Bug Description
=======
Note - when SRU'd, we should add a note to the 12.04.1 release notes
SRU Justification:
1. Impact: pc-0.12 machine type fails to migrate in precise, fails
to work with wmvga, as well as probably several other bugs
2. Development fix:
3. Stable fix: same as development fix
4. Test case: define and start a pc-0.12 VM (as per https:/
5. Regression potential: The libvirt-
=======
Just upgraded my virtualization hosts from Ubuntu 11.10 to 12.04. However, I noticed that the clock in the guests completely stops after live migration from one host to another. In addition, migrated guests hang on shutdown or reboot - only 'virsh destroy' helps.
Live migration always worked great for me on Ubuntu 10.04 to 11.10, I never had any problems. What has changed in 12.04???
Guest are Ubuntu 11.04, 11.10 and 12.04.
Hosts are Ubuntu 12.04 LTS x86_64 running kernel 3.2.0-24-generic

Thanks for reporting this bug. I'll try to reproduce.
Could you post the xml file for one of the domains that fails to migrate?
Could you edit /etc/libvirt/ libvirtd. conf on both hosts to set log_level = 1, then restart libvirtd (sudo stop libvirt-bin; sudo start libvirt-bin), re-try the migration, and post the /var/log/ libvirt/ libvirtd. log and /var/log/ libvirt/ qemu/VMNAME. log files?
