Subject: [PATCH] xen: reset creation_finished flag on soft reset
Date: Fri,  1 Sep 2017 11:11:28 +0200	[thread overview]
Message-ID: <20170901091128.21945-1-vkuznets@redhat.com> (raw)

C/s e7dabe5 ("x86/hvm: don't unconditionally create a default ioreq
server") broke soft reset when QEMU traditional is being used. During
soft reset QEMU is relaunched and default ioreq server needs to be
re-created upon first HVM_PARAM_*IOREQ_* request. The flag will be
set back to 'true' when toolstack unpauses the domain, just like after
normal creation.
