1. Does anybody know, where I can obtain the kernel-debuginfo and

I'm sorry, build of debuginfo packages is currently broken in spec.
however you can rebuild kernel with default config with enabled
debuginfo option
Thanks for your reply.
1. First I've realized that the newest version of ovz kernel has appeared.
And also there is an ovzkernel-debug package present.
Could you tell me, what the package ovzkernel-debug means ?
Will it enough for debugging the kernel coredump with crash utility ?
2. Following your advice,
I've rebuilded the kernel with the next way:
yum install auto-buildrequires gcc redhat-rpm-config
wget current_kernel_src.rpm
rpm -ivh current_kernel_src.rpm
cd /usr/src/redhat/SPECS/
set in kernel-ovz.spec:
%define _without_debuginfo 0
rpmbuild -bp kernel-ovz.spec
rpmbuild -ba --target=`uname -i` kernel-ovz.spec
And currently I have a choose what kernel version I need to install:
# ls -1 ../RPMS/x86_64/
ovzkernel-2.6.18-238.5.1.el5.028stab085.3.x86_64.rpm
ovzkernel-debug-2.6.18-238.5.1.el5.028stab085.3.x86_64.rpm
ovzkernel-devel-2.6.18-238.5.1.el5.028stab085.3.x86_64.rpm
ovzkernel-xen-2.6.18-238.5.1.el5.028stab085.3.x86_64.rpm
ovzkernel-xen-devel-2.6.18-238.5.1.el5.028stab085.3.x86_64.rpm
And I'm a little confused:
use the official openvz builded ovzkernel-debug \ ovzkernel
or install my own builded kernel ovzkernel or ovzkernel-debug ...
3. It's good for current versions of the kernel, however
how I can analize the obtained vmcores from previous kernels?
To analyze the vmcore with "crash" I need a corresponding mapfile for
that kernel versions.
Or there is not a big sense to do this?
2.
After upgrading the server for 16G ram, I started to see a lot of
kernel panics.
Please catch kernel panic messages and report to bugzilla.openvz.org
It says something like this:
RIP [<ffffffff802451ae>] rt_check_expire +0xea/0x23b
Kernel panic - not syncing: Fatal exeption
I'm not sure that this will be helpful without analyzing of kernel dump.
Thanks a lot!
