This is during boot up:
It has grabbed the kernel, and initrd if you specified one. Next thing it does is mount / ro - all before init is started.

It can't find /. Causes: Wrong drive specified, pathname error, unable to read filesystem, i/o error, that sort of thing

Double check that your kernel can read trhe root filesystem. It has to be compiled in, or in an initrd. A module isn't enough; it lands you in catch-22 - you need the module to read the filesystem the module is on.

Then you have the root drive specified wrong. root=/dev/??? on the boot line. Modern kernels should have /dev/sda, etc.

vl 6.0 uses kernel 2.6.27.12 and vl 7.0 kernel 2.6.38

Because it's a backdoor to ram.
