I only have 64 bits servers, all with Intel VT-x CPUs and known to work with
(other) 64 bits guests.

I believe the CentOS and Ubuntu systems are 32 bits,
The Red Hat is 64 bits.
All these VM work on all our FreeBSD hosts.

There was a typo there. I wanted to say "on a Windows XP host".

Hum. It may be dependent on the systems settings i use. Come to think about
it the GENERIC 8.0p3 kernel i tested upon was compiled with some
optimizations (CFLAGS+= -mtune=k8 -mmmx -msse -msse2 -msse3 -mfpmath=sse). I
will run a test with default compilation options.

However, i don't plan to use FreeBSD i386 hosts because most of our servers
have more than 4 GB RAM.

Best regards, 

Hubert
