Surprising (to me). Do you know what modifications in kernel-xen would be useful in a DomU? After your post, Googled the following which didn't turn up much useful for DomU (returned some hits for Dom0 likely because there were nothing more for DomU). There may be issues with certain kernels, but I haven't found a technical article yet that would suggest that kernel-xen should be a choice for DomU (although it may also be that there may not be much harm). If there is no advantage, I wonder if it should be recommended. xen "which kernel" DomU BTW - Searching the hits, although the following article discusses the Spice protocol it also contained a more general "Known Problem" requiring pci=nompci problem when booting kernel-xen in a DomU http://wiki.xen.org/wiki/SPICE_support_in_Xen Tony On Thu, Mar 12, 2015 at 7:09 PM, Jim Fehlig <jfehlig@suse.com> wrote:

I assume you are talking about this answer:
"The xen kernel is installed <only> in the HostOS (if needed). You do <not> install the xen kernel into a Guest (unless you're trying to deploy multiple layers of virtualization which is highly inadvisable). A "normal" kernel you'd normally install in a non-virtual environment should be used in your Guest, ie desktop, default, vanilla, etc."
But that is not true. kernel-xen is most certainly used in a PV guest. And in my case, the latest 13.2 kernel-xen works fine, but the latest from the Kernel:stable project does not.
