Re: [Xen-devel] newbie xen question

["B.G. Bruce" <bgb@xxxxxxxxx>]

It has been my experience (as short as it is with Xen) that having devfs
built into the kernel image that is booting a domU, irregardless of
whether or not you pass devfs=nomount or not, will result in this error
message.  Try compiling your domU kernel without devfs at all and see
what happens.
