** Description changed: + ======================================== + 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://wiki.ubuntu.com/SergeHallyn_libvirtnest). Check libvirt.log for warning messages. Run /usr/sbin/libvirt-migrate-qemu-machinetype. Check "virsh dumpxml cdboot | grep machine=" for pc-1.0. + 5. Regression potential: The libvirt-mirate-qemu-machinetype script, if it misbehaves, could cause VM definitions to be broken. + ======================================== + 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 # lsb_release -rd Description: Ubuntu 12.04 LTS Release: 12.04 # apt-cache policy qemu-kvm qemu-kvm: - Installed: 1.0+noroms-0ubuntu13 - Candidate: 1.0+noroms-0ubuntu13 - Version table: - *** 1.0+noroms-0ubuntu13 0 - 500 http://de.archive.ubuntu.com/ubuntu/ precise/main amd64 Packages - 100 /var/lib/dpkg/status + Installed: 1.0+noroms-0ubuntu13 + Candidate: 1.0+noroms-0ubuntu13 + Version table: + *** 1.0+noroms-0ubuntu13 0 + 500 http://de.archive.ubuntu.com/ubuntu/ precise/main amd64 Packages + 100 /var/lib/dpkg/status
