[Xen-devel] [PATCH] Fix xm dump-core for clustering systems

[Masaki Kanno <kanno.masaki@xxxxxxxxxxxxxx>]

Hi,

When a hang-up of a guest OS in a clustering system is occurred, I'd 
like to do fail-over to another in the clustering system, and collect 
a core dump of the guest OS by xm dump-core command with crash option. 
Then I'd like to destroy the guest domain after collecting the core 
dump of the guest OS. 
However, a processing of xm dump-core command destroys the guest domain 
after unpausing the guest domain. For the unpause, the guest OS might 
access disks after fail-over. 

I'd like to remove the possibility by this patch.  The patch gives 
higher priority to domain destructions by crash option than domain 
unpauses.

Best regards,
