Steps to reproduce
- Start a guest with the virtio model interface device:
# virsh dumpxml 1 --xpath //interface <interface type="network"> <mac address="52:54:00:38:55:56"/> <source network="default" portid="200d3829-8433-498c-8765-6ac8bb84545d" bridge="virbr0"/> <target dev="vnet0"/> <model type="virtio"/> <driver queues="2"/> <alias name="net0"/> <address type="pci" domain="0x0000" bus="0x01" slot="0x00" function="0x0"/> </interface>
2.Prepare a interface xml without model type:
#cat if.xml <interface type="network"> <mac address="52:54:00:38:55:56"/> <source network="default" portid="200d3829-8433-498c-8765-6ac8bb84545d" bridge="virbr0"/> <target dev="vnet0"/> <driver queues="2"/> <alias name="net0"/> <address type="pci" domain="0x0000" bus="0x01" slot="0x00" function="0x0"/> </interface>
3.Update the interface device to delete model type:
# virsh update-device 1 if.xml error: Failed to update device from if.xml error: Operation not supported: cannot modify virtio network device driver attributes
Expected results
Because the default model type of the interface is 'virtio', updating a virtio model interface device to remove the model type should be successful.
Actual results
It reports unclear error info since it did to try to update network device driver attributes actually.
