I wanted to know how Xen-ARM for A15 will address following concerns:
- How will Xen-ARM for A15 support legacy guest environment like ARMv5 or ARMv6 ?
- What if my Cortex-A15 board does not have a GIC with virtualization support ?
Best Regards,
Anup Patel

Do you have a pointer to the kernel sources for the Linux guest?
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.
