Re: [Xen-devel] Re: [PATCH]: kexec: framework and i386

Hi, Horms and Mark

This is good work!
It is very necessary for debugging hypervisor or domain0.
I'm not clear at some points.

1. Is this feature available on uni-processor machine?
2. Could you explain more detail usage?

Mark, what do you think about this kdump implementation?

Best Regards,

Akio Takebe
