Re: [Xen-devel] newer domU older hypervisor?

["Andrew D. Ball" <aball@xxxxxxxxxx>]

Unfortunately, I think you are likely to have issues here.  You may have
luck having things at least work for basic functionality, but you
definitely need to match the hypervisor and dom0 kernel w/ the tools.

IMHO, it's a snafu to upgrade para-virtualized domU kernels that needs
to be addressed better.

Peace.
