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?

Thanks in advance.

I try to reproduce this bug with upstream libvirt and qemu, but it works fine to me:
# virsh attach-disk RHEL6RC /var/lib/libvirt/images/test3.img vdb --driver file --subdriver qcow2 Disk attached successfully
# virsh detach-disk RHEL6RC vdb Disk detached successfully
What is version of libvirt and qemu that you use?
But if I tried to remove the vda which uses qemu as driver name it would work. [cloudadmin@test2 ~]$ virsh detach-disk one-52 vda Disk detached successfully
I also tried with raw disks to attach/detach and saw the same problems.
Thank you very much. Shi
