Re: [Xen-devel] Proposal for init/kexec/hotplug format for Xen

I think we will provide a custom protocol for allowing guest kernels
to access the persistent store -- it needn't be very complicated, and
will allow things like basic device bootstrap to be done via the store
without any chicken-and-egg or deadlock problems. Also there may be
security implications in allowing arbitrary guests to make TCP
connections to domain0 (at the very least, there may be possible DoS
attacks) -- of course we allow this by default right now, but we don't
want to make it a requirement of using Xen.
One of the things I'd like to see in the new management tools is a
higher level interdomain communication library. A very useful
abstraction would be a interdomain stream built on top of shared memory
and event channels.
Interdomain streams would be perfect for something like this.
