Hello! Unfortunately the bug has apparently reappeared. I have a Windows 10 running in a VM, which after my today's "apt upgrade" goes into pause mode after a few seconds of running time.
Tail output of my /var/log/libvirt/qemu/win10.log char device redirected to /dev/pts/1 (label charserial0) 2020-05-05T08:53:23.733051Z qemu-system-x86_64: warning: host doesn't support requested feature: MSR(48FH).vmx-exit-load-perf-global-ctrl [bit 12] 2020-05-05T08:53:23.733122Z qemu-system-x86_64: warning: host doesn't support requested feature: MSR(490H).vmx-entry-load-perf-global-ctrl [bit 13] 2020-05-05T08:53:23.736093Z qemu-system-x86_64: warning: host doesn't support requested feature: MSR(48FH).vmx-exit-load-perf-global-ctrl [bit 12] 2020-05-05T08:53:23.736110Z qemu-system-x86_64: warning: host doesn't support requested feature: MSR(490H).vmx-entry-load-perf-global-ctrl [bit 13] 2020-05-05T08:54:04.912098Z qemu-system-x86_64: terminating on signal 15 from pid 1593 (/usr/sbin/libvirtd) 2020-05-05 08:54:05.112+0000: shutting down, reason=destroyed Apt upgraded packages (from /var/log/apt/history.log): Start-Date: 2020-05-05 09:32:02 Commandline: apt upgrade Requested-By: andreas (1000) Install: linux-image-5.4.0-29-generic:amd64 (5.4.0-29.33, automatic), linux-modules-extra-5.4.0-29-generic:amd64 (5.4.0-29.33, automatic), linux-headers-5.4.0-29-generic:amd64 (5.4.0-29.33, automatic), linux-modules-5.4.0-29-generic:amd64 (5.4.0-29.33, automatic), linux-headers-5.4.0-29:amd64 (5.4.0-29.33, automatic) Upgrade: linux-headers-generic:amd64 (5.4.0.28.33, 5.4.0.29.34), linux-libc-dev:amd64 (5.4.0-28.32, 5.4.0-29.33), linux-image-generic:amd64 (5.4.0.28.33, 5.4.0.29.34), linux-generic:amd64 (5.4.0.28.33, 5.4.0.29.34) End-Date: 2020-05-05 09:33:11 Kind regards, Andreas -- 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
