makedumpfile-1.1.5: Xen support
Subsystems (2)
Quoted 8 lines
Changelog:
o Add a new feature that extracting the part of xen hypervisor and domain-0 from/proc/vmcore. In most cases under xen environment, it is enough to analyze a cause of system crash.
The patch was provided by Itsuro Oda.
Usage:# makedumpfile -E --xen-syms xen-syms /proc/vmcore dumpfile
Can you verify that the dumpfile created above is usable as both a hypervisor dumpfile as well as a dom0 vmlinux dumpfile? In other words, can both of the following sessions be accomplished with the resultant dumpfile?
# crash xen-syms dumpfile
and:
# crash vmlinux dumpfile
Thanks,
Dave

Great -- thanks.
Is the "-d" dump_level option completely ignored, or can it (without vmlinux awareness) recognize and skip zero-filled pages?

Yes, "-d" is ignored.
Hmm, adding to skip zero-filled pages is easy but I wonder how effective it is ...
Thanks.

I found it is sometimes effective.
The attached patch enables the "-d" option with --xen-syms. Note that only the level 1 (skip zero-filled pages) is supported.
ex. # makedumpfile -E -d 1 --xen-syms xen-syms.debug vmcore output
Thanks.
