Recommendations For Home Virtualization? 384

An anonymous reader writes "I'll have to upgrade my home computers sometime in the next few months and I'm thinking it's time to swallow the virtualization pill. Besides the ease of switching between Windows and Ubuntu, I'm looking mainly for the ability to save machine state in order to be able to revert to a known working state. Googling turns up mostly guides from 2009 and earlier. Is VMWare ESX pretty much the way to go? Performance does matter — not for gaming but I am heavily into photography, so apps like Lightroom and Photoshop need to run well. Thanks for any insight."

        I agree, VirtualBox is a lot easier to set up and run, is easy to maintain, and easy to move images between machines. It's what I've been recommending to everyone for a while now.

            He wants to run Photoshop and Lightroom in it though. I don't know how well that does with the virtualized video cards on any platform though. I know there are a lot of games I can't play in a virtualized environment, only for that reason. If I could, I wouldn't have a real Windows bootable partition at all.

          IMO if he wants to do that sort of thing, he should run Linux in VirtualBox on a Windows 7 host, and run Photoshop and friends on the host. Best of both worlds, right? That's what I do, except I use the Windows host mostly for gaming...

        If your'e looking to have a specialized server that ONLY hosts VM's, then there is some merit to running ESXi. It's free too, and the resource footprint is pretty small. Personally, I would only use VirtualBox or VMWare Server in cases where I still wanted to use the machine running the VM's as a desktop in it's own right. Otherwise, ESXi is the way to go. That said, I DO use my home desktop to serve VM's in addition to regular desktop usage, so it runs Virtualbox :). I use ESXi for virtualizing servers at work though.

    For stable server virtualization vmWare ESXi is pretty much the king at the moment, unless you want to pay an insane amount. It's free (as in beer) stable, easy to manage, fast and scalable. Sadly the management tools are windows only, I highly recommend it, if you have suitable hardware.

    For workstations it's a bit less clearcut. Generally you want a primary OS in your workstation where you do most of your work, and secondary OS that you boot up in a virtualized environment. The three primary choises are KVM, XEN and OpenVS. They all have performance penalties, and I am not aware of any clear cut advantage for any of the three.

    You mean desktop virtualization? Do you need to run 2+ OSes at the same time? That's what virtualization is for. Or do you need to just suspend and restore states? You can get away with hibernation for that. Or do you mean go back in time to a known working configuration? Windows can do that (System Restore), but I don't really see why you would need that on your main machine. If you're trying stuff out, you should try it inside the VM anyway (you use Workstation or VirtualBox for that).

    ESX is nice, but it's not what you think. You don't get a local console (last time I checked, anyway), you're supposed to access it from SSH or VNC. It also designed for datacenter stuff (like SAS disks and controllers. It doesn't support IDE for example). You're looking for VMWare Workstation (Paid) or VirtualBox (free for non-commercial use), which are pretty fast. Paravirtualization (ESX or XEN) will give ~98% speed on Linux (on a PV kernel) and Windows only works well if you use GPLPV drivers, otherwise is slow as hell.

    I'd just recommemd you stay away from virtualization if you're just a desktop user. Unless you're trying out shareware/malware/stuff that can break your install. If you're upgrading, why not use the old machine to try ESX, XEN and other stuff and figure out yourself how you want to use it? Stick to dual-boot for now.

      I'd just recommemd you stay away from virtualization if you're just a desktop user.

      I'd recommend the exact opposite.

      Virtualization rocks for keeping things separate. My personal machine has a quad core CPU with 8GB of RAM. I've got 2-3 VMs running most of the time so I can keep things separated and do different things. It also lets me have Linux, FreeBSD and Windows guests without the power/space requirements of multiple machines.

      VMWare workstation is only about $200 or so (maybe even $150), and I gather Server is free (but at the time running it on Vista 64 wasn't very easy). The ability to snapshot machines or sandbox things is really awesome. It also allows me to have multiple dev environments set up which don't interfere with each other, and a quick linked clone of a machine gives me a disposable test-bed in about 3 minutes if I think I need something new and isolated.

      The only thing I regret is that my CPU is one notch down from being able to do 64-bit guests because I wasn't aware of that at the time.

      For me, a big machine with loads of RAM and disk and VMWare makes for a really sweet setup. If you've got the resources on the box, it really does make some things easy. Soon I'll migrate my second physical box (an old XP machine) into a VM so I can keep some legacy software installs going without worrying about an aging machine.

    I'm running multiple VM systems including VMWare Server, VMWare ESX, VMWare Workstation, xen, KVM and VirtualBox.

    VMWare Server is going away and sort of a pain to manage. However, it was free and worked decently. I have since replaced it with VMWare Workstation on my desktop and laptop systems. I use VirtualBox on my Mac laptop because it's free and was the easiest/cheapest to get going.

