Thanks Dave,<br><br>I had tried another combination: 32 bit Xen kernel with 32 bit Dom0 kernel, but I have the similar issue. The vmcore file is still in 64 bit format. (Our system has a large memory configuration 8GB-192GB), Is there any way I can generate elf32 vmcore file ?<br>

</div>Hmmm -- now that I think about it, it's seems that the crash<br>
utility has never supported dom0 vmcores generated from this<br>
type of Xen hypervisor/dom0 combination.<br>
<br>
Red Hat kernel versions come with the xen.gz and vmlinuz files<br>
packaged together, i.e., both 64-bit or both 32-bit:<br>
<br>
# rpm -qpl kernel-xen-2.6.18-219.el5.x86_64.rpm<br>
/boot/.vmlinuz-2.6.18-219.el5xen.hmac<br>
/boot/System.map-2.6.18-219.el5xen<br>
/boot/config-2.6.18-219.el5xen<br>
/boot/symvers-2.6.18-219.el5xen.gz<br>
/boot/vmlinuz-2.6.18-219.el5xen<br>
/boot/xen-syms-2.6.18-219.el5<br>
/boot/xen.gz-2.6.18-219.el5 <= 64-bit<br>
...<br>
<br>
# rpm -qpl kernel-xen-2.6.18-219.el5.i686.rpm<br>
/boot/.vmlinuz-2.6.18-219.el5xen.hmac<br>
/boot/System.map-2.6.18-219.el5xen<br>
/boot/config-2.6.18-219.el5xen<br>
/boot/symvers-2.6.18-219.el5xen.gz<br>
/boot/vmlinuz-2.6.18-219.el5xen<br>
/boot/xen-syms-2.6.18-219.el5<br>
/boot/xen.gz-2.6.18-219.el5 <= 32-bit<br>
...<br>
<br>
So, it's highly unlikely that either internally to Red Hat,<br>
or any of our customers, would ever run such a combination.<br>
And I don't recall ever working with the crash utility to<br>
support it.<br>
<br>
I'm curious whether anybody on this list has ever done this?<br>
<br>
After all these years of Xen existence, you would think that<br>
somebody else would have bumped into this anomoly before...<br>
