Noticed by comparing the xml generated by virDomainSave with the

Sending this now, to get review started, but I still have some
more fixing to do - right now, active domains still include:
+<seclabel type='dynamic' model='selinux' relabel='yes'/>
which is not present on reparse, but I'm too tired to find out why.
I know the feeling :-)
So does it turn out that this is important, or not?

It's kind of bothersome that use of this magic device name prefix isn't
self-contained in domain_conf.c (or somewhere else). Perhaps the string
could be defined in domain_conf.h, then used here and in qemu_command.c
(is it used any place else?).
Aside from that bit of ugliness, ACK. (And I could live with this. at
least temporarily, as well, although making all the places work off a
single string constant might hypothetically save someone lots of
frustration in some uncharted future.)
