[Patch][RFC] Support "xm dump" (is Re: [Xen-devel] Re: [Patch] Enable "sysrq c" handler for domU coredump)

[Akio Takebe <takebe_akio@xxxxxxxxxxxxxx>]

Hi, Keir and Horms

This patch is sample patch.
I make "xm dump" command with dom0_ops.
xc_domain_dump() only call __domain_crash().
After __domain_crash(), xend start dumpcore 
because shutdown status is crash.
(When enabel-dump in xend-cofig.sxp is yes)

The xm dump usage is below.
1. vi /etc/xen/xend-config.sxp
   (enable-dump yes)
2. xend start
3. xm create domU
4. xm dump domU
5. coredump is created in /var/xen/dump/

I think this way can probably dump both nonHVM and HVM domain's core.
But I tested only nonHVM domain (because I don't have HVM machine).

How about this implementation?
