Changes since v3:
- Remove pvh option from xl/libxl.
- Do not introduce a new domain type for libxl.
Changes since v2:
- Remove dom0pvh option from the command line docs.
- Bump domctl interface version due to the removed CDF flag.
- Introduce LIBXL_DOMAIN_TYPE_PVH.
- Remove "none" from the valid device model version options.
- Update the xl.cfg(5) man page to reflect the changes.

-PVH : an x86 PV guest running in an HVM container.
-
-See: http://blog.xen.org/index.php/2012/10/23/the-paravirtualization-spectrum-part-1-the-ends-of-the-spectrum/
-
-At the moment HAP is required for PVH.
-
-At present the only PVH guest is an x86 64bit PV linux. Patches are at:
- git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git
-
-A PVH guest kernel must support following features, as defined for linux
-in arch/x86/xen/xen-head.S:
-
- #define FEATURES_PVH "|writable_descriptor_tables" \
- "|auto_translated_physmap" \
- "|supervisor_mode_kernel" \
- "|hvm_callback_vector"
-
-In a nutshell:
-* the guest uses auto translate:
- - p2m is managed by xen
- - pagetables are owned by the guest
- - mmu_update hypercall not available
-* it uses event callback and not vlapic emulation,
-* IDT is native, so set_trap_table hcall is also N/A for a PVH guest.
-
-For a full list of hcalls supported for PVH, see pvh_hypercall64_table
-in arch/x86/hvm/hvm.c in xen. From the ABI prespective, it's mostly a
-PV guest with auto translate, although it does use hvm_op for setting
-callback vector, and has a special version of arch_set_guest_info for bringing
-up secondary cpus.
-
-The initial phase targets the booting of a 64bit UP/SMP linux guest in PVH
-mode. This is done by adding: pvh=1 in the config file. xl, and not xm, is
-supported. Phase I patches are broken into three parts:
- - xen changes for booting of 64bit PVH guest
- - tools changes for creating a PVH guest
- - boot of 64bit dom0 in PVH mode.
-
-To boot 64bit dom0 in PVH mode, add dom0pvh to grub xen command line.
-
-Following fixme's exist in the code:
- - arch/x86/time.c: support more tsc modes.
-
-Following remain to be done for PVH:
- - Get rid of PVH mode, make it just HVM with some flags set
- - implement arch_get_info_guest() for pvh.
- - Investigate what else needs to be done for VMI support.
- - AMD port.
- - 32bit PVH guest support in both linux and xen. Xen changes are tagged
- "32bitfixme".
- - Add support for monitoring guest behavior. See hvm_memory_event* functions
- in hvm.c
- - vcpu hotplug support
- - Live migration of PVH guests.
- - Avail PVH dom0 of posted interrupts. (This will be a big win).
-
-
-Note, any emails to me must be cc'd to xen devel mailing list. OTOH, please
-cc me on PVH emails to the xen devel mailing list.
