[RFC PATCH 0/7] Fix issue when storage migration is requested but there are no disks to migrate
In certain weird cases and due to very crusty code we'd instruct qemu to
migrate storage using the old style storage migration when there wasn't
anything to migrate. This was caused by a recent refactor.
Note that the series is RFC as I didn't really test it yet, but feel
free to provide feedback.
Peter Krempa (7):
util: xml: Introduce virXMLFormatElementEmpty
qemuMigrationCookieNBDXMLFormat: Format empty <nbd/> element
qemuMigrationSrcNBDStorageCopy: Return error code on error
qemuMigrationSrcNBDStorageCopy: Don't pass migrate_flags
qemuMigrationSrcRun: Sanitize setting of cookieFlags and migrate_flags
on storage migration
qemuMigrationSrcRun: Don't attempt any storage migration if no disks
will be migrated
qemuMigrationSrcBeginPhase: Don't offer 'nbd' in cookie if there are
no disks to migrate
