Booting a Xen PVH guest requires a special boot entry as it is mandatory to setup some Xen-specific interfaces rather early. When grub or OVMF are used as boot loaders, however, those will fill the boot parameters in zeropage and there is no longer a need to do something PVH specific in the early boot path. This patch series adds support for that scenario by identifying PVH environment and doing

OK, so after several weeks of trying to get various versions of Xen running of various distributions, I''m starting to wonder if I''ve got a hardware compatibility problem and as the system never really boots with the Xen kernel I''ve got no log files to tell me where the problem is. I was wondering if there''s a way to compile from source with debug turned on,

Hi Ingo, Here''s the chunk of patches to add Xen Dom0 support (it''s probably worth creating a new xen/dom0 topic branch for it). A dom0 Xen domain is basically the same as a normal domU domain, but it has extra privileges to directly access hardware. There are two issues to deal with: - translating to and from the domain''s pseudo-physical addresses and real machine
