One-line format should work fine with Trixie, but as the “new” deb822 format has been supported since Debian Jessie, it should be usable on most installs.

Hello,

I have a setup with routers (running Debian Bookworm) that need more interfaces than the maximum allowed number of vifs so the VM has one vif and VLAN untagging is done inside it.
As no IPs were detected by the traditional xen tools, I switched to the new, Rust ones, but they fail to detect IPs too

I think it is caused by the lack of /sys/class/net/enX0.*/device/devtype files, despite a few enX0.* interfaces (and folders) and /sys/class/net/enX0/device/devtype (containing vif, as expected) exist.

Should I create an issue directly in the Gitlab project, or comment the partially-related one for SR-IOV support?
