[libvirt-users] Odd Virsh Capabilities response

[W Kern]

Tried to migrate a few VMs from existing system to an older host that we 
threw in the rack to facilitate some server reshuffling.

Migration complained about lack of capabilities (which I expected its an 
older server) but when I looked at what I should throw into the xml file 
I got a core2duo when it should have been at least Penryn or something 
(Xeon E5345)

Of course the VMs work fine with that cpu def so its not a bit deal at 
the moment, but I am still curious

Is it some sort of lookup table bug or is the server BIOS wonky?
