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.
Description of problem:
guest will paused after do snapshot-revert to a external snapshot and guest's xml have multifunction='on' usb controller.
Version-Release number of selected component (if applicable):
libvirt-0.10.2-41.el6.x86_64
qemu-kvm-rhev-0.12.1.2-2.431.el6.x86_64
How reproducible:
100%
Steps to Reproduce:
1.# virsh dumpxml test6
.....
<disk type='file' device='disk'>
<driver name='qemu' type='qcow2' cache='none'/>
<source file='/var/lib/libvirt/images/test6.img'/>
<target dev='hda' bus='ide'/>
<address type='drive' controller='0' bus='0' target='0' unit='0'/>
</disk>
....
<controller type='usb' index='0' model='ich9-ehci1'>
<alias name='usb0'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x7'/>
</controller>
<controller type='usb' index='0' model='ich9-uhci1'>
<alias name='usb0'/>
<master startport='0'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0' multifunction='on'/>
</controller>
....
2.# virsh snapshot-create-as test6 s8 --memspec file=/tmp/s8.mem --diskspec hda,file=/tmp/s8.img --live
Domain snapshot s8 created
3.# virsh dumpxml test6
<disk type='file' device='disk'>
<driver name='qemu' type='qcow2' cache='none'/>
<source file='/tmp/s8.img'/>
<target dev='hda' bus='ide'/>
<alias name='ide0-0-0'/>
<address type='drive' controller='0' bus='0' target='0' unit='0'/>
</disk>
4.# virsh list --all
Id Name State
----------------------------------------------------
39 test6 running
5.# virsh snapshot-revert test6 s8
error: Requested operation is not valid: the snapshot 's8' does not exist, and was not loaded
6.# virsh list --all
Id Name State
----------------------------------------------------
39 test6 paused
Actual results:
guest status have been changed to paused after snapshot-revert
Expected results:
guest still running and error report should be:
error: unsupported configuration: revert to external disk snapshot not supported yet
