[Qemu-devel] [PATCH v7 08/42] migrate_init: Call from savevm


From: Dr. David Alan Gilbert (git)
Subject: [Qemu-devel] [PATCH v7 08/42] migrate_init: Call from savevm
Date: Tue, 16 Jun 2015 11:26:21 +0100

From: "Dr. David Alan Gilbert" <address@hidden>

Suspend to file is very much like a migrate, and it makes life
easier if we have the Migration state available, so initialise it
in the savevm.c code for suspending.
