Comments on How To Convert Physical Systems And Xen VMs Into OpenVZ Containers (Debian Etch)

How To Convert Physical Systems And Xen VMs Into OpenVZ Containers (Debian Etch) This guide explains how you can convert physical systems (running Debian Etch) or Xen domUs (also running Debian Etch) into an OpenVZ container. This procedure should also work for converting VMware VMs, VirtualBox VMs, or KVM VMs into OpenVZ containers, but I haven't tried this. It should work for other Linux distributions as well, with minor modifications (for example, the network configuration is not located in /etc/network/interfaces if you're not on Debian/Ubuntu).

I prefer to prefix the directories with "/" in the rsync command. It prevents rsync to exclude any files or directory that may contain "dev" or "proc" in the name:

 rsync -arvpz --numeric-ids --exclude /dev --exclude /proc --exclude /tmp ...

 

thanks for the howto!

Thanks for that beautiful Howto. I had some problems and solved them this way:

  mkdir /vz/private/211/tmp

  chmod 777  /vz/private/211/tmp

  mkdir /vz/private/211/var/tmp

  chmod 777  /vz/private/211/var/tmp

  mknod --mode 666 /vz/private/211/dev/random c 1 8

  mknod --mode 666 /vz/private/211/dev/zero c 1 5

  mknod --mode 666 /vz/private/211/dev/null c 1 3

nice day

I found /dev/tty was a normal file, and several things didn't work. It looked like this:

HN:# ls -l /vz/private/221/dev/tty
-rw-r--r-- 1 root root 16 Feb 13 14:42 /vz/private/221/dev/tty

To fix this:

   rm /vz/private/221/dev/tty

   mknod --mode 666 /vz/private/221/dev/tty c 5 0

Now it's a character special file and things are better:

HN:# ls -l /vz/private/221/dev/tty
crw-rw-rw- 1 root root 5, 0 Feb 13 15:55 /vz/private/221/dev/tty

Thanks!

Add the following to the rsync command:   --exclude /sys

later on server2:  mkdir /vz/private/211/sys
