[Users] Live migration not working for one guest in two node cluster

[David Wilson]

Hi guys,

I am running an oVirt system which comprises of two CentOS-6.2 nodes.
I currently have two guests provisioned - one of which migrates 
perfectly between my nodes. The other guest fails to migrate with the 
following error in my oVirt web GUI:
/Migration failed due to Error: Fatal error during migration (VM: tux, 
Source Host: node01...../

Looking at my /var/log/libvirtd.log on the source node I see the 
following error just as the migration tasks starts - I am not sure if 
it's related?
/2012-07-10 20:25:16.834+0000: 4533: debug : qemuDomainDefFormatBuf:1201 
: Removing default USB controller from domain 'tux' for migration 
compatibility
2012-07-10 20:25:16.834+0000: 4533: debug : doPeer2PeerMigrate3:2348 : 
Prepare3 0x7fe0800c10d0
2012-07-10 20:25:16.837+0000: 4533: error : 
virNetClientProgramDispatchError:174 : XML error: invalid security type

/Please may I ask for some guidance on what this means and how I can 
resolve the problem that I am experiencing?
