[RFC] [PATCH 0/4][IA64][HVM] Windows 2003 server crashdump suppprt

[Masaki Kanno]

Hi all,

These patches are able to collect a crashdump of Windows 2003 
server on HVM domain on ia64.

In the ia64 machine, there is an INIT switch. By pushing the 
INIT switch, an INIT interruption is generated. The INIT 
interruption triggers off when the Windows 2003 server collects 
the crashdump.

Currently, we don't provide a virtual INIT switch. Therefore, 
Windows 2003 server on HVM domain is not able to collect the 
crashdump. We provide a new xm command as the virtual INIT 
switch. 

The new xm command: xm os-init <Domain>
