Another test with NTP disabled on the servers (but enabled on the guest): Still running qemu-git-2.1.0-rc2-git-20140721
server-a:~$ ntpdate -q cl0 stratum 3, offset -29.405612, delay 0.02597 server-b$ ntpdate -q cl0 stratum 3, offset -32.990292, delay 0.02597 The guest is running NTP, hosted on server-b for more than 10 days. Its NTP reports:. ntp.drift=-35.387 ppm. This matches the offset of server-b (32.99 seconds in 10 days, 19h21) very well: -35.33 ppm. Doing a live migration of the guest from server-b to server-a: Guest does not hang at all (NTP offset after migration: 0.38s). So if NTP is not running on the hosts, then there are no issues with the guest, it seems. -- 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
