−	~~OpenVZ consists of a kernel, user-level tools, and VE templates.~~
−
−	~~This guide tells how to install the kernel and the tools on [http://www.debian.org Debian] and related Distribution like [http://www.ubuntu.com/ Ubuntu].~~
−
−	~~== Requirements ==~~
−
−	~~=== Filesystems ===~~
−	It is recommended to use a separate partition for VEs private directories (by default /var/lib/vz/private/<veid>). The reason why you should do so is that if you wish to use OpenVZ per-VE disk quota, you won't be able to use usual Linux disk quotas on the same partition. Bear in mind, that per-VE quota in this context includes not only pure per-VE quota, but also usual Linux disk quota used in VE, not on [[HN]].
−
−	At least try to avoid using root partition for VEs, because the root user of VE will be able to overcome 5% disk space barrier in some situations. This way HN root partition can be completely filled and it will break the system.
−
−	~~OpenVZ per-VE disk quota is supported only for ext2/ext3 filesystems. So use one of these filesystems (ext3 is recommended) if you need per-VE disk quota.~~
−
−
−	~~=== Repository setup ===~~
−
−	~~At the moment two different repositories are online at http://download.openvz.org :~~

−
