Hi Andreas, so the only upgrade you did to trigger this for you was to bump the kernel from 5.4.0-28.33 to 5.4.0-29.34 - nothing else? I have not (yet?) heard other similar reports, but it might be just too early? At least on my system for now things still work with the new kernel like before.
I'd recommend filing a new bug, refer to this one as maybe being related and adding the following right away: - kernel version (you have this here I know) - qemu/libvirt/seabios/ovmf version (if you don't mind just attach `dpkg -l`) - guest XML (if using libvirt) otherwise the qemu command-line - add a cross check and report what happens with other guests configs (e.g. non windows, using another bios as the former issue was tied to seabios, use different guest CPU types) - the full /var/log/apt/history.log - a date when you last started the VM successfully (not just still-had-it-running, but started it) and the date when it started to fail (probably yesterday then I guess) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1866870 Title: KVM Guest pauses after upgrade to Ubuntu 20.04 To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1866870/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
