What is the benefit of this ? I was hoping at some point to rip out all of those XEN_DOM0 and just have, mostly, CONFIG_XEN_BACKEND_SUPPORT (which would compile whatever is needed for HVM or PV guests to run blkback/netback/grant/grantalloc/etc) CONFIG_XEN_FRONTEND_SUPPORT (the vice-versa) CONFIG_XEN_PCI which would have the PCI support, the ACPI routing (which is predomaintaly most of the dom0 support), VGA text support, and whatever else is in there. In that fashion you could compile a kernel with CONFIG_XEN_BACKEND_SUPPORT without any CONFIG_XEN_PCI and drop it in as an HVM device driver domain. Thought maybe that wouldn't really work as if you do PCI passthrough to such domain, you are going to need the PCI support and ACPI routing. The VGA text maybe not... OK, never mind - we should brainstorm it and figure out how to make this nicely work. In the meantime this is OK.
