[gentoo-user] grub2-mkconfig vs. xen

[Konstantinos Agouros]

Hi,

I have a box running a xen-domu. If I want to use grub2-mkconfig,
I learned that I have to put the kernel-.config into /etc/kernels.
However this does not create an entry which includes the initrd
(it creates one without xen though).
How do I achieve this? Also I only want entries with xen and I need
to pass some params to xen as well as the linux kernel. Which entries
in /etc/default/grub do that?

Regards,

Konstantin

chmod -x /etc/grub.d/10_linux
to prevent the creation of standard linux stanzas.

The configuration section of info grub details the settings in defaults,
you want to look at GRUB_CMDLINE_XEN and GRUB_CMDLINE_XEN_DEFAULT.

You may put your kernel configuration in /boot as well. The important 
thing is to have xen enabled in that configuration - that is what grub 
looks for. It only creates xen entries if xen is enabled. Also the name 
must match - for example config-*, kernel-* and so on. You can can set 
to boot xen by default with grub2-set-default (specify the menuentry) - 
it's written to grubenv. Before that, set GRUB_DEFAULT="saved" to 
/etc/default/grub.
