January 11, 20206 yr I'm trying to setup a ubuntu desktop VM but I'm getting an issue where it freezes after a couple minutes. I haven't even been able to finish installation because it freezes before I can install. I'm running Bionic Beaver. I looked at other solutions and nothing I've found has solved my issue so far. I've changed cpu pinning, made sure I have bios setting correct. I attached my diagnostics and XML file for my VM. Any ideas on what might be the issue? bernard-diagnostics-20200111-1443.zip ubuntudesktop.txt
January 17, 20206 yr A few things to try: 1) UEFI boot mode. Use OVMF instead of SeaBIOS. See if that makes a difference. 2) Try i440fx (instead of q35). 3) Try setting the CPU to emulated instead of host-passthrough. If none of those work, let us know and I can try to recreate the issue on our end.

If none of those work, let us know and I can try to recreate the issue on our end. I just tried them all but no luck: I have it setup with SeaBIOS, it wouldn't even launch if I had it set to OVMF. No iteration of i440fx would work, all of them gave me this error. I updated it with emulation but it still didn't work. Froze after a couple minutes after launch.
January 23, 20206 yr I find switching to i440fx from q35 the pci structure doesn't automatically fix itself up. In practice its easier for me to create a whole new VM than try to fix the xml.

When changing BIOS and machine type, ALWAYS start a new template.

Thanks for the tip I didn't know I had to do that with the machine type as well. I started a new template, changed machine type to i440fx v4.2 and I'm still getting the same issue. Still getting random freezing. Edited January 26, 20206 yr by Blairwin
April 12, 20206 yr Author Still having this issue and having no luck trying to fix it. There's a ton of cpu activity, but still nothing happens. I was able to get past the installer but it still came up with an error. Ubuntu desktop giving me a ton of headaches.
November 30, 20205 yr I was having this problem, but it's fixed now. trying to install Ubuntu with Q35, OVMF.. All I did was recreated a new VM but with i440fx-4.2 instead of Q35 and it no longer freezes during the setup. I wish Unraid was a little more descriptive on what all those machine type are..
December 25, 20205 yr Author I started up a Ubuntu VM today and it's working now. Using 18.04.03 Desktop. The only setting I changed was switching Machine to i440fx-4.2. I thought I did this before and it didn't work so I'm not sure why it's working now but it is.
