Allows one to run multiple GNU/Linux distributions as virtual hosts. They all share the same kernel, which may be a limitation!
From http://download.openvz.org/kernel/debian/etch/ download
linux-headers-2.6.18-openvz-686_02_i386.deb linux-headers-2.6.18-openvz-amd64_01_amd64.deb linux-image-2.6.18-openvz-686_02_i386.deb linux-image-2.6.18-openvz-amd64_01_amd64.deb
These might only work for etch? (Should be okay for sid)

These are OS templates.
Set up networking. Edit /etc/network/options to set:
(Might need to wajig restart networking - not sure it was necessary.) Then run:
$ sudo sysctl -w net.ipv4.conf.eth0.proxy_arp=1001
Can have this on boot with the following in
up sysctl -w net.ipv4.conf.eth0.proxy_arp=1001 pre-down sysctl -w net.ipv4.conf.eth0.proxy_arp=0
Now create a new host. We’ll give it an id of 1001.
$ sudo mv fedora* /var/lib/vz/template/cache $ sudo vzctl create 1001 --ostemplate fedora-core-5-i386-default Creating VPS private area: /var/lib/vz/private/1001 Performing postcreate actions VPS private area was created $ sudo vzctl set 1001 --ipadd 192.168.0.10 --nameserver 188.8.131.52 --hostname ovz01 --save Saved parameters for VPS 1001 $ sudo vzctl start 1001 14 Jan 07:22:58 gjw@belinos:/var/lib$ sudo vzctl start 1001 Starting VPS ...

To stop the virtual host:
$ sudo vzctl stop 1001 Stopping VPS ... VPS was stopped VPS is unmounted
To remove the virtual host setup:
$ sudo vzctl destroy 1001 Destroying VPS private area: /var/lib/vz/private/1001 VPS private area was destroyed
So now we have Fedora Core running, virtually as a separate machine. But I recall now why I moved to Debian - it is a dog to get packages installed appropriately.
