Oh!! I'm so sorry Jan Beulich.
It is my first time to use this mailing list.
Please understand my fault, this time only.

Anyway, as you mentioned, I added below line in '/etc/default/grub' file
and reboot:
> GRUB_CMDLINE_XEN="crashkernel=384M-:256M@64M"
Then,
1. I cannot see anything when I type "grep -i crash /proc/iomem"
2. I can see kernel log of Xen hypervisor when I type "sudo xl dmesg | grep
-i crash":
(XEN) Command line: placeholder crashkernel=384M-:256M@64M

I suppose a 'crashkernel' cmdline option of either Xen hypervisor or Dom0
kernel can be enabled.
I know it is quite difficult to advise some problems online but, could you
give me a piece of hint?

Sincerely,
