Re: [Xen-devel] [PATCH v2 01/11] kexec: introduce kexec_ops struct

["H. Peter Anvin" <hpa@xxxxxxxxx>]

The other thing that should be considered here is how utterly 
preposterous the notion of doing in-guest crash dumping is in a system 
that contains a hypervisor.  The reason for kdump is that on bare metal 
there are no other options, but in a hypervisor system the right thing 
should be for the hypervisor to do the dump (possibly spawning a clean 
I/O domain if the I/O domain is necessary to access the media.)
There is absolutely no reason to have a crashkernel sitting around in 
each guest, consuming memory, and possibly get corrupt.
