[Pacemaker] Ubuntu 10.04.3 LTS and the VirtualDomain RA

Sadly yes. As far as I know my patches did not even make it into the resource-
agents sources. Please do not ask me why.

For the time being you have to patch the RAs manually. Please copy the 
existing RA to a separate directory /usr/lib/ocf/resource.d/myagents and apply 
the patch to that RA. Use the VirtualDomain agent from the provider myagents 
in your configuration. This way your prevent reverting the patches with the 
next update.
