Re: [libvirt] [PATCH/RFC] Introduce VIR_MIGRATE_FORCE flag to allow for risky migration

Hi,
Migration will be disallowed when the vm uses host devices or has
snapshots (qemuMigrationIsAllowed)[1]. Would it make sense to introduce
a VIR_MIGRATE_FORCE similar to VIR_REVERT_FORCE here? We could then
introduce error codes similar to the snapshot case
(VIR_ERR_MIGRATE_RISKY).
I'm not sure this will actually work out in practice because QEMU
itself also checks some of these scenarios and blocks them. So even
if libvirt didn't check, the user still wouldnt' be able to force
it to migrate.
