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?
