Today I created a new guest machine, and migration works for it! So I compared xml files from old and new guests and noticed the difference
<type arch='x86_64' machine='pc-0.12'>hvm</type> (old guests) vs. <type arch='x86_64' machine='pc-1.0'>hvm</type> (new guest) I changed all guest configs to pc-1.0 and now migration is working again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1001625 Title: Guest clock stops after live migration on Ubuntu 12.04 hosts To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/1001625/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
