Description nigil 2012-10-04 10:59:26 UTC

Description of problem:
Unable to migrate guest from 6.2 to 6.1(backward migration), neither through GUI nor through Command line. Getting an error message "internal error missing hostuuid element in migration data". But migration of VMs from 6.1 to 6.2 was successful and the issue observed when the same VMs are tried to migrate back.

How reproducible:
Install original enterprise edition of RHEL6.2 and RHEL6.2 as Virtualization servers on separate hosts. Configure network. Create VMs on both hosts and migrate VMs from RHEL6.2 to RHEL6.1. 

  
Actual results:
Unable to migrate guest from 6.2 to 6.1. error message "internal error missing hostuuid element in migration data"

Expected results:
Successfully migrate from 6.2 to 6.1 with out any IO failure.

Additional info:
1. Tried the following, but no use.
-Generated uuid : uuidgen
- vi  /etc/libvirt/libvirtd.conf and updated uuid for both the hosts.
- service libvirtd restart
- Migrate VMs, but same error.

2. Support page of RHEL does not include this issue in backward compatibility issue report/section.
https://access.redhat.com/knowledge/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Virtualization_Administration_Guide/Live_migration_and_RHEL_compatibility.html

3. Saw a similar discussion in the below link, but no conclusion.

Comment 4 zhpeng 2012-10-25 06:26:11 UTC

Test with: libvirt-0.10.2-5.el6.x86_64

migrate from RHEL.X to RHEL.Y (X > Y) successful.
migrate from RHEL.Y to RHEL.X (X > Y) successful.

guest xml:
virsh # dumpxml aaa
<domain type='kvm'>
...
  <os>
    <type arch='x86_64' machine='rhel6.1.0'>hvm</type>
    <boot dev='hd'/>
  </os>
...


So it's verified.
