Introduce functions to read and write the state of the VM in xenstore.
This basically creates a new management interface for QEMU via the
xenstore.
Our management interface is QMP. If you want to maintain compatibility,
you'll need to write a QMP -> xenstore daemon that maps events
appropriately.
This would belong in xl/libxl.
Yes, but considering that we don't want a xenstore-based management
interface I would gladly do without the compatibility daemon.
We'll try to reduce all the xenstore interaction to the bare minimum,
and use QMP everywhere else.
Yes, I was just pointing out that you don't need a new compatibility
daemon. Since xl is already daemonizing itself to handle on_crash and
friends, it could also set up all the watches it cares about, and
convert them to QMP commands. It's all more code that needs to be
written of course, and boring stuff even. :)
