Instructions manually create a minimal openSUSE 10.3 template.
Contents
Prerequisites
You need running openSUSE 10.3 installation.
Creating template
Preparing the base system
Run yast2 on your openSUSE 10.3 installation (this does not have to be your OpenVZ HN, you can prepare cache on one box and put it on your OpenVZ HN). Proceed with Software->Installation into directory option. It is assumed that this directory is current directory in following instructions (unless otherwise stated).
Create device nodes
I suggest creating all required nodes directly in the lib/udev/devices/, in that case you don't have to disable udev in startup scripts.
Execute the following commands to create device files:
mknod -m 666 lib/udev/devices/full c 1 7 mknod -m 600 lib/udev/devices/initctl p mknod -m 666 lib/udev/devices/random c 1 8 mknod -m 444 lib/udev/devices/urandom c 1 9
Replace console device with regular file (otherwise vzctl stop fails with timeout -- needs more investigation):
rm lib/udev/devices/console ; touch lib/udev/devices/console
Disable parallel startup of services
Set RUN_PARALLEL variable in <DIRINSTALL>/etc/sysconfig/boot to "no".
Disable boot.klog
For some reason, klogd hangs when tries to retrieve kernel log. You need to disable it. Simply delete etc/rc.d/boot.d/S08boot.klog
Create OS template
Create OS template cache by invoking the following command:
tar -czf /vz/template/cache/opensuse-10.3-i386-default.tar.gz ./
|
Note: For Debian-based host you should put the archive inside /var/lib/vz/template/cache
