Re: [libvirt] [PATCHv3 18/43] snapshot: prevent migration from stranding snapshot data

Migration is another case of stranding metadata. And since

(qemuDomainMigrateBegin3, qemuDomainMigratePerform3): Add
restriction.
Yuck. I just noticed that this patch adds a migration restriction in
qemu_driver, but we already have migration restriction in _two_ other
places in qemu_migration.c. I'll refactor this to put all migration
restrictions into a single site, under qemuMigrationIsAllowed, to cut
down on the duplication.
