Re: [Xen-users] Pacifica/VT again

An _unmodified_ x86 domU on an x86_64 host.

64 bit Xen doesn't support the 32-bit Xen interface, so explicitly 
Xen-native 32-bit guests can't run on it even though fully-virtualised 
unmodified guests can. i.e.:
32-bit host: 32-bit Xen-native guests 32-bit host w/VT or w/Pacifica: 
32-bit Xen-native guests, 32-bit unmodified guests 64-bit host: 64-bit 
Xen-native guests 64-bit host w/VT or w/Pacifica: 64-bit Xen-native guests, 
64 or 32 bit unmodified guests
Cheers,
Mark
