[Qemu-devel] [PATCH] runstate: do not discard runstate changes when paused

[Paolo Bonzini <pbonzini@redhat.com>]

Trying to migrate a paused machine fails.  The reason is that
the RSTATE_PRE_MIGRATE is reached with vm_stop, and this
transition is eaten when the vm is already paused.  This patch
fixes the problem by always going through runstate_set and
always notifying the new state.
