Never did it, but your idea is very clear.
Could you provide any link ( manual ) how to build linux kernel with static command line ? Might be somewhere in menuconfig ?

Thanks any way.
Boris.
P.S. I've already made sure that Karmic Server works fine with legacy
grub installed.

Afaik grub2 does not pass the boot parameters "root=/dev/sda2 ro console=tty0" to the kernel in multiboot/module combination. I have seen the same problem on gentoo/grub2 and also read about this before. (This is not really Xen specific, but multiboot related)..
My workaround was to compile the kernel options as static cmdline into the kernel itself...

Best regards,
