[Qemu-devel] [PATCH 1/5] qmp: process system-reset event in paused state

["Denis V. Lunev" <den@openvz.org>]

With pvpanic or HyperV panic devices could be moved into the paused state
with ' <on_crash>preserve</on_crash>'. In this state VM reacts only to
'virsh destroy' or 'continue'.

'virsh reset' command is usually used to force guest reset. The expectation
of the behavior of this command is that the guest will be force restarted.
This is not true at the moment.

Thus it is quite natural to process 'virh reset' aka qmp_system_reset
this way, i.e. allow to reset the guest. This behavior is similar to
one observed with 'reset' button on real hardware :)
