qemu: Check all watchdogs for iTCO duplicates
Tested this bug with:
libvirt-9.3.0-1.el9.x86_64
1. Prepare a guest with the following xml snippet
<watchdog model='itco' action='reset'>
<alias name='watchdog0'/>
</watchdog>
<watchdog model='itco' action='reset'>
<alias name='watchdog1'/>
</watchdog>
2. define the guest
# virsh define avocado-vt-vm1.xml
error: Failed to define domain from avocado-vt-vm1.xml
error: unsupported configuration: domain can only have one watchdog with model 'itco'
Verified with:
libvirt-9.3.0-1.el9.x86_64
Scenario 1:
1. Prepare a guest with the following xml snippet
<watchdog model='itco' action='reset'>
<alias name='watchdog0'/>
</watchdog>
<watchdog model='itco' action='reset'>
<alias name='watchdog1'/>
</watchdog>
2. define the guest
# virsh define avocado-vt-vm1.xml
error: Failed to define domain from avocado-vt-vm1.xml
error: unsupported configuration: domain can only have one watchdog with model 'itco'
Scenario 2:
1. Prepare a guest, check its xml about watchdog
# virsh dumpxml avocado-vt-vm1 --xpath //watchdog
<watchdog model="itco" action="reset">
<alias name="watchdog0"/>
</watchdog>
2. coldplug a itco watchdog device
# virsh attach-device avocado-vt-vm1 watchdog.xml --config
error: Failed to attach device from watchdog.xml
error: Requested operation is not valid: device is already in the domain configuration
