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?
