Why can't vmware use the Xen interface instead?
We could. But it is our opinion that the Xen interface is
unnecessarily
complicated, without a clean separation between the layer of
interaction
with the hypervisor and the kernel proper. The interface we
propose we
believe is more powerful, and more conducive to performance
optimizations while providing significant advantages - most
specifically, a single binary image that is properly virtualizable on
multiple hypervisors and capable of running on native hardware.
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.
As part of our pre-virtualization work, we developed a virtualization
solution similar to VMI. We support Xen v2 and v3 with high
performance. We added support for the first generation of VMI to our
project, and are currently adding support for the latest VMI patch.
Our work is open source. We'll announce when we finish the VMI updates.
We also experimented with other architectures and found the approach
highly suitable, such as for Itanium.
