Ok, in your log we see error: kvm run failed Invalid argument EAX=b0008004 EBX=7ffaa3b0 ECX=00000004 EDX=b0000004 ESI=7ffa9c70 EDI=000f246a EBP=000f244b ESP=00006cec EIP=000eb4ae EFL=00010082 [--S----] CPL=0 II=0 A20=1 SMM=0 HLT=0 ...
That is why your guests fail. I was preparing a UEFI and a Bios guest on hirsute. Working fine so far, then I upgraded all packages. Working fine still FYI - kernel was on 5.8.0-29-generic Then I upgraded to 5.10.6-051006 from the mainline ppa. (https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.10.6/) Guests still working fine :-/ @Kernel Team do you know about any changes coming? ** Changed in: libvirt (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1909495 Title: Unable to start BIOS VMs since Linux 5.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1909495/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
