VirtualBox in Knoppix 7.0.5 can't run rhel_6.0 x86_64 iso

[Capricorny]

Here are the two entries in legacy grub's menu.lst I use for the versien I am currently running:

title Knoppix 7.0.5r2 64 bits DVD cloop version  sda2 
      kernel (hd0,2)/boot/knx705/linux64 fromhd=/dev/sda2 knoppix_dir=KNOPPIX705_clr2 nosound keyboard=no ramdisk_size=100000 lang=no apm=power-off initrd=minirt.gz nomce libata.force=noncq hpsa.hpsa_allow_any=1 loglevel=1 tz=localtime
      initrd (hd0,2)/boot/knx705/minirt.gz

title Knoppix 7.0.5r2 32 bits DVD cloop version  sda2 
      kernel (hd0,2)/boot/knx705/linux fromhd=/dev/sda2 knoppix_dir=KNOPPIX705_clr2 nosound keyboard=no ramdisk_size=100000 lang=no apm=power-off initrd=minirt.gz nomce libata.force=noncq hpsa.hpsa_allow_any=1 loglevel=1 tz=localtime
      initrd (hd0,2)/boot/knx705/minirt.gz

To get 64-bits kernel, I use the linux64 kernel.

The most important other options used here:

* Booting from a separate partition that is nomally not mounted (/dev/sda3 = (hd0,2) for legacy grub )
* Using a separate boot subdirectory (/media/sda3/boot/knx705) for the Knoppix 705 files
* Using the main Windows partition for Knoppix system (/dev/sda2)
* Using KNOPPIX705_clr2 as Knoppix-dir instead of KNOPPIX (Denotes cloop remastering #2 of 7.0.5)

For experimentation, entries for other Knoppix subdirectories, other kernels other minirt versions etc can be added.

How to work with other bootloaders - i don't exactly know.

Ah!... Now I got it, it's Linux64, not Knoppix64! Really, highly knowledgeable people don't tend to go back to what they have written! And mere mortals like us die of choking in the water bucket!

Yes, it can be really confusing - knoppix64 is the name of a standard option in the default CD/DVD/USB booting of Knoppix. Those options can be edited/added in "micro-remastering". Using grub, we refer to the actual booting files. (I think that applies for all grubs, but I only use legacy so far.) Good luck

The following link explains the reason why the emulation does not happen, thanks to able and patieint guidance by the Debian forum members pdespite my dumbheadedness. http://forums.debian.net/viewtopic.p...103157&start=1
