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.
