Description of problem:
I'm using Milestone 7 on our PRIMEQUEST 580 and 520. I attmpted repeating a
process of creating VTi domain with its console and then shutdown it in
nographic mode. 
The first process succeed but the second process and later are failed with the
following message.

 xenconsole: Could not read tty from store: No such file or directory

And Domain0 sometimes became hang in this process. 

Version-Release number of selected component (if applicable):

Steps to Reproduce:
1.xm create -c <config>
2.xm shutdown <domain>
3.xm create -c <config>
  
Actual results:
After finished the first process, the following message was displayed and the
domian cannot create its console.

Domain0 sometimes becomes hang in this process. 

Expected results:
