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

Yes. I was only pointing out that I think the persistent store should

that would be that it would be accessible by all domains without any
special supporting software (like a TCP/IP stack).
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.
I think keeping the store in userspace has more advantages (mainly
robustness and extensibility). It sounds like we're all in agreement
though :-)
Yes, I think we are. :-)
