I re-opened the discussion that @Christian found on the kvm mailing list and Paolo Bonzini helped identify a fix: enabling the Hyper-V hv_stimer enlightenment. <https://lore.kernel.org/kvm/20200625201046.GA179502@kevinolos/> Although it may not fix the issue for guests which don't support that enlightenment, it works well for my Windows 10 guest, which now has negligible CPU usage when paused.
I've also opened https://bugzilla.redhat.com/1851244 to discuss improving the virt-manager/virt-install defaults for Windows guests. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1851062 Title: Qemu using CPU even when the VM is paused To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1851062/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
