[one-users] error : virDomainDefParseXML:8303 : unknown OS type hvm

[Gerry O'Brien]

Hello Jaime,

     Below is the domain information for a VM that runs on all my hosts 
except two specific one. All hosts are identical PXE boot images except 
for some /var directories & files (which I have double checked to make 
sure the permissions are identical). I can live migrate the VM around 
all my hosts except the two where is fails with the above error message. 
It to me looks like there is some additional information that is stored 
in OpenNebula outside the two failing hosts, possible where '<type 
arch='x86_64'>hvm</type>' is defined? Any ideas?

         Regards,
             Gerry
