Hi , my openvz server kernel have problem

i removed that with rpm -e . so now when i install kernel get this error mesage :


[root@serverd608 dl]# rpm -ihv ovzkernel-PAE-2.6.18-92.1.13.el5.028stab059.3.i686.rpm
Preparing... ########################################### [100%]
1:ovzkernel-PAE ########################################### [100%]
grubby fatal error: unable to find a suitable template
[root@serverd608 dl]#
[root@serverd608 dl]#
[root@serverd608 dl]# rpm -qa | grep kernel
kernel-2.6.18-53.el5
kernel-headers-2.6.18-92.1.17.el5
ovzkernel-PAE-2.6.18-92.1.13.el5.028stab059.3



so openvz boot menu config lines not added in grub.conf :


# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,0)
# kernel /vmlinuz-version ro root=/dev/sda2
# initrd /initrd-version.img
#boot=/dev/sda
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title CentOS (2.6.18-53.el5)
root (hd0,0)
kernel /vmlinuz-2.6.18-53.el5 ro
initrd /initrd-2.6.18-53.el5.img

where is the problem ?

thanks

Could you try installing some CentOS kernel and see if you get the same error?

I doubt the problem is ovzkernel-specific/related. So

1. check if grub and mkinitrd are installed correctly:

rpm -V grub
rpm -V mkinitrd

2. check if you get the same error from stock centos kernels, i.e. try to run rpm -ihv on some centos kernel (e.g. from centos updates).

Have you tried it *after* you saw the fail with ovzkernel?

Can I see how your /etc/boot/grub.conf looks like now?

See, this is why I asked you about it in the first place. The problem is not OpenVZ-specific.

I do want to help but I don't know the details of how grubby works. I recommend you to ask on some CentOS forum (and maybe post the solution here).

Weird. Please provide the output of

rpm -q vzctl
rpm -V vzctl
cat /etc/*release

sh -x /etc/init.d/vz restart (this one will be long)

Thanks. It looks like you were editing /etc/vz/vz.conf with some Windoze text editor. Don't do that since it inserts extra characters ("\r").

For now, try this to fix the file:

cat /etc/vz/vz.conf | tr -d '\r' > vz.conf.new && mv vz.conf.new /etc/vz/vz.conf


Then rerun /etc/init.d/vz restart and see if the above fix helped. If not, attach your /etc/vz/vz.conf here.

You're all set. The error you get ("/etc/init.d/vz: line 200: echo: write error: Broken pipe") is actually not an error but some harmless warning, which is fixed by the following patch:

http://git.openvz.org/?p=vzctl;a=commitdiff;h=79f91681e87b352a7511f52283105295c6e3a258

You can either safely ignore it or apply the patch.
