Most VMs libvirt knows how to launch will have qemu network config like:
-netdev $NETDEV_OPTS,id=netdev1 -device e1000,id=netdev1
However for machine types with built-in platform network devices, we
currently do:
-net nic,model=e1000,vlan=1 -net $NETDEV_OPTS,vlan=1
However for the platform case, all qemu versions we support can do:
-netdev $NETDEV_OPTS,id=netdev1 -net nic,model=e1000,netdev=netdev1
Which simplifies our code, and is more future proof as qemu has
deprecated the vlan= option. This series switches to the netdev=
method, and performs some cleanups in related code.
Thanks,
Cole

Nit pick, I prefer s/qemu: command:/qemu_command/ in $SUBJ, but at the
same time don't care that much. It's a matter of preference after all.

Might as well drop this. Looking into the future at 5/6 and you're doing
just that. My suggestion is to merge 5/6 into this one, but whatever you
