BTW 2.11 -> 3.1 without the cloud archive in mind matches a migration from Bionic to Disco. I have checked my test logs (a bit ago since Disco itself is EOL). But at least this January 13 and 16th the migrations 2.11 -> 3.1 still were ok.
In my log that was between B: qemu: 1:2.11+dfsg-1ubuntu7.21 libvirt: 4.0.0-1ubuntu8.14 D: qemu: 1:3.1+dfsg-2ubuntu3.7 libvirt: 5.0.0-1ubuntu2.6 7.2.0 (11:51:19): Test live migration (extra option '') of a bionic guest testkvm-bionic-from/testkvm-disco-from 7.2.1 (11:51:19): live migration (extra option '') testkvm-bionic-from -> testkvm-disco-from => Pass 7.2.2 (11:51:26): Check if guest kvmguest-bionic-normal on testkvm-disco-from is alive => Pass @Sam - please feel free to copy&paste that info into the new bug you are gonna be creating. /me is now stopping to bump this resolved case here -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1848497 Title: virtio-balloon change breaks migration from qemu prior to 4.0 To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-archive/+bug/1848497/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
