[libvirt] [PATCH] Fix warning about unsupported cookie flags in QEMU driver

[Daniel P. Berrange]

From: "Daniel P. Berrange" <berrange at redhat.com>

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.
