OVN networking set up by MicroCloud.

Instance log

N/A

Expected behavior

Creating a network twice fails on the second go:

$ lxc network create default --type=ovn network=UPLINK ipv4.address=10.0.2.1/24
Network default created
$ lxc network create default --type=ovn network=UPLINK ipv4.address=10.0.2.1/24
The network already exists
$ echo $?
1

Actual behavior

Creating the network twice appears to succeed:

$ lxc network create default --type=ovn network=UPLINK ipv4.address=10.0.2.1/24
Network default created
$ lxc network create default --type=ovn network=UPLINK ipv4.address=10.0.2.1/24
Network default created

The API response is just wrong:

2026-07-09T18:15:24.424346-05:00 terra lxd.daemon[2962]: time="2026-07-09T18:15:24-05:00" level=warning msg="Failure for operation" class=task description="Creating network" err="The network already exists" operation=019f492a-1c59-7c61-999f-668635bc0b69 project=prod

Steps to reproduce

1. Deploy single-node microcloud; configure only distributed networking with OVN.
2. Create an OVN network twice.

This occurs for other failed actions too:

2026-07-09T18:20:11.558483-05:00 terra lxd.daemon[2962]: time="2026-07-09T18:20:11-05:00" level=warning msg="Failure for operation" class=task description="Updating network" err="Invalid option for network \"UPLINK\" option \"ovn.ingress-mode\"" operation=019f492e-7e0c-73a5-9367-244f7e7ba1c0 project=default

I suspect lxc network isn't handling operation responses correctly.

Information to attach

• Any relevant kernel output (dmesg)
• Instance configuration (lxc config show <instance> --expanded)
• Main daemon log (at /var/log/lxd/lxd.log or /var/snap/lxd/common/lxd/logs/lxd.log)
• If a lxc command fails, output of the command with --debug
• Output of the daemon with --debug (or use lxc monitor while reproducing the issue)
