I tried. It invalidated the cache of the block device after migration.
It didn't invalidate anything in the guest, and there's *NO WAY* absolutely for QEMU to influence the cache in the guest.
Again: all you can do is use O_DIRECT in the guest.
So, here, we can use a new cache for the block device after migration.
I don't understand what you mean.
Is it right? I can implement a simple block driver in block/ directory.
Probably not. Paolo
