Hi Dave,

"crash xen-syms vmcore" works fine. Thank you !

BTW,
I think xendumps of fully-virtualized x86/x86_64 (also ia64) kernel
have a magic number XC_CORE_MAGIC_HVM(0xF00FEBEE) which is defferent
from para-virtualized. Please check.

I tried a xendump of fully-virtualized ia64 kernel
with change magic number check as follows.
---
xendump.h
+#define XC_CORE_MAGIC_HVM  0xF00FEBEE

xendump.c
-        if (xcp->xch_magic != XC_CORE_MAGIC)
+        if (xcp->xch_magic != XC_CORE_MAGIC && xcp->xch_magic != XC_CORE_MAGIC_HVM)
---
It works well execpt bt problem same as para-virtualized one.

Thanks.

Ah, OK -- we (Red Hat) are still using an older version of the
xenctrl library from (3.0.3), and it uses the old XC_CORE_MAGIC.

So I didn't see any difference between para- and fully-virtualized
magic numbers; I would guess that the difference is a change in
the library as opposed to para- vs fully-virtualized xendumps?

Here's my fully-virtualized x86_64 dump header:

My FV x86 from an x86 host:

and my FV x86 from an x86_64 host:

Anyway, I'm happy that everything still works with the new
magic number -- and whatever else might have changed with it.

Also, I appreciate your verification that crash works with
ia64 fully-virtualized xendumps (with your magic number fix).

I'll update the crash package to support the new magic value.

Thanks again,
