I just happened across this message when going through the backlog and
noticed that I forgot to add "--config" to the above commandline -
without --config, the new entry will only survive until the network is
destroyed (e.g. the host is rebooted), after which it will be lost.
Assuming you've already added several hosts without using --config, you
can transfer them into the permanent network config like this:
virsh net-dumpxml MyGuest
....
virsh net-edit MyGuest
[cut-paste the <host> lines from the dumpxml output into the
configuration file]
Sorry for the omission (and any surprises it may have caused).
