Hello All, I have a Linux (redhat) DomU(HVM) running on Xen-3.3.1 (on a CentOS Dom0). In the config file for this DomU, I have configured *on_crash="coredump-restart"* and started the DomU. Inside the DomU I do a *echo ''c'' > /proc/sysrq-trigger* and the DomU crashes with a kernel panic. But there is no coredump generated nor is the DomU restarted! I have modified in /etc/xen/xend-config.sxp enable-dump to yes and restarted xend. Since DomU is getting started properly shows that Xend has recognized the option on_crash=coredump-restart, but it does not dump core when the DomU crashes. So is there something I am missing or is this broken ? I did some digging in xen-users listings and found the below bug that says Fully Virtualized guests cannot communicate a panic to Xen and hence there is no core generated by Xen for the crashed DomU. https://bugzilla.redhat.com/show_bug.cgi?id=216498 So I tried the same "on_crash=coredump-restart" with a PVM(Linux redhat). And here also xen was not able to generate a core dump when the PVM kernel panicked. I also wrote a small module which calls BUG() and panicks the kernel but same results, Xen is not able to determine that DomU has crashed. Any thoughts, ideas? So if anyone knows what I am missing here please point me in the right direction. Any help is greatly thanked :) Best of Regards, Aravind _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
