We have very few changes to the Linux kernel at the moment (only 3 commits!), just enough to be able to issue hypercalls and start a PV console. A git branch is available here (not ready for submission): git://xenbits.xen.org/people/sstabellini/linux-pvhvm.git arm the branch above is based on git://linux-arm.org/linux-2.6.git arm-lpae, even though guests don't really need lpae support to run on Xen. > Since Xen and KVM are both in an early working state right now, > it would be very nice if we could agree on the guest model to make > sure that it's always possible to run the same kernel in both > (and potentially other future) hypervisors without modifications. Yes, that would be ideal. We don't plan on making many changes other than enabling PV frontends and backends. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
