** 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
