Maks & I discussed this on IRC and drafted the following text which we believe is ready for inclusion: Debian 6.0 will be the final Debian release to include Linux kernel virtualization featuresets outside of mainline. This means that the OpenVZ and Linux-Vserver featuresets should be considered deprecated, and users should migrate to linux-2.6 upstream merged virtualization solutions like KVM, Linux Containers or Xen.
