I have tried some other configuration and added those to the overviews: DT = DeskTop and LT = LapTop.
a) DT -> Ubuntu 21.10 -> Virtualbox 6.1.30 -> Ubuntu 21.10 -> virt- manger/qemu -> Ubuntu14.04 b0) LT -> Ubuntu 21.10 -> Virtualbox 6.1.30 -> Ubuntu 22.04 Mate -> virt-manger/qemu -> Ubuntu14.04 b1) DT -> Ubuntu 21.10 -> Virtualbox 6.1.30 -> Ubuntu 22.04 Mate -> virt-manger/qemu -> Ubuntu14.04 b2) DT -> Ubuntu 21.10 -> Virtualbox 6.1.30 -> Ubuntu 22.04 Mate -> GNOME-BOXES -> Ubuntu14.04 b3) DT -> Ubuntu 21.10 -> Virtualbox 6.1.30 -> Ubuntu 22.04 Mate -> virt-manger/qemu -> Peppermint 10 c1) DT -> Ubuntu 21.10 -> Virtualbox 6.1.30 -> Ubuntu 22.04 Budgie -> GNOME-BOXES -> Ubuntu14.04 c2) DT -> Ubuntu 21.10 -> Virtualbox 6.1.30 -> Ubuntu 22.04 Budgie -> virt-manger/qemu -> Ubuntu14.04 d1) DT -> Ubuntu 21.10 -> Virtualbox 6.1.30 -> Ubuntu 22.04 -> virtualbox -> Ubuntu14.04 d2) DT -> Ubuntu 21.10 -> Virtualbox 6.1.30 -> Ubuntu 22.04 -> virt-manger/qemu -> Ubuntu14.04 Only b0 and b1 are very slow, all other configurations work fine. The newest configurations are b0; b2; b3; c2 and d2. b0) I backup my VMs weekly to my laptop and despite the only 8GB of memory, I tried the b1 configuration on my Sandy-Bridge laptop. The result was worse than on the Ryzen, because my laptop CPU (i5-2520M) is 2 to 3 times slower. Without any inputs to the DT the CPU load in idle is 80% caused mainly by compiz and it takes 1 minute to start the terminal. I have addedd that as b0. b3) I also have Peppermint 10 as qcow2 file,so I tried Peppermint. I have added that configuration as b3 and that configuration b3 was fine, I would even call it responsive :) Summary: I only have a problem with the combination Ubuntu Mate 22.04 and Ubuntu 14.04, all other combinations are fine. Maybe the animations in Ubuntu Mate 22.04 and Ubuntu 14.04 do bite each other. I'm downloading the latest Ubuntu Mate 22.04 ISO and I will reinstall configuration b1 from scratch tomorrow, to eliminate any installation problems. -- 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
