Re: [Xen-users] supported distributions

[Arijit Ganguly <aganguly@xxxxxxxxx>]

I guess the reason why it is failing is the lack of driver support for dual drive bus existing  on dell pe1800. 

Besides, I have also been trying to recompile the kernel but end up getting an error in some driver.c file. 

I did the following:
Inside: xen-2.0
make world
cd linux-2.6.10-xen0
make ARCH=xen menuconfig
//selected my drivers and modules
make
I get error in balloon.c, in function balloon_process
line 210: phys_to_machine_mapping undeclared
line 210: INVALID_P2M_ENTRY undeclared. 

any clues

You probably need an initrd (even if the block device driver is compiled
in).

mkinitrd /boot/initrd-2.6.10-xen0.img 2.6.10-xen0

and add the corresponding line to grub

module initrd-2.6.10-xen0.img
