Depends on the kind of virtualization. As you're on Linux, you could
use OpenVZ: it has similar characteristics as chroot - it just separates
namespaces (eg. network interfaces, pids, etc) and allows different
limits (eg. maxprocs, maxfiles, maxmem, ...) on per-VZ basis.

BTW: my current customer already consolidated multiple formerly
dedicated mysql servers (in mass hosting) onto one metal (now we're
building a system which allows moving individual databases around
in the cluster w/o being visible to the customer ...). The same
should be easily possible w/ PostgreSQL and other RDBM'es.
