I'm interested in moving some research prototypes from Xen to KVM, but
there are a few esoteric features I'd need to do this.
First is an efficient mechanism for direct VM-to-VM sockets...something
that bypasses the protocol stack and minimizes overhead. Xen has
XenSocket, XenLoop, and others. I found a few mentions of this idea
dating back to 2006*, mostly saying that a few people have done
something like this as a one-off, but nothing official has been
released. I haven't found anything like this more recently, though.
Has there been any progress on this front? Ideally, I'd want a
character device or a special program that acts as a fast pipe to a
different VM.
Second, what about inter-VM shared memory?
Apologies if I'm missing some well known doc...I search around google &
the wiki to no avail.
Thanks,
Tyler Bletsch
