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


From: Ashijeet Acharya
Subject: [Qemu-devel] [PATCH 0/3] Introduce a new --only-migratable option
Date: Thu, 15 Dec 2016 00:36:59 +0530

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
