libvirt-bin should emit net-device-up and net-device-down

[Scott Moser]

I was trying to create an upstart job that would occur when a libvirt network became available:
$ cat /etc/init/maas-dhcp-server-restart.conf
description "restart dhcpd"
start on net-device-up INTERFACE=maasbr0
task

script
 stop maas-dhcp-server
 start maas-dhcp-server
end script
EOF

This didn't work. as libvirt does not emit 'net-device-up' events. Those are only emitted by network manager and devices in /etc/network/interfaces.

It seems possibly useful to have libvirt do that also.

Thanks for submitting this bug. I agree this should be done.

Given that we are quite late in the quantal cycle, how important is this feature to your deliverables? Do we need to ask for an FFE for quantal, or can it wait until after release?

I think this is fine for 'R'.
