do this, mainly because the 64bit version can handle the large
amounts of memory typically found in dedicated servers.

"With Red Hat Virtualization, 32-bit hosts runs only 32-bit
paravirtual guests. 64-bit hosts runs only 64-bit paravirtual guests.
And a 64-bit full virtualization host runs 32-bit, 32-bit PAE, or
64-bit guests. A 32-bit full virtualization host runs both PAE and
non-PAE full virtualization guests."

Yes, so I can run 32bit guests on 64bit host,but with full
virtualization. How do I know if a) my system supports it, and b) my
kernel / OS has full virtualization enabled?
I have an intel Core 2 Duo 6750 CPU, which has Intel VT, and it's
enabled in the BIOS, as can be seen here:
