libvirt users - Dec 2015 - Re: Destroy autostarted network on shutdown

Hi all,

I just ran into problem properly stopping a network. I have defined a
network and network hook script to accomplish some preparations and
cleanup. Testing my configuration (virsh net-start and virsh
net-destroy) was successfully.

Now I wanted to automate the lifecycle. Unfortunately I realized that an
autostarted network has to be persistent and thus will not be destroyed
(even if the host gets shutdown). As it won't be destroyed, my cleanup
doesn't get executed and I run into trouble.

What would be the preferred way to implement an autostarting and
autostopping network?

Thanks,
Jan

autostarting (and autostopping) based on what event?

Based on start/shutdown of the host or starting/stopping libvirtd. I
just wrote a script to start with systemd but as there is that autostart
functionality in libvirtd this might not be the best solution.
