Description Andrew Jones 2009-10-20 15:10:46 UTC 
Description of problem:

Received a message that a domain is in use when attempting to create it, even though the domain isn't in use.

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

Latest 5.4 xen.

How reproducible:

50%

Steps to Reproduce:
1. Use halt command to shutdown a linux vm.
2. Attempt to create the vm with 'xm create -c $VM'
3.
  
Actual results:

# xm create -c raw-64pv
Using config file "/etc/xen/raw-64pv".
Error: VM name 'raw-64pv' already in use by domain 216

Expected results:

vm creates, since it's actually not in use.

Additional info:

If 'xm list' or possibly other xm commands are run before the 'xm create' command, then 'xm create' will succeed.

Regression between 5.4 (xen-3.0.3-94.el5) and xen-3.0.3-95.el5. Raising priority and taking care of it (I think I know where the problem is)...

BTW I can reproduce it almost in 100% cases on -95.el5.
