I'd recommend openvz (http://openvz.org). It is based on redhat kernels
are has proved to be very reliable and stable for me on centos 4.4. The
Centos box does a swag of tasks, including,

openvz kernel (complete with virtual DMZ)
Vmware server
NFS server
SMB Server
courier imap (with mysql auth)
postfix (with virtual domains and mysql lookups)
squid cache
Fedora Directory Server

and it never misses a beat.
