OK kids, it’s Techie Time again. This is where I post something that I found out for myself, since using Google and searching forums got me nowhere. The hope is that search crawlers pick this up and help someone else out.

I was running into a problem using VMWare Server version 1.0.1 on a RHEL 4 system. On that system I had RHEL 4 virtual machine that we kept the kernel updated to the bleeding edge (but not the one RedHat officially releases). When I did the update to version 2.6.22.6, the virtual machine would not boot. An excerpt from the error messages on boot:

mkrootdev label / not found

Apparently there’s something wonky going on with the emulated hardware in the slightly older version of VMWare Server, causing the new kernel not to see the virtual disk. Updating VMWare Server to 1.0.4 fixed the issue (no need to rebuild the new kernel on the VM).

Hope that helps!

We now return you to your regularly scheduled program of nothing…
