RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Comment 2 Jiri Denemark 2011-06-09 12:02:14 UTC 
Hmm, it seems drive hotplug went all the way down to HMP passthrough although it should have been handled by __com.redhat_drive_add QMP command. Could you attach libvirtd debug logs of this operation?

Comment 4 weizhang 2011-06-13 01:50:06 UTC 
on libvirt-0.8.7-18.el6.x86_64 , hotplug succeed with no error, so set to regression
Comment 5 Jiri Denemark 2011-06-13 11:45:31 UTC 
Thanks, so __com.redhat_drive_add command was used and succeeded. This a bug in forwardporting libvirt-Support-virtio-disk-hotplug-in-JSON-mode.patch from 6.1.
Comment 6 Jiri Denemark 2011-06-13 12:06:27 UTC 
A fixed version of the patch sent to rhvirt-patches: http://post-office.corp.redhat.com/archives/rhvirt-patches/2011-June/msg00145.html
Comment 7 Daniel Veillard 2011-06-23 03:41:36 UTC 
I apparently missed the patch when building libvirt-0.9.2-1.el6, should be in
next build though !

Reproduced this issue on libvirt-0.9.2-1.el6.x86_64
# virsh attach-disk rhel6 /var/lib/libvirt/images/foo.img vda
error: Failed to attach disk

Tested this issue with:

libvirt-0.9.3-1.el6
qemu-kvm-0.12.1.2-2.167.el6
kernel-2.6.32-164.el6

# virsh attach-disk rhel6 /var/lib/libvirt/images/foo.img vda
Disk attached successfully

#virsh dumpxml rhel6
     .........
    <disk type='block' device='disk'>
      <driver name='qemu' type='raw'/>
      <source dev='/var/lib/libvirt/images/foo.img'/>
      <target dev='vda' bus='virtio'/>
