I can reasonably assume that this solved my problem. I've live migrated 41 VM's 5 times between 2 hypervisors without the 100% cpu problem appearing.
My production servers run 2.0.0+dfsg-2ubuntu1.22, and still observe the same problem. Attached is the patch that I created with quilt in debian/patches; This one mirrors the 4 patches that are listed in the debian bugreport[1]. The patch should apply cleanly with qemu 2.0.0+dfsg-2ubuntu1.24 (from trusty-security). Let's hope others can benefit from an ubuntu update :) [1] https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=786789 ** Patch added: "backport-fixtime.patch" https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1297218/+attachment/4693333/+files/backport-fixtime.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1297218 Title: guest hangs after live migration due to tsc jump To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1297218/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
