Hi Bert, thanks for the extra info. I'm still confused by "Ubuntu 21.10+Virtualbox 6.1.30 run on the bare metal a Ryzen 3 2200G" vs "highest level is always Ubuntu 14.04". Probably a terminology thing what in virtualization is up and down :-) Let me try to make sense of it :-)
So are we talking about: a) PC -> Ubuntu 21.10 -> Virtualbox 6.1.30 -> Ubuntu 21.10 -> virt-manger/qemu -> Ubuntu14.04 b) PC -> Ubuntu 21.10 -> Virtualbox 6.1.30 -> Ubuntu 22.04 Mate -> virt-manger/qemu -> Ubuntu14.04 c) PC -> Ubuntu 21.10 -> Virtualbox 6.1.30 -> Ubuntu 22.04 Budgie -> virt-manger/qemu -> Ubuntu14.04 d) PC -> Ubuntu 21.10 -> Virtualbox 6.1.30 -> Ubuntu 22.04 -> virtualbox -> Ubuntu14.04 And of these a+d are "fast" and b+c are "slow" - is that correct? And the comparison a->b/c is what makes you assume it is a regression? As of today the virtualization components of 21.10 and 22.04 (qmeu/virt-manager/libvirt) are still mostly the same as I only planned to upgrade them in ~Jan/Feb which makes this extra interesting. So maybe some other component in 22.04 changed already that makes this happen. If my above summary is wrong, could you please provide the real setup in the same less-misleading form I tried to write it up? -- 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
