How reproducible is this bug?:
100%
Steps to reproduce
- start a vm with interface as below with alias setting:
#virsh start vm2 #virsh dumpxml vm2 --xpath //interface <interface type="network"> <mac address="52:54:00:90:88:cc"/> <source network="default" portid="4384b8f7-c370-43f5-a58a-a3f932f37fe1" bridge="virbr0"/> <target dev="vnet8"/> <model type="virtio"/> <driver queues="2"/> <alias name="ua-629187c4-798e-4ad7-9909-0528c92bd534"/> <address type="pci" domain="0x0000" bus="0x01" slot="0x00" function="0x0"/> </interface>
2.Prepare the interface device xml the same as above except deleting the alias setting:
#cat if.xml <interface type="network"> <mac address="52:54:00:90:88:cc"/> <source network="default" portid="afcafd32-21a7-4105-a2c9-e40f15dd69fa" bridge="virbr0"/> <target dev="vnet8"/> <model type="virtio"/> <driver queues="2"/> <address type="pci" domain="0x0000" bus="0x01" slot="0x00" function="0x0"/> </interface>
3.Update the interface of the guest to delete alias setting:
# virsh update-device vm2 if.xml
Device updated successfully
4. Check the interface device of guest, the alias setting still exists:
# virsh dumpxml vm2 --xpath //interface <interface type="network"> <mac address="52:54:00:90:88:cc"/> <source network="default" portid="ddfbc35c-cf8b-4443-9e43-637c9112f5ff" bridge="virbr0"/> <target dev="vnet8"/> <model type="virtio"/> <driver queues="2"/> ***<alias name="ua-629187c4-798e-4ad7-9909-0528c92bd534"/>*** <address type="pci" domain="0x0000" bus="0x01" slot="0x00" function="0x0"/> </interface>
5.The issue also exists when deleting target dev, update device to delete target dev returns successfully but the target dev setting still exists.
Expected results
The update-device command should report error like:
error: Failed to update device from if.xml
error: Operation not supported: cannot modify network device alias setting
Actual results
Live update interface to delete alias or target dev setting succeed but no changes in xml.
