For the ARM part: Apart from the issue I found and reported in patch 7/15, the build was successful. I tested the following basics also successfully: -booting a dom0 -booting domUs -networking between guest and dom0 using NAT -stressing hypercall xen_version so, Tested-by: Michal Orzel <michal.or...@arm.com> Cheers, Michal
