RE: [Xen-users] Xen 3.0.4 on RH EL 4.4 - can''t make it boot kerne l

I didn''t want to make the Xen kernel the default until I was
sure that it would boot correctly.

When I put the root=LABEL=/ on it I get an error:

mkrootdev: label / not found

Hi Tim,

The first thing I noticed in your grub.conf is that your xen configuration
have index value 0f 2, while the default=0. It should be default=2. I hope
this should sort the obvious problem.

Secondly, why are you not using root=LABEL=/ rather root=/dev/hda1! 

Cheers
Omer

I did some googling and found some indications that it might have been

and got the same results.

Any suggestions?

Yes, I''ve had problems using "LABEL=" on my system too - and
it''s really
not any difference - it''s just easier to change the root drive if you
use LABEL= on the kernel line. 

Can you post your /etc/fstab from the system you''re trying to boot?

Re: [Xen-users] Xen 3.0.4 on RH EL 4.4 - can''t make it boot kerne l

You would need to make it default, as a back you should add another
attribute to your grub.conf file:

default=2
fallback=0

So if default fails, then the fallback would be booted which is your normal
system ! With fallback option, you don''t end up into a dead lock where
you
can''t access your system! You are booting the xen kernal in the first
place,
and to do that the default option have to be set!

Cheers

RE: [Xen-users] Xen 3.0.4 on RH EL 4.4 - can''t make it boot kerne l

Why would it have to be the default? He can just pick it on the menu.

 

Those of us accustomed to ILOM server rooms don''t do that kind of

stuff usually, but maybe he''s at his desk.
