Summary
- vserver is a UNIX virtualisation system, similar to FreeBSD Jails or Solaris containers
- vserver is orthogonal to system virtualisation, and vserver kernels can happily run inside systems like Xen.
- compatible with Linux 2.4, 2.6, supports virtualising processes, networking, disk (disklimits and quotas), cpu, memory
- works well with firewalling, LVM, NFS, AoE, iSCSI... anything else?
