[Qemu-devel] [PATCH v3 0/3] virtio-balloon: Don't wait indefinitely for guest response

[Amit Shah <amit.shah@redhat.com>]

Since I didn't get negative reactions to the patch I posted yesterday,
here's the complete series. It adds a qerror message that mentions the
machine is stopped or the guest is slow to respond, so the stats
should be assumed to be old.

The error report is sent out before the stats, I don't think we do
that for any other command. libvirt should be prepared to handle
this. If not, please suggest a better alternative.

Differences from v2:
- Add a timeout for uncooperative/hung guests
- Add an qerror message for letting users/management know of guest
  stopped status.

Amit Shah (3):
  balloon: Don't try fetching info if guest is unresponsive
  qerror: Add a new MACHINE_STOPPED error message
  balloon: Don't try fetching info if machine is stopped
