Actually, a miss.

That line meant "list of enabled hosts: ID=0". At this point I do not 
quite understand what is going on. Why is the VM left in pending state? 
I can force a VM deploy of that VM on the Xen host, which goes its way. 
Could it be due to some memory misinterpretation?

oneadmin at vadmin:/srv/cloud/images/xen$ onehost list

I mean, this is normal for Xen, it gives all available memory to Dom0 
and Dom0 will take that memory and give it to the VM, I've seen messages 
in xend.log stating "baloon driver reducing memory of Dom0". Should I 
manually reduce the memory available to Dom0?

Nix.
