Hi all I used kernel-3.10.68-11.el6 as dom0 and config kdump I have got vmcore file when compute crash, but not found debuginfo package from http://debuginfo.centos.org/ I found kernel-3.10.68-11.el6 set CONFIG_DEBUG_INFO=n Why not set this key? Is there any other method to debug when compute crash Best Wishes Ding -------------- next part -------------- An HTML attachment was scrubbed...
