Changing VM Settings when you have an attached pass through device (such as a GPU) causes the XML to get "corrupted"

Support,

I was running unraid 6.12.13 with GPU pass through to a Windows 11 VM.

I read in the 6.12.12 update notes that we should be using virtio-net instead of virtio for the network interface due to a known performance issue.

I did that and then started the VM again and the GPU pass through stopped working.

I had to create a new VM with all the same settings and re-attach to the existing vdisk image to get running again.

I think something is corrupting the QEMU configs.  I notice the index="" lines are getting out of order.

Attached is the Windows 11 - BlueIris - Rebuild.xml (the working XML from /etc/libvert/qemu) and the "corrupted" XML that no longer allowed for GPU passthrough (Windows 11 - Blueiris.xml)

I should be able to repro this for you as many times as you wish by merely changing the NIC from "virtio" to "virtio-net" and vice versa if you want...
