Simply re-define the nwfilter in question using virsh nwfilter-define.
Any VMs using that filter will automatically update.

I've run into an issue here that I thought you might have some insight
on.
I can't seem to "re-define" a nwfilter. I must first 'virsh
nwfilter-undefine' then 'virsh nwfilter-define', or else use 'virsh
nwfilter-edit'. The problem being, I cannot use nwfilter-edit from a
script :/
My real problem is that if I want to add to and/or adjust a filter for a
VM, I basically have to call 'virsh update-device ...' which
unfortunately leaves the VM wide-open for a short period of time, which
is very undesirable.
I wonder if there's a way to edit the nwfilter _without_ libvirt having
to drop the filter for the VM before applying any changes.
