I tried. It invalidated the cache of the block device after migration.
Again: all you can do is use O_DIRECT in the guest.I don't understand what you mean.
So, here, we can use a new cache for the block device after migration.
Probably not.
Is it right? I can implement a simple block driver in block/ directory.
