ioemu fixes: do not install into /usr/share/qemu as it conflicts with
real qemu installations. Also, do not link x86/64 with a special linker
script -- breaks on SLES9 and ought to be unnecessary.
The linker scripts and configuration/Makefile environment all need
stripping out at some point.

[PATCH] [PATCH] ioemu: enable Cirrus VGA emulation
At some point the Cirrus VGA driver was commented out. Probably
for debugging. The patch below adds it back in. It works just fine.

[PATCH] xen.vncserver-quiet-configure.patch

Nothing but vnet uses libxutil -- move it there.
Makefile, xc.c, setup.py, configure, configure.in, Makefile.in:
This doesn't use libxutil.
Makefile, Makefile.vnet, Rules.mk:
Move libxutil into vnet since it's only used there.

Remove docs and tests from qemu-ioemu: they mostly pertain to whole

[PATCH] [PATCH] Assorted VMX patches
This patch contains the following VMX patches:
- ioemu: Update the address when doing a stosb/stosw/stosl. Without this patch
stosb writes req->count times at the same location req->addr. Not exactly
the intended semantics.
- xc_ptrace.c: Use the page_array to refer to partition memory. This allows
you to use gdbserver on a VMX partition (and presumably partitions that use
shadow page tables).
- dom0_ops.c: Preserve ECF_VMX_GUEST flag for gdbserver. Without it you
cannot (re)set the VMX domain state.
- vmx.c: Added support for lmsw. Unmodified FreeBSD uses this when running
inside a VMX partition.

[PATCH] [PATCH] VMX support for MMIO/PIO in VM8086 mode
Memory mapped and port I/O is currently broken under VMX when the
partition is running in VM8086 mode. The reason is that the instruction
decoding support uses 32-bit opcode/address decodes rather 16-bit
decodes. This patch fixes that. In addition, the patch adds support for
the "stos" instruction decoding because this is a frequently used way
to clear MMIO areas such as the screen.
As an aside, vmx_platform.c should really reuse x86_emulate.c as much
as possible.

Subject: [PATCH] pit-in-hv.patch
- Use ac_timer for PIT interrupt injection (more accurate time keeping)
- Accelerate some critical PIT I/O operations in the hypervisor
(saves 15us per op). Cuts down guest timer interrupt handler execution time
by a third.
- If the domain is scheduled out, make sure that interrupts are not lost
- Add a generic framework for device I/O interception

- Detect the CPU speed automatically, rather than having the user
specify a ips in bochsrc. The user can still specify it to override
the auto-detected value.
- Care should be taken to make sure that tsc_per_bx_tick is not too
small or too big. Otherwise, numerical precision issues may result
in the wrong calculation of elapsed time

Right now, the memory for the 1:1 physical mode page tables comes from the
VMX domain's memory. With this change, when the user asks for a domain with
M Megabytes of memory, we actually allocate M+N megabytes in xend, where
N is the memory for the page table pages.
This simplifies the code in the device models that maps guest memory (we
now map all of it) and the E820 map can also give the full M megabytes to
the guest.
