description: 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).

description: 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.

description: 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.
