Performing verification for Focal. I installed 5.4.0-65-generic to a c5.metal AWS machine, and installed ubuntu-desktop and a KVM stack. I install xrdp and verified I could reach the VMs desktop.
I installed virt-manager, and configured the Windows 2k19 VM in accordance with the testcase section, carefully making sure the Cascadelake-Server-noTSX processor is selected and the features in place. I installed Windows, and installed the virtio drivers. From there I enabled Hyper-V and restarted. The machine got stuck during reboot, after the hyper-v feature had installed and configured. Looking at the performance tab, the machine is stuck at 100% CPU, see 5.4.0-65-generic.png attached. I then enabled -proposed and installed 5.4.0-66-generic, and kexec rebooted. From there I started the windows VM, which came up properly to the desktop. Looking at the performance tab, CPU usage is low, and is what is expected. See 5.4.0-66-generic.png attached. The 5.4.0-66-generic kernel fixes the issue, happy to mark as verified. ** Tags removed: verification-needed-focal ** Tags added: verification-done-focal -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1911848 Title: kvm: Windows 2k19 with Hyper-v role gets stuck on pending hypervisor requests on cascadelake based kvm hosts To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1911848/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
