Hi, The following patchset is to support extracting vmcoreinfo from /proc/vmcore for Xen. This is the up-port of the patchset I made for 3.2.0 and posted the end of March. [PATCH 1/2] patch for xen hypervisor (xen-unstable.hg) [PATCH 2/2] patch for linux (linux-2.6.18-xen.hg) --- background ---------------------------------------------------- * what the makedumpfile is: To shorten the size of the dumpfile and the time of creating the dumpfile, makedumpfile copies only the necessary pages for analysis to the dumpfile from /proc/vmcore. You can specify the kind of unnecessary pages with dump_level. If you want to shorten the size further, enable the compression of the page data. * Xen extraction makedumpfile also has a feature that extracting the part of xen hypervisor and domain-0 from /proc/vmcore taken under xen environment. In most cases under xen environment, it is enough to analyze a cause of system crash. * extract vmcoreinfo from /proc/vmcore makedumpfile 1.2.0 supports to extract the vmcoreinfo data from /proc/vmcore and uses it for dump filtering. (for a vmcore taken under the native environment.) ------------------------------------------------------------------ Thanks. -- Itsuro ODA <oda at valinux.co.jp>
