A screenshot with the most relevant virt-manager settings is added. I tried again all my nested virtual machines settings. An overview of my configurations: NOK: Ubuntu 21.10+Virtualbox 6.1.30 -> Ubuntu 22.04 Mate with Virt-Manager+KVM -> Ubuntu 14.04 OK : Ubuntu 21.10+Virtualbox 6.1.30 -> Ubuntu 22.04 Budgie with Gnome Boxes -> Ubuntu 14.04 OK : Ubuntu 21.10+Virtualbox 6.1.30 -> Ubuntu 21.10 with Virt-Manager+KVM -> Ubuntu 14.04
All Ubuntu 14.04 are the same VM qcow2 image. Both settings of the virt- manager are exactly the same with respect to the displays. Note that the differences in response times between OK and NOK are higher than a factor 10. ** Attachment added: "Screenshot from 2021-12-08 11-43-43.png" https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1953628/+attachment/5546319/+files/Screenshot%20from%202021-12-08%2011-43-43.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1953628 Title: Too high CPU load in qemu-system-x86 compared to Ubuntu 21.04/21.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1953628/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
