From: "Daniel P. Berrange" <berrange(a)redhat.com&gt; The QEMU migration code unconditionally sets the 'persistent' cookie flag on the source host. The dest host, however, only allows it during parsing if VIR_MIGRATE_PERSIST_DEST was set. Make the source host only set it if this flag is present. Signed-off-by: Daniel P.
