Sorry about the confusion, I don't have any domU guest

My grub menu.lst is,
kernel /boot/xen.gz watchdog=0 dom0_mem=1024M
lowmem_emergency_pool=16M crashkernel=128M@32M nmi=dom0
module /boot/vmlinuz-2.6.27.42-0.1.1.xs5.6.0.44.111158xen ro
ramdisk_size=250000 nmi_watchdog=0 xencons=off console=rcons0
module /boot/initrd-5.6.0-31188p.img
xen.gz is 64 bit one, while dom0 kernel is 32bit...
I am using echo c > /proc/sysrq-trigger to generate the kernel dump.
When I tried to open the kernel dump,
[debugger@crash HV_crash]$ crash32 vmlinux-2.6.27
vmcore-2010-09-02-22-30-38
crash32 5.0.3
……………….
This program has absolutely no warranty. Enter "help warranty" for

Well, for starters, the crash utility must match the vmlinux file type,
i.e., you should be using the 32-bit version.
What is the output of:
# readelf -a vmcore-010-09-02-22-30-38
