Hmm, that's because we're using/developing a Linux distribution which
doesn't have 64-bit support yet. But since the guest will be a
compile-farm for our needs, it's worth trying to run an 64-bit distro on
the host to see the difference, thanks for the tip but how much should
this affect the performance?

Thanks.
