Subject: Zero-copy block driver?
Date: Sat, 29 Jan 2011 04:55:23 +0100 [thread overview]
Message-ID: <4D438FAB.5000002@gmail.com> (raw)
Hi everyone,
Could you please tell me if it is possible to use a block driver that
completely avoids the guest kernel and copies block data directly
to/from the given buffer in the guest userspace?
If yes, how to activate it? If not... why not? :)
Thanks!
Darko
