Description Federico Simoncelli 2011-05-12 08:36:19 UTC 
Description of problem:
Most of libvirt domain-specific calls are blocking during a qemu migration.

Version-Release number of selected component (if applicable):
libvirt-0.9.1

Steps to Reproduce:
1. define a vm
2. migrate the vm to a different host
3. during the migration execute domblkstat/domblkinfo
  
Actual results:
The domblkstat/domblkinfo calls are blocked until migration completes.

Expected results:
The domblkstat/domblkinfo calls should return the correct values also during migration.

Since RHEL 6.1 External Beta has begun, and this bug remains
unresolved, it has been rejected as it is not proposed as
exception or blocker.

Red Hat invites you to ask your support representative to
propose this request, if appropriate and relevant, in the
next release of Red Hat Enterprise Linux.
