[Xen-devel] Re: Failure to setup Xen 3.4.1 Dom0 on top of Ubuntu 9.10 Server HVM DomU ( 2.6.30.2 xenified kernel)

[Christian Tramnitz <chris.ace@xxxxxxx>]

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,
   Christian
