hello all,
i just finished installing openvz on opensuse 10.2
i used the following kernel:
http://download.openvz.org/kernel/branches/sles10-2.6.16/027 stab028.3/kernel-ovzpae-2.6.16.60_027stab028.3-0.23.i686.rpm

after installation, i tried creating using a precreated Suse template which is the following :

http://download.openvz.org/template/precreated/opensuse-10-i 386-default.tar.gz

and i got the following error:

openvz:~ # vzctl start 333
Warning: configuration file for distribution opensuse-10-i386-defaul not found default used
Starting VE ...
VE is mounted
Invalid kernel, or some kernel modules are not loaded
VE start failed
VE is unmounted

any help about this issue?!
i googled with no luck..!

any advice would be appreciated:)

Can you retry with the latest sles10 kernel?
http://wiki.openvz.org/Download/kernel/sles10

Also, what is your vzctl version? Maybe you need to upgrade to latest vzctl as well.

Indeed this is the latest kernel. Sorry I overlooked it.

I have filed a bug to bugzilla, we will investigate it. For now I recommend you to use RHEL5-based kernel.

Could you please check dmesg output and if there's an oops or some bad messages — please paste it here.

Also, lsmod output would be helpful, too.

What does /etc/init.d/vz status shows?

hey thanks for the help..! appreciate it..

anyway to answer your posts:

firstly, i tried using the kernel you suggested, it always ended up in missing dependencies which are initscripts and mkinitrd .. i didnt try to force it without dependencies though.

secondly, i just attached the output of lsmod ,and dmesg..

once again thanks for your help Smile

dmesg seems to be from a different kernel version (it says 2.6.18-something). We need the exact dmesg output from a kernel on which an error is happening, collected after the error has happened.

Alright, this last dmesg was from kernel 2.6.16-027test011-0.12-ovz.

Could you provide the one for the latest kernel, i.e. 027stab028.3, same conditions (after the error)?

sorry for the late reply.

i formated my box with suse 10.2 again.

installed the latest openvz kernel for suse, as well as a precreated template.

i could create/start the VE now normaly though with one prob!

theres no Yum, apt-get,wget in it!
its empty!
i tried downloading rpms through the node to the root file on the ve, and ther rpm -Uhv inside.. but theres a whole lot of dependencies!
i managed to get a few by installing a few packages, but theres a lot more!

is it normal to have a template without such crucial elements?!
or is it some bug! or..!

any advice on how to solve this issue would be appreciated:)
thanks for your help so far..

Roland, do you have an ipv6 module? It is not loaded - that's why the vzmon doesn't get in. Load one and everything will be OK.

so thats what actually solved it!

thank you for the valuable info, as i mentioned previously as i got frustrated, i ended up formating and going at it again with no prob, though i stayed curious to know wht happened.

you were right, as i formated my suse earlier, during the setup i disabled the ipv6 and i guess thats what cause all these probs, since the 2nd time i formated i left everything set by default and the prob didnt occur.

thanks for the info once again i appreciate it Smile
