I presume they ripped you off at the hardware store by
keeping one bit for themselves while charging the full
price for a 64bit system :)

just set the personality for the guest (in the guest
config) and everything should be fine, as long as the
host kernel supports the 32bit API.

yes, rsync just copies the files, which is fine and
doesn't care about 64bit vs 32bit, nevertheless, you
should set the personality correctly.

as I said, kernel config should include the 32bit API
CONFIG_IA32_EMULATION=y
and the personality should be set correctly to linux32
in /etc/vservers/<guest>/personality (to verify, check
with uname -a inside the guest).
