Log message:
vmd: reorder PCI device assignment to fix Linux network interface numbering
On some recent Linux guests, the virtio network interface is named based
on its PCI slot assignment, eg "enp0s3".
Prior to this change, vmd assigned disks first, meaning if you used a disk
image to install Linux and then removed it after install, the network
interface name would change from "enp0s3" to "enp0s2" (for example). This
broke any autoconfiguration script config files written during the install
and generally led to users just being confused about what was going on.
This change reorders the vmd PCI device assignment to put network
interfaces before disks, as disk devices don't seem to have the same
naming issue. This means the slot for network interfaces won't change.
IMPORTANT NOTE - if you have existing Linux guest VMs, you'll need to
manually fixup your config files (once).
