[Xen-devel] Re: [RFC, PATCH 0/24] VMI i386 Linux virtualization interface proposal

I agree with Zach here, the Xen hypervisor <-> kernel interface is
not very nice.  This proposal seems like a step forward althogh it'll
probably need to go through a few iterations.  Without and actually
useable opensource hypevisor reference implementation it's totally
unacceptable, though.

Which is why our top priority is getting VMI Linux to run on Xen. The churn rate on both ends has been very high, and we really wanted to release our patches with Xen support, but we also didn't want to wait some unknown number of weeks more to release them - and we're actually looking for volunteers to help with the port if anyone is interested.

What we are hoping for, in the end, is a Linux kernel with a clean virtualization interface, that is maintainable, does not slow hypervisor exploitation of new technologies, still offers all of the same performance advantages, works for the open source community, and allows hypervisor vendors of many creeds to benefit from cross-kernel binary compatibility.
