Hi Josh,

I expect multiple VMs will be used for mobile and servers based on Cortex A15.

Hi Sang,
Thanks for your reply. The multiple VMs solution is very useful for
lower CPU and memory boards, but it needs to change Xen vanila
PV-Linux's architecture, as ARM A15 coming up,will the multiple VMs be
popular in future?
