Some Debian GNU/Linux releases do not contain any official openvz Linux kernel packages. This is the reason why this Debian kernel package archive exists.
Squeeze release provided an openvz patched kernel so they are not in this archive.
Lenny release provided an openvz patched kernel so they are not in this archive.
A more convenient way to download the kernels are by using the apt repository.
The main contact of this archive is Ola Lundqvist <firstname.lastname@example.org>.
If you want to report bugs, do that in bugzilla.openvz.org, not to the main contact.
