The 'vga=' boot option is extended as follows:
----------
'vga=<mode-specifier>[,keep]' where <mode-specifier> is one of:
'vga=ask':
display a vga menu of available modes
'vga=text-80x<rows>':
text mode, where <rows> is one of {25,28,30,34,43,50,60}
'vga=gfx-<width>x<height>x<depth>':
graphics mode, e.g., vga=gfx-1024x768x16
'vga=mode-<mode>:
specifies a mode as specified in 'vga=ask' menu
(NB. menu modes are displayed in hex, so mode numbers here must
be prefixed with '0x' (e.g., 'vga=mode-0x0318'))
The option 'keep' causes Xen to continue to print to the VGA console even
after domain 0 starts to boot. The default behaviour is to relinquish
control of the console to domain 0.

When I tested xm mem-max and xm list, I saw the following error
message by xm list. Because xm mem-max always changes
"memory_static_max", I think that the cause of the error message
is it. This patch fixes it.
# xm list --long PVdomain.1 | grep mem
(maxmem 1024)
(memory 1024)
(shadow_memory 0)
# xm mem-max PVdomain.1 512
Error: (22, 'Invalid argument')
Usage: xm mem-max <Domain> <Mem>
Set the maximum amount reservation for a domain.
# xm list --long PVdomain.1 | grep mem
Error: memory_dynamic_max must be less than or equal to
memory_static_max

Use atomic updates to read/write usb controller data.
This can be done because:
a) word copies on x86 are atomic
b) The USB spec requires word alignment
This will need to be enhanced once USB 1.2 is supported.

e.g., after domain crash or reboot) where previous log file is
immediately overwritten. Not using domain names in logs avoids and

If we located the Linux tree by deriving the path from "hg path
default" and it is a local path then prepend "file://" to prevent us
trying to symlink it.
Unfortunately mercurial doesn't understand file:// URLs so we have to
strip it off again before calling hg clone.

Syslinux can load 32-bit UI code for menu handling. But the core of
syslinux is still 16-bit. When it jumps to this 32-bit code, it
installs a set of 32-bit interrupt trap handlers which just bounce the
interrupts back to 16-bit mode.
But this plays badly with vmxassist. When running 16-bit boot loader
code, vmxassist installs its own trap handlers which bounce vPIC
interrupts back down to 16-bit mode. The trap handlers live at
int 0x20 to 0x2f, so when the 16-bit code tries to reprogram the vPIC,
vm86 rewrites the outb()s on the fly to set the irq_base vectors
accordingly.
So when syslinux enters 32-bit mode, the vPIC has still been
programmed to point to vmxassist's bounce traps, even though vmxassist
is no longer active once the guest is running 32-bit code. So the
wrong interrupts get delivered to the guest.
Fix this by restoring the rombios vPIC irq_base vectors when we leave
vmxassist mode, and returning the vmxassist traps when we reenter it.
These irq base values are hard-coded in this patch, but they are
already hard-coded in vmxassist so any boot code that relies on
changing them will already fail.

Change the logfile name generated by qemu-dm to use the pattern
qemu-dm-[NAME].log instead of qemu-dm-[PID].log. This makes it
easier for the adminsitrator to figure out which log corresponds to
which guest (particularly after a crash where you no long know what
PID the qemu-dm process for your guest had). It also prevents the
number of log files from growing unbounded.

* The --log command line argument takes one of 4 values
- none - no logging (the default)
- hv - log all hypervisor messages
- guest - log all guest messages
- both - log all guest & hypervisor messages
* The --log-dir command line argument takes a path to specify where
to store logfiles. If omitted it defaults to /var/log/xen/console
* The hypervisor logfile is $LOGDIR/hypervisor.log
* The guest logfile is $LOGDIR/guest-[NAME].log
* If receiving a SIGHUP it will close & re-open all log files to
enable logrotate to do its magic
* Fixes the permissions of /var/run/xenconsoled.pid
* Adds a --pid-file command line argument to override the default
location of pid file (this is not really related to logging, but
since I was in that code...)
