As a fun experiment, I do my day-to-day computing entirely in a Virtualbox Windows VM guest that I've given 2 cores, 150GB of storage and 4GB of RAM. I'm about a year and a half into the experiment and still chugging along. It's a surprisingly performant day-to-day system, which I can snapshot to try out things, move to other machines if I need to, make backups etc. About the only thing it doesn't do well is really CPU intensive or GPU intensive operations. But it works fine for 2 monitors, web browsing, watching videos, etc. It's kind of surprising actually. From time to time I'll also spin up some Linux VMs and do various dev activities in a real Linux, which I usually just background and ssh into from my Windows VM. It's kind of nice having a virtual rack of machines to monkey around on. Less impressive has been trying to get Ubuntu to not feel terrible, but Centos works fine. If I need better performance, I'll dive back to the host OS and do those things, but it's mostly just for gaming or music production. Bonus, my host OS has stayed relatively free of junk and stays really snappy, even all this time later. My only recent problem is that the Windows 10 updater won't qualify the VM guest for the upgrade. So I'll probably have to grab the ISO and try it that way.

I do this because my employer has some silly policies and it was the only way they would let my run Linux on my localhost. Really I forget that I'm in the VM.. RAM is a little scarce, but all in all it works surprisingly well.

  Same reason here, our IT department only supports windows and I've been mostly using VBox to work in linux at work for the past 3 years without any incident whatsoever. The clipboard, mouse and keyboard sharing are really fantastic. It really makes you forget this is a guest OS.

  i've tried doing the same but the performance hit is unfortunately too big for me to find it acceptable. silly policies.
  - ewzimm 11y ago
    You should try it in Hyper-V. GPU-accelerated desktops are still no good, but everything else performs really well.
    - ake1 11y ago
      from what i understand it, hyper-v is only supported by a couple of distros and even then, the performance gains are not that noticable. definitely worth looking into none the less, thanks.

I need 32GB RAM, so no chance for virtualization. But Kubuntu handles snapshots (BTRFS) and moving between computers (move SSD) without a glitch.
- paramsingh 11y ago
  How has your experience with BTRFS been? I'm intrigued and want to try it out.
  - cmurf 11y ago
    I have mostly good experiences with it. I have more examples of surprising good things it does and scenarios it will survive OK. But then the edge cases, if you hit them, can be brutal. So you have to amp up the backup strategy for important data, just because of the unknown factor. Development is really incredible the 4.2 merge window included almost 2000 additions for Btrfs, and almost as many subtractions. It's really hard for a mortal person to keep track of the bugs, bug fixes, optimizations and regressions. For example right now, a rather major regression in ext4 conversions: The convert goes find, mount is fine, rollback is fine. But if you scrub it, hard panic; even console is lost, let alone all services. But the fs survives. If you balance it, corruption of the fs (and so far not repairable). So right now, which could change at any moment, I'd say avoid ext4 to btrfs conversions. Create a new fs, and keep backups. Usually it's pretty good about at least mounting read only so you can update a backup, even if the fs is beyond repair. Despite piles of kernel features, it still lacks much needed notification to user space of device failures. For multiple device volumes, you probably want to be informed of either flakey or failed devices and right now you have to be watching for it. Some edge cases in degraded operation exists when replacing devices that you have to be careful of, etc. So this whole area needs work, which means more developers interested in such things are needed. But anyway, it's going pretty good.

move to other machines if I need to Last time I tried that meant having to do a rather slow and disk hungry export followed by an import. Was I doing it wrong and is there no way to just copy the disk and machine definition, or are there other ways already?
- greyboy 11y ago
  I never do the export/import process for that exact reason. If I need to move a VM for some reason, I copy the entire VM directory to the new location then open VirtualBox and use "Machine" -> "Add ..." and select the directory with the VM config and files. I hope that helps, unless I missed something.

    It would be nice to have the whole thing on an external SSD, which I could switch between my desktop and laptop. Does this work or could the VMs get corrupted?

      I have had no issues running a VM on an external drive.
      - k__ 11y ago
        Even if you ran it on one machine with a Linux host and on another with a Windows host?
        bradleyland 11y ago
        I've not moved VM's between Windows and Linux, but it works fine going back and forth between OS X and Windows. The only caveat being that you have to re-visit the VM's settings for things like host volume mapping and especially networking config.

Same thing here. At work my host OS has nearly nothing installed on it, with an unusual toolbar and background color to remind me I'm not on the "right" machine. I do all of my work in a VM, and as my org gets new machines, I xcopy the VHD over with minimal downtime. Full screen remote desktop is fine. My work is generous with hardware dollars, so I'm not really in any need of more memory or disk space. That said, my work doesn't really involve anything involving lots of screen drawing. Video sucks through remote desktop (audio/video de-sync or rdp connection drops), so if I need to watch a video (presentation or youtube), I either suffer through it or do that on the host machine.

> the Windows 10 updater won't qualify the VM guest for the upgrade I was able to get my VM to qualify. Make sure you have the required hotfixes, otherwise you will not qualify -- KB3035583 and KB2976978 for Win8.1, KB3035583 and KB2952664 for Win7 SP1. Then reboot and run the batch file given here: http://superuser.com/a/922442 http://superuser.com/a/922442

I may have to try this again later this year when I buy new desktop parts in anticipation of Fallout 4. In the present time though, I tried this once on my work laptop, running a Core i7(2011), with 8GB RAM and Windows 7 as the Host OS and VM OS. With the usual platter HDD, Visual Studio got bogged down so much during compilation times(we had a really big project), that it became too unfeasible to continue using.
