Re: [Xen-users] Pacifica/VT again
Are you meaning a x86 XenU on a x86_64 host system?
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

This already works with the Xen's VT support I believe.
