Description of problem:
shutdown event options "on_crash" in xm domain config does not work for all Windows guests.

Version:
xen-3.0.3-142.el5

Steps of Reproduce:
1. change the xm domain config options:
on_crash, with values: destroy, restart, preserve, rename-restart
respectively.
2. create a windows guest.
3. trigger the guest crash by send the SysRq key to guest:
#xm sysrq $domain B

Actual results:
1. When mark "Automatically restart" checkbox in guest
("System Properites" > "Advanced" -> "Startup and Recovery Settings"> "System failure"), the guest will reboot no matter which values in xmdomain config file setup.
when it is not mark, the guest will hang after crash.

Expected results:
1. The guest should response to on_crash option.

Additional info:
1. Also try to make windows guest crash in another way, we crash the windows XP guest inside the windows using the method in bug 861273, and get same result.

2. as xen source code show:
/$xen_source/tools/xenstat/libxenstat/src/xenstat.c
unsigned int xenstat_domain_crashed(xenstat_domain * domain) {
return ((domain->state & DOMFLAGS_SHUTDOWN) DOMFLAGS_SHUTDOWN)
&& (((domain->state >> DOMFLAGS_SHUTDOWNSHIFT)
& DOMFLAGS_SHUTDOWNMASK) SHUTDOWN_crash);
}
This may be a problem caused by different domain info standard between linux guest and windows guest.

3. During the late phase of Xen, this is a low priority task, may be not repaired, but we still think it is good to be record the problem.

4.The issue is already discussed in upstream, see link:
