Linux vserver shares the kernel between the various virtual hosts, a
little like BSD jails. There are restrictions on what one can do: not
even root can modify network interfaces or even create a node (using
mknod) or mount a filesystem, so breaking out of the virtualhost is
pretty hard. No guarantees, but to answer your question, yes, it does
protect the host OS.
