Guacamole actually supports remote apps right out of the box now! I'd just give the documentation a read.

Hyper-V is a good and obvious way to start since you are running Windows 10 and have it already on board, you don't have to install anything.

Since you have mentioned fast switching I would avoid using built-in Hyper-V Console since it's pretty sluggish. Depending on what kind of OS you are running inside your virtual machines I would recommend using some kind of RDP (Windows) or VNC (Linux) manager that allows multiple open sessions. This way you switch just the tabs within the same application and the experience is very similar to what you have with VMware Fusion.

You can start with mRemoteNG which is opensource and supports RDP and VNC along with SSH/Telnet and some others.

https://mremoteng.org/

I don't know what many of those things are you mentioned but :) today I was trying out xen on debian, before I used esxi but I want open source, so they have this flavor of xen that has a gui but I haven't tried it https://xcp-ng.org/

On xen I did make a virtual bridge which gets assigned IP where the nic does layer 2, which was fairly easy, installed a debian virtual machine and logged into it via console, but all of this is in terminal. I couldn't figure out how to install windows yet, had to go to sleep.

Hi /u/uberbewb

Firstly... Don't even think about paying for that licensing at full price for self-education!!! I'm sure there are a few programs out there, the one I would point you towards is the VMUG group, its like $200 USD (Link: https://community.vmug.com/vmug2019/membership/membership-benefits )

If you’re developing a product or capability on top of a hypervisor or that leverages capabilities of the hypervisor layer, I would recommend VMware, this will give you a huge install base that will be familiar how to run your product. Much better than making them add a new hypervisor platform into their environment.

Also, I looked briefly at Xen and XCP, I really liked the look of XCP-NG (https://xcp-ng.org/) it made a platform to build off. I’ll be honest, for me it was a flip of the coin when I made the choice to go down the Proxmox path (more experience with Debian was a key factor).

Also, the RedHat stack is really interesting and has a huge amount of capability, with RHEL, OpenStack, OpenShift, Cockpit, and AnsibleTower you have an entire world of things.

Run Zerotier on the machines you want to be able to communicate will be the quickest setup ever.

Works on windows, linux, macos, freebsd, etc.

If you are choosing between Hyper-V and KVM, let's dig a bit deeper into the comparison:

• Hyper-V requires 24TB of RAM/Host, while KVM needs 12TB.
• As for the CPUs, KVM supports 240 processors, while for Hyper-V, it depends on a generation: 64 for generation 1 and 240 for the second generation.
• Both Hyper-V and KVM offer VM Live Migration, VM Replication supports, Disk I/O Throttling, Hot-plug of virtual resources. However, Hyper-V doesn't allow overcommit resources, while KVM does.
  

And also check some main features of each one. Hyper-V offers:

• Memory support.
• ReFS deduplication.
• Two-node clusters.
• Storage spaces direct improvements.
• Shielded virtual machine updates.
• Encrypted subnets.
  

KVM main features:

• Container support
• Assign any PCI device to virtual machines
• Overcommit resources
• Red Hat Satellite integration
• Low-cost virtualization solution
• Scalability
• Disaster recovery support
  

If you consider other hypervisors as well, check the difference between Hyper-V and VMware and VirtualBox.

In my view, you could check if Veeam Backup and Replication fits your project. Its community edition is free for 10 VMs. https://www.veeam.com/virtual-machine-backup-solution-free.html

Thanks a lot for replying! The online editor is just like a CAT Tool, a translation environment, that is normally used offline as installed software.

Google Docs, unfortunately, is largely incompatible with Microsoft Word files, which is the most frequent format we receive to translate, and causes annoying formatting issues.

Right now after the proofreader is finished working in the editor, where they don't see any formatting of any kind, only the source text, the target field where they translate and tags they need to include in place of formatting such as bolding, etc., we show them a preview of the file using www.box.com, but it is not editable because, so I've been told, box's editing capabilities are limited. Because of this, the proofreader can only make changes to the text and warn us about formatting problems.

I need a solution that would allow them to work on the files online using Microsoft Office as if it were Google Docs. Would O365 be something like this? What would setting it up entail in terms of the technical side? Is there a feasible way of allowing translators in while they are the proofreaders without any need for sharing passwords and the like?

> Creating your own "boxes" requires you to a) push your stuff to the vagrant Cloud (and rely on them) b) tinker around with unmaintained projects BootstrapVz or Veewee

I don't think Vagrant is the right deployment/management solution given your task. However:

Create vagrant boxes

Box Metadata to allow you to host your own boxes

Much more difficult(and costly) for the server to perform these functions than a dedicated Gaming system.

The CPU's(probably Xeon) aren't really built for dedicated gaming. Also remember that you are sharing CPU cycles with other VMs which is going to created minor overhead a la the hypervisor.

You would also, most certainly, need a dedicated GPU card for VMs such as NVIDIA's Grid system.

You could install a standard(that meets hypervisor requirements) GPU to the server chassis and then directly pass through the GPU to the VM, but that would mean you need a GPU per VDI which would require multiple hosts for the GPUs to even fit, but then because they are dedicated you'd lose the ability to load balance across hosts for those VMS because they need to stay on the host that has the dedicated hardware.

You can use Guacamole to access the system via the web browser.

or if you just want document editing.

I've been struggling with the same issue. W7 with W7 guest - when VPN not enabled the guest downloads are fast. (Any speedtest and other downloads) When VPN (NordVPN) is connected 140 would be considered fast usually.

NordVPN on host machine, it's slower than without but still within reasonable for me. Played with a lot of settings with no luck at this point.

Same here....couple of questions though....

1. What brand NIC are you using? I'm wondering if it has something to do with the NIC/software/driver for it.

2. Have you had a chance to use any other virtualization software? I read in one post (another forum) where someone moved to VMWare Workstation and the problem went away.

Edit: I even emailed NordVPN about it and they gave me the impression they were surprised anyone would even try to run their software in a virtualized environment. :)
