hi everybody
in my libvirtd I use bridge with route forward mode,
Problem for me is dhcrelay.service on host which is starting before
libvirtd thus not listening on libvirt interface.
OS is RHEL7.
I wonder if you know how to fix it, besides restarting dhcrelay that is.
You could make that happen automatically with a libvirt "network hook":
http://libvirt.org/hooks.html
You would want to create a hook script in /etc/libvirt/hooks/network
that takes action (restarts dhcrelay) when $1 is the network in
question, and $2 is "started" (you may also want to take action when $2
is "stopped" just for symmetry). You'll be able to learn the name of the
bridge device by examining the XML of the network that your script will
receive on stdin. Searching for "network" on the above page will give
more details about what is possible.
