Oh, I see the problem: the vlan setting is inherited from the network, it's not part of the interface XML and yet, libvirt clears the the vlan setting. Issue migration from Bugzilla to Jira is in process at this time. This will be the last message in Jira copied from the Bugzilla bug. This BZ has been automatically migrated to the issues.redhat.com Red Hat Issue Tracker. All future work related to this report will be managed there. Due to differences in account names between systems, some fields were not replicated. Be sure to add yourself to Jira issue's "Watchers" field to continue receiving updates and add others to the "Need Info From" field to continue requesting information. To find the migrated issue, look in the "Links" section for a direct link to the new issue location. The issue key will have an icon of 2 footprints next to it, and begin with "RHEL-" followed by an integer. You can also find this issue by visiting https://issues.redhat.com/issues/?jql= and searching the "Bugzilla Bug" field for this BZ's number, e.g. a search like: "Bugzilla Bug" = 1234567 In the event you have trouble locating or viewing this issue, you can file an issue by sending mail to rh-issues.

Description of problem: Update portgroup of ovs interface, the port tag is cleared unexpectedly. Version-Release number of selected component (if applicable): libvirt-8.5.0-6.el9.x86_64 openvswitch2.15-2.15.0-70.el9fdp.x86_64 How reproducible: 100% Steps to Reproduce: 1. Create an openvswitch bridge # ovs-vsctl show ce606951-de6b-4515-9280-44b2a6766a57 Bridge "ovsbr0" Port "ovsbr0" Interface "ovsbr0" type: internal Port "eno8303" Interface "eno8303" ovs_version: "2.15.6" 2. Create an openvswitch network: <network> <name>ovs-net</name> <uuid>1546c287-e22f-41c5-8eef-12ccb8a54af6</uuid> <forward mode='bridge'/> <bridge name='ovsbr0'/> <vlan trunk='yes'> <tag id='42' nativeMode='untagged'/> <tag id='47'/> </vlan> <virtualport type='openvswitch'> <parameters interfaceid='09b11c53-8b5c-4eeb-8f00-d84eaa0aaa4f'/> </virtualport> <portgroup name='dontpanic'> <vlan> <tag id='42'/> </vlan> </portgroup> </network> 3. Start a vm 4. Attach a openvswitch interface to vm: # virsh attach-interface vm111 --type network --source ovs-net --model virtio Interface attached successfully # virsh dumpxml vm111 --xpath //interface <interface type="bridge"> <mac address="52:54:00:07:7e:14"/> <source network="ovs-net" portid="555b1703-8f01-4f74-b15d-674b0c5e695a" bridge="ovsbr0"/> <vlan trunk="yes"> <tag id="42" nativeMode="untagged"/> <tag id="47"/> </vlan> <virtualport type="openvswitch"> <parameters interfaceid="09b11c53-8b5c-4eeb-8f00-d84eaa0aaa4f"/> </virtualport> <target dev="vnet3"/> <model type="virtio"/> <alias name="net0"/> <address type="pci" domain="0x0000" bus="0x01" slot="0x00" function="0x0"/> </interface> # ovs-vsctl show ce606951-de6b-4515-9280-44b2a6766a57 Bridge ovsbr0 Port ovsbr0 Interface ovsbr0 type: internal Port vnet3 tag: 42 trunks: [42, 47] Interface vnet3 Port eno8303 Interface eno8303 ovs_version: "2.15.6" 5. Update interface portgroup: # cat ovs-inc.xml <interface type="network"> <mac address="52:54:00:e9:a0:ba"/> <source network='ovs-net' portgroup='dontpanic'/> <model type="virtio"/> <address type="pci" domain="0x0000" bus="0x01" slot="0x00" function="0x0"/> </interface> # virsh update-device vm111 ovs-inc.xml Device updated successfully 6. Check the updated interface: # virsh dumpxml vm111 --xpath //interface <interface type="bridge"> <mac address="52:54:00:e9:a0:ba"/> <source network="ovs-net" portgroup="dontpanic" portid="a31b4f86-cfe7-4951-b23a-1f6465df7345" bridge="ovsbr0"/> <vlan> <tag id="42"/> </vlan> <virtualport type="openvswitch"> <parameters interfaceid="09b11c53-8b5c-4eeb-8f00-d84eaa0aaa4f"/> </virtualport> <target dev="vnet4"/> <model type="virtio"/> <alias name="net0"/> <address type="pci" domain="0x0000" bus="0x01" slot="0x00" function="0x0"/> </interface> # ovs-vsctl show ce606951-de6b-4515-9280-44b2a6766a57 Bridge ovsbr0 Port ovsbr0 Interface ovsbr0 type: internal Port eno8303 Interface eno8303 Port vnet4 Interface vnet4 ovs_version: "2.15.6" Actual results: When updating interface portgroup, ovs port tag is cleared. Expected results: Updating interface portgroup should fail like: # virsh update-device rhel interface.xml error: Failed to update device from interface.xml error: internal error: Unable to set vlan configuration on port vnet4 Additional info: 1. Check the syslog: ovs-vsctl[286450]: ovs|00001|vsctl|INFO|Called as ovs-vsctl --timeout=5 -- --if-exists clear Port vnet4 tag -- --if-exists clear Port vnet4 trunk -- --if-exists clear Port vnet4 vlan_mode
