→Vmlinux, initrd and isolinux.cfg: this section is added
=== Vmlinux, initrd and isolinux.cfg ===
The next step is to force <tt>isolinux</tt> (cdrom boot loader) to boot OpenVZ kernel.
First, copy kernel image to OpenVZ CD:
<pre>
# cp root/boot/vmlinuz-2.6.18-ovz028stab035.1-smp ovz-livecd/boot/
</pre>
Modify initrd image. More precisely, we just need to add OpenVZ kernel modules there:
<pre>
# mkdir initrd.d
# cp ovz-livecd/boot/initrd.gz initrd.d/
# cd initrd.d/
# mkdir mount
# gunzip initrd.gz
# mount -o loop initrd mount/
# cp -r ../root/lib/modules/2.6.18-ovz028stab035.1-smp/ mount/lib/modules/
# rm -rf mount/lib/modules/2.6.18-ovz028stab035.1-smp/build # we don't neet it on initrd image
# sync
# umount mount/
# gzip initrd
# /bin/cp initrd.gz ../ovz-livecd/boot/initrd.gz
# cd ..
</pre>
Now we should modify <tt>ovz-livecd/isolinux.cfg</tt> file, that controls <tt>isolinux</tt> boot loader.
We inform boot loader, that new kernel was added by introducing the following changes (in diff format):
