Any guidance why and when users would want to enable it?
Is it a good idea to have device-specific capabilities?
Hmm, maybe it's better way to make a parameter for the vhost-user-blk instead
of migration capability?
What do you think?
I think this is a question for the migration maintainers :)
Oops, I missed this email previously..
We discussed similar things with Vladimir on virtio-net. Unless extremely
necessary, we should avoid adding any cap into migration that is relevant
to a specific device. Yes, per-device is better..
Thanks,
Arlight, thanks!
