[7.0.1] XML Breaks when adding a new VirtioFS Mount

By mackid1993

  • Minor

In my setup I have two virtual NICs (one is just bound to a VLAN br0.2, the other is the main br0) and then all of my VirtioFS shares. I've found that when I set up my Windows VM and use it for a while and then need to maybe pass an additional VirtioFS share through to the VM, the main br0 NIC totally breaks and gets a 169.254 IP address. The only way I can fix it is by deleting the entire template and re-creating from scratch. It's been happening for quite a while. My full XML of the fresh VM is below. The only manual changes I make are changing </nosharepages> to </hugepages> and adding hotplug='off' to the pcie root ports.
