Re: [Xen-devel] [PATCH] Domain core-dumping fixes
Hi John,

The reset option cuts down the number of operations for users.
Without the reset option:
1) xm dump-core --crash vm1
2) xm create/start vm1
With the reset option:
1) xm dump-core --reset vm1
If a crashed guest works between unpause and reset,
then the guest system may corrupt.
So we want to reset the crashed guest before unpause.
If we cannot do that, the reset option is worthless.
May I remove the reset option from xm dump-core command?

I cannot complain.
Should we not add options for clients anymore?
Will anyone improve server/SrvDomain.py?
Best regards,
