passing disk geometry to installer
Hi,
I recently encountered a problem when trying to run the debian installer
within xen to install debian etch as a guest operating system.
When using a LVM volume mapped to let's say hda within the guest
operating system, the linux kernel was not able to guess the geometry of
the disk correctly probably because the emulated BIOS does not pass the
correct values.
Anyway, normally this would not be a problem since those parameters can
be passed to the kernel but with the current debian installer (I think
it was RC2 or RC3), I could not find a way to pass those parameters.
Specifying hda=C,H,S or hd=C,H,S on the boot promt did not help. The
later method was described in some rather old mailing list entry for
some very old debian installer.
So is there a way to pass this parameter to the installer, or is there a
way to modify the disk geometry after it has been detected by the kernel?
If there isn't, I think this is a feature that should be added since
more and more people are going to use their nice new CPUs to run virtual
hosts and they might run into the same problem.
Thanks
Ralph
