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 Lili Zhu 2023-04-17 10:35:20 UTC 
Description of problem:
Plug watchdog devices with different action from existing watchdog devices should be failed

Version-Release number of selected component (if applicable):
libvirt-9.2.0-1.el9.x86_64
qemu-kvm-7.2.0-14.el9_2.x86_64

How reproducible:
100%

Steps to Reproduce:
1. prepare a guest with a watchdog device
# virsh dumpxml avocado-vt-vm1 --xpath //watchdog
<watchdog model="itco" action="reset">
  <alias name="watchdog0"/>
</watchdog>

2. prepare a watchdog device to be plugged
# cat watchdog.xml
<watchdog model='i6300esb' action='shutdown'/>

3. attach the watchdog device
# virsh attach-device avocado-vt-vm1 watchdog.xml --config --live 
Device attached successfully

4. check the guest xml
# virsh dumpxml avocado-vt-vm1 --xpath //watchdog
<watchdog model="itco" action="reset">
  <alias name="watchdog0"/>
</watchdog>
<watchdog model="i6300esb" action="shutdown">
  <alias name="watchdog1"/>
  <address type="pci" domain="0x0000" bus="0x10" slot="0x01" function="0x0"/>
</watchdog>

5. destroy the guest and start it again
# virsh start rhel9.3 
error: Failed to start domain 'rhel9.3'
error: unsupported configuration: watchdogs with different actions are not supported with this QEMU binary

Actual results:
Watchdog devices with different action from existing watchdog devices can be plugged

Expected results:
Watchdog devices of different action with the existing watchdog devices can not be plugged
