Thinking about later RPM upgrades I think we need to think about
whether it
will be possible to restart the libvirt_qemud while guests & networks are
running. There's a couple of issues:
- We do waitpid() to cleanup qemu & dnsmasq processes when we stop domains
& networks, or to detect when they crash. For the former, we could may
they daemons to avoid waitpid() cleanup, but we'd still need waitpid to
be able to detect shutdowns. There is also the issue of enumerating
running instances.
Maybe I'm missing something big here, but how would libvirt_qemud regain
connections to the running qemu monitor ptys?