    On my servers I am running VMWare ESX, xen and KVM on AMD systems (mostly dual core, but a couple quad core systems in the mix).

    VMWare ESX was the most finicky as to installation but has been pretty simple to manage. The remote console options are simple. The VSphere management client is Windows only though. There is support for command line administration, but it's somewhat of a bear. You can script around it though and many people have done so and provide scripts online. Check out the VMWare community pages. Support is so so..

    Xen was my workhorse for the longest time, but since my primary OS is RedHat/CentOS and RH is moving towards KVM, I've also been moving to KVM. The GUI management tools work fine, but are not as polished as VMWare ESX. However, it very much makes up for it in being able to do just about everything from the command line. I can deploy an image with a single command and this works wonderfully for testing. Performance is awesome with both xen and KVM. Well, the caveat is that some network intensive stuff seems to be bottlenecking somewhere, but it only has a single gigabit NIC across 8 VMs. I'll be adding another NIC in the next couple weeks and either bonding the adapter or just splitting them up.

    Be aware that client/guest images generally do not have video acceleration so many games will fail to load. If you're running VMWare Workstation on a laptop, or the more recent KVMs then there is some measure of acceleration, but not 100%. Also, sound can be finicky especially across the network.

  • I have done something similar. Some points. 1. First pay attention to what CPU you get. Some Intel CPU's do not support VT extensions. Most AMD CPU's do. 2. I have always found better performance if the VM virtual disks were on their own disks vs. the OS, and then vs. each other, if possible. 3. I have used Photoshop on a Windows VM with VMware Workstation, and did not see graphics performance issues as described. VMware workstation is not free, but is not too $$$, and has some nice features vs. the fr
  • I have been using KVM [] on my home workstation for a few months now and I can highly recommend it. I typically use it for testing different linux distros, files systems, server configurations, etc.

    If your system supports VT-x or the AMD equivalent the performance is very impressive, almost no noticeable difference. The virt-manager [] produced by Red Hat makes creating and configuring virtual machines a snap with its friendly user interface.

    It supports many useful things like, headless VNC mode (defaut), s
  • ...Acronis. You can use it to image a machine, so that you can easily restore it to a known working state again later, even on different hardware. I'm a big fan of trayless disk caddies too, so you could have something like this: [] that would let you swap disks in and out easily. I like it because not only can I upgrade my machine on a new disk with no chance of thrashing my currently working machine, but I can also use the additional tray slots

  • If you are doing it just for OS state reasons, and you're using Windows, is to just run Windows 7 and boot from a differencing VHD, keeping your data files outside of it.

    Its no more complex than safely using virtualization to do what you want (and ensuring you don't lose data on a revert) but you're running bare-metal. Virtualization doesn't buy you much if you're just doing a single OS.

      For anyone considering Microsoft Virtual PC, please keep in mind that it cannot run 64-bit guests. For me this was a non-starter.

  • It's not really for you. While it does squeeze significantly more performance, especially with I/Os, out of a system. It is really too much enterprise and not enough desktop to make for a happy GUI experience. Virtualbox and VMware Workstation are excellent products, I would recommend running Linux VMs on a Windows host to maximize your Photoshop performance. I run the other way around, with Linux host and Windows guest because my important apps are Linux apps. For laptops I would also recommend the Linux-o

  • As others have posted and others sill undoubtedly post, we need more information to give you the recommendation you want. Making some assumptions from your question, it sounds like you want to virtualize your workstation. For full baremetal performance, don't virtualize your primary OS. The technology isn't there yet, but VMWare is making huge strides with their VMView [] product. Set up properly, you can have CAD running in a virtual machine on a server with a thin client displaying the output with very r

  • Okay here's my experience of using virtualization at home and with a bit of office work:

    Xen - for the time I started using it in 2008, a really big advantage was paravitualization mode which allows to run virtualized linux instances really fast -- in that respect Xen is awesome, however there are several disadvantages: in theory you could run anything that supports paravirtualization mode, so that means you could run All the BSDs, but I never succeeded of installing any of them when I tried, windows of cour

  • VMWare Workstation is king for desktop virtualization. People will recommend all sorts of free/opensource tools, but the features simply wont compare to VMWare. DirectX support, snapshots, seemly windows etc etc etc. It does cost about $150, but well worth it if you have serious needs.
  • I initially read this comment as "I am heavily into pornography."
  • I am very happy with my setup. And I arrived at this after much trial and error. I am mostly a Linux person but I reached a point in my life where I could not deny that I need both Windows and Linux to get stuff done. So I setup a quite beefy 6 core CPU machine to handle all my home computing needs and then some. You don't have to go all out like I did, if your needs are simpler. Here is the setup details:
