OpenVZ ~ Ubuntu kernel
I am fairly new to OpenVZ although I have played with it on Centos. I really like OpenVZ, it seems fairly straight forward and "containers" or guests are light weight and easy to deploy. Backups are much smaller the saving a 5 Gb VMWare disk ....
I have been waiting for OpenVZ to be ported to Ubuntu (I seem to spend a lot of time on Ubuntu).
Well, it is here and they have ported OpenVZ to current kernels
Previous kernels are broken :(
To use OpenVZ install linux-image-2.6.24-19-openvz from proposed:
I did not install more then the OpenVZ kernel + restricted modules (linux-restricted-modules) + headers (linux-headers) from proposed...
There is a nice wiki page specific to Ubuntu here:
The wiki page demonstrates how to make an Ubuntu template & covers host configuration as well as upstart in the guests.
So far I am running OpenVZ on a 64 bit host with no problems. I have not tested 32 bit hosts, but they are reported as working on Launchpad.
Next stop -> learning a little more about managing containers (back up, setting limits on memory / size, etc).
Either set an alias vzctl='sudo vzctl' or start a root shell with sudo -i
Networking Tip : No need for making a bridge on the host, just set an IP address with
vzctl set --ipaddress 192.168.1.xx -save
vzctl set --nameserver 192.168.1.1 --save
viola, container now has private ip address and internet access.
