Hi Wen,
Thank you very much.
Here are my versoins:
[cloudadmin@test2 ~]$ virsh version
Compiled against library: libvir 0.8.1
Using library: libvir 0.8.1
Using API: QEMU 0.8.1
Running hypervisor: QEMU 0.12.1
I use the same version of libvirt, and still can not reproduce this bug.
[cloudadmin@test2 ~]$ cat /etc/redhat-release
Red Hat Enterprise Linux Server release 6.0 (Santiago)
[cloudadmin@test2 ~]$ uname -a
Linux test2 2.6.32-71.el6.x86_64 #1 SMP Wed Sep 1 01:33:01 EDT 2010 x86_64 x86_64 x86_64
GNU/Linux
Could you please post the "virsh dumpxml" result of the VM after the vdb is
attached?
