GPU migration is not working #207

Closed oryair1 closed 2 years ago

Hi, I am using both a linux version and a qemu version which contain the code for the migration but I am still getting: Error: VFIO device doesn't support migration When I am trying to create a snapshot with qemu

After further investigating, I see in QEMU that the call to vfio_get_dev_region_info inside the function vfio_migration_probe fails and can't find the VFIO_REGION_TYPE_MIGRATION device region. That is strange, because in issue #166 @TerrenceXu mentions that Intel GVT-G is migratable.

Then how come is that happening?
