BSD Jails, a Better Virtual Server?

gManZboy writes "Poul-Henning Kamp, a FreeBSD committer, has an article up about BSD Jails as part of Queue's special report on virtual machines. He describes BSD's interesting 'semi-permeable' approach to VMs, and the importance of security in VM architectures. The article is co-written by Robert Watson, a DARPA principal investigator in the Host Intrusion Protection (HIP) Research Group at McAfee Research."
