LXC was a preferred choice as it is in the kernel but at the moment it 
is lacking several features mainly migrations and resource management. 
LXC is using cgroups for resource management but it is not as fine 
grained or as easy to administer as openvz resource management.  There 
may have been a few other reasons for the choice but those are the main 
ones I can think of.
