The multiboot hint was very usefull, thanks...
But strange undeterministic things happen now... :(

snippet from my grub.cfg:

menuentry "xen" {
        multiboot /boot/xen-3.0.gz dom0_mem=512M
        module /boot/vmlinuz-2.6.22-14-xen root=/dev/mapper/mainVG-rootLV ro
        module /boot/initrd.img-2.6.22-14-xen
}


when I try to boot this directly, it says:
    "error: you need to load multiboot kernel first"

When I type manually (go to the grub command line after bios boot)
    multiboot /boot/xen-3.0.gz dom0_mem=512M
       it loads the xen and complains about not having any xenlinux 
kernel specified

When I type:
    multiboot /boot/xen-3.0.gz dom0_mem=512M
    module /boot/vmlinuz-2.6.22-14-xen
       It starts booting, but complains about the root device (which is 
obvious)

But when I type:
    multiboot /boot/xen-3.0.gz dom0_mem=512M
    module /boot/vmlinuz-2.6.22-14-xen root=/dev/mapper/mainVG-rootLV ro
       It starts booting but sometimes the error message is same as 
previous one (like there is no root option), sometimes there is wierd 
characters in root=....
       It looks like grub is not passing the arguments after file in 
module command correctly to the kernel. (But take it just as my guess)


Has anybody some hints what to do/try next?
