booting xen from coreboot

[Mikhail Savchenko]

Trying to boot xen from coreboot, using filo as payloader and mbootpack for
getting bzImage with xen and xenolinux, but always getting error, that my
loader not multiboot.

Also, trying to use grub as payloader, but cann't understand how setup it
right. Can anybody assist with solution of booting xen with coreboot?

Yeah, you can't do that - filo does not support multiboot for the kernel it's
trying to start.

You can make a kernel that has kexec support built in, boot that from filo,
and then make that kexec into the Xen kernel.

Or; you can use linux-as-a-bootloader to have that kexec kernel in the rom
chip, and kexec the xen kernel on the disk. Buildrom can help you to do that,
but it assumes at least a 1MB rom chip.

Sure, see above. We have machines running Xen using both methods described
above.
