[one-users] Using Images

[Javier Fontan]

Hello,

Nice you found the problem!

It is not strange for a VM to be in blocked state. It just means that  
it that specific moment the VM is blocked. It can be blocked because  
it is idling, waiting for IO, other VM is using the processor, etc.  
The most common case is a VM in a machine with just one processor.  
When you issue xm list all the other VM's are in blocked state as  
dom-0 is using the processor in that very moment (executing xm info).  
I hope it clarifies the issue.

Bye
