We have four identical Ubuntu servers running libvirt/kvm/qemu, with access to CEPH rbd filesystems. Guests can be live migrated between them. However, live migration leads in ~30% of the cases to guests being stuck at 100%. Only a few times we had the patience to wait, and upon logging in our passwords were said to be expired; thus we couldn't log in.
This happened mostly to long running VM's, but not all of them; this makes debugging hard. These servers run ubuntu 14.04 (trusty): ceph: 0.94.7-1trusty qemu: 2.0.0+dfsg-2ubuntu1.22 linux: 3.13.0.88.94 libvirt: 1.2.2-0ubuntu13.1.16 Is this what you request? -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
