Fedora VMs erroneously state "Changes pending"

[jonpmyatt]

I have two Fedora VMs (F36, F37) and both of them show "Changes pending" in Cockpit related to network, the message is: "VM needs shutdown - Some configuration changes only take effect after a fresh boot: Network interface". A reboot or shutdown/restart does not make this message go away. I've not made any network changes so I suspect this might be a bug, but I don't really know how to investigate it. Thanks.

Same. Alma Linux

Same here, but is Debian host and Debian guest. Have several VMs, but only this one shows the message.

Virtual Machine Manager GUI does not show any changes pending on this VM.

Hey, do you mind sharing an offline and live XML of any of those VM which has the "Changes pending" label. When the VM is running, you can run virsh dumpxml [vmName] to get and n live XML configuration, and then run virsh dumpxml [vmName] --inactive to get an offline XML configuration

I have this same issue when creating a bridged network so VMs can share interfaces.

The host is Ubuntu and the guests are varying Linux and Windows.

Create a bridge:

ip link add br0 type bridge
ip link set eth0 master br0
ip link set br0 up
ip link set eth0 up

Create a new network for KVM:

<network>
    <name>bridge</name>
    <forward-mode="bridge"/>
    <bridge name="br0"/>
</network>

Attach the network to a VM and observe the following: Shutdown, restart, recreate the VM and message persists. The interface is indeed working, on multiple VMs, as it is the only network device attached to each machine.
