[Qemu-devel] [PATCH 0/3] Introduce a new --only-migratable option |
Date: |

This series adds a new command line option "--only-migratable" which will only
allow addition of those devices to a QEMU instance which are migratable and do
not abruptly fail QEMU after migration.
Patch 1 adds the new option "-only-migratable".
Patch 2 adds compatibility for various "device adding" options for both via
command line and hotplug methods.
Patch 3 handles the special case of devices which become unmigratable
dynamically
by making call to "migrate_add_blocker". Here we fail the particular action of
the
device which results in an unmigratable VM.
Eg: 9pfs fails to mount the filesystem.
Ashijeet Acharya (3):
migration: Add a new option to enable only-migratable
migration: Allow "device add" options to only add migratable devices
migration: disallow migrate_add_blocker during migration
