Description Paolo Bonzini 2012-04-06 13:28:17 UTC
Description of problem:
The virtio-scsi migration format is not ready for multiqueue.  An extremely simple patch would avoid several headaches in RHEL7 time.

Comment 4 daiwei 2012-05-04 03:27:13 UTC
Verified this issue with steps and environment as follows:
# rpm -q qemu-kvm-rhev
 qemu-kvm-rhev-0.12.1.2-2.287.el6.x86_64

 1. Migrate single guest with two disks 5 times, both guest and host running well.

 2. Migrate three guests in parallelly 5 times, both guests and host running well.


So,this bug has been fixed.
