What is wrong with this sl71 grub.cfg menuentry?

[ToddAndMargo]

Hi All,

I am trying to run SL7.1 as a VM from SL6.6 KVM using
SL-71-x86_64-2015-03-27-LiveDVDgnome.iso
The Nitrogen menuentry in grub.cfg causes a kernel
panic (the rescue modes do work after fixing a typo).

kernel panic:

     Failed to access perfctr msr (MSR c1 is 0)
     kernel panic -- not syncing:L VFS: Unable to mount root fs on 
unknown-block(0,0)

Anyone know what is wrong with this menuentry?

Many thanks,
-T
