With that confirmed I checked if I can just point to a bios to break it, and indeed adding -bios /root/seabios_1.12.0-1/usr/share/seabios/bios.bin -bios /root/seabios_1.13.0-1/usr/share/seabios/bios.bin respectively is a make or break change.
As a next step I reproduced the error with seabios rel-1.13.0 from https://review.coreboot.org/seabios.git. It crashes as well. But to make this puzzle even more interesting rel-1.12.0 from the same git crashes as well. I wonder where this trip might end, from qemu to seabios to ... compiler? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1866870 Title: KVM Guest pauses after upgrade to Ubuntu 20.04 To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1866870/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
