So far I've only tested them in my test box, so I expect more issues will show up as this gets further testing. In any case, this is the bare minimum to get a PVH Dom0 working. In order to test them Xen 4.11 RC or plain master/staging should be used. Compile a Linux kernel with this patches and PVH support and add dom0=pvh to the Xen command line. The following message will be displayed during boot by the Linux kernel if PVH mode is used: "Booting paravirtualized kernel on Xen PVH" Thanks, Roger.
