This is rudimentary support for parts of the BIOS Boot Specification,
just enough to use Etherboot ROM images.

On IA32 host or IA32 PAE host, at present, generally, we can't create
an HVM guest with more than 2G memory, because generally it's almost
impossible for Qemu to find a large enough and consecutive virtual
address space to map an HVM guest's whole physical address space.
The attached patch fixes this issue using dynamic mapping based on
little blocks of memory.

This is done by the populate_physmap hypercall.
2. Xen now translates foreign mappings from GMFN->MFN.
Tools are simplified because of this.

Allocate HVM guest memory in the libxc builder function rather
than in xend. Clean up fall out from these changes.
Todo: Fix ia64. Move PV builder to same model (it should allocate the
memory rather than xend doing so -- then it can avoid using
xc_get_pfn_list()).

that the VNC server from qemu listens on.
Defaults to only listen on 127.0.0.1
The old behaviour (listen on all interfaces) can be restored, by
- changing the system-wide default in /etc/xen/xend-config.sxp by adding:
(vnc-listen '0.0.0.0')
- changing individual domain config files by adding:
vnclisten="0.0.0.0"
Also allows specifying the hostname associated with an interface to limit
to that interface.

Changes are:
1) M2P table and e820 table are changed to skip address space from
HVM_RAM_LIMIT_BELOW_4G to 4G.
2) shared io page location, when less than HVM_RAM_LIMIT_BELOW_4G
memory, it's the last page of RAM as today, or it's the last page of
HVM_RAM_LIMIT_BELOW_4G RAM.
3) in qemu-dm address space from HVM_RAM_LIMIT_BELOW_4G to 4G are
stuffed with mfns starting from 4G, so the 1:1 mapping can still works.
This is ugly, but another limit check patch as changeset 10757 will
prevent qemu-dm to access this range. This ugly stuffing will be
removed when the patch to remove 1:1 mapping from qemu-dm gets accepted
in the future.

qemu-dm runs daemonized and the default for -nographic is to redirect
the monitor and serial ports to stdio which causes qemu-dm to busy
read from stdin. Change the default for -nographic to redirect the

device model. To support USB there are two new optional config lines
that can be added to the guest config file:
usb=1
This will enable USB without defining a specific USB device.
This option is assumed and not needed if the `usbdevice' option
is given.
usbdevice='device'
This will enable USB and also enable support for the given device.
Currently, the only two devices are `mouse' (a PS/2 mouse) and
`tablet' (an absolute pointing device). The advantage of `tablet'
is that Windows guests will automatically recognize and support this
device so specifying the config line:
usbdevice='tablet'
will create a mouse that works transparently with Windows guests
under VNC. (Linux doesn't recognize the USB tablet yet so Linux
guests under VNC will still need the Summagraphics emulation.)

qemu will emulate up to 4 serial lines (COM1 - COM4). One of these
lines supports a Summagraphics protocol. This has changed recently,
and it's now always COM2. This patch allows the user to specify
to qemu which lines should be serial lines, and the code will place
the Summagraphics compatible line at just above the last specified
serial line. qemu defaults serial line 0 (COM1) to be "vc", resulting
in the Summagraphics support residing on COM2. This is in keeping
with the current behavior.
The results, via qemu command line, are:
<none> COM2
-serial x COM2
-serial x -serial x COM3
-serial x -serial x -serial x COM4
-serial x -serial x -serial x -serial x <none>
The results are deterministic, and allow the use of up to 4 serial
lines including none with Summagraphics support. There is no
change from current behavior, unless requested.

There are some usage scenarios in which differing user domains want
to be using different base TOD clocks. This patch adds the ability
to specify the base TOD time difference. The patch also adds a
hook point to notify another entity when the domain changes this
offset. This might occur, for instance, on a Linux domain using
hwclock -w.

initial vga mode and linear framebuffer.
When creating device model, the vga memory is allocated through
xc_domain_memory_increase_reservation(), however, when switch to use
linear framebuffer, we didn't free that memory, and re-allocate the vga
memory through set_mm_mapping(), that caused memory leak. Now it is
changed to just using qemu_malloc when create device model, and free
that memory when switch to linear framebuffer.
After unset_vram_mapping(), the old memory pointer should be
unmapped; after set_vram_mapping(), the old memory should be freed.

1) Move the tablet to the second serial port. This way the tablet will
not interfere with people who want to use a serial console on the guest.
2) Enhance the Summagraphics emulation so that the Windows XP driver
works. Turns out the Windows driver was using capabilities the X driver
didn't care about and it wouldn't recognize the tablet without these
capabilities.
