Thread-topic: [Xen-ia64-devel] [PATCH] Allow multiple-time mmap of the privcmddevice
Hi Yamahata /Alex,
 When I configured memory 800M for xen0 and 128M for VTi, I can create VTi to 
EFi with VP_mode, but it couldn't boot to system. I attached screen picture, 
and could you give more tips? :)
Thanks a lot.
