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.
