kexec is a system call that implements the ability to shutdown your
current kernel, and to start another kernel. It is like a reboot

hmmm why is kexec incompatible with xen? Don't you want to support crash
dumps from guests?

There are kexec patches for Xen which haven't yet been merged into our tree. Even without that we can take coredumps of guests from the control VM, without the guest's active involvement.
