Second hunk is to kill a compiler warning about mis-use of printf-style
format strings which kills the build on -Werror.

that finds the domid and console number corresponding to the primary
console of a given vm. The domid might be different from the domid of
the VM and the console number might not be 0 when using stubdoms.
The caller (xl_cmdimpl.c in this case) has to make sure that the stubdom
is already created before calling libxl_primary_console_exec in the hvm
case. In the PV case libxl_primary_console_exec has to be called before
libxl_run_bootloader.

LOG_WARNING (or precisely LOG_DEBUG if -v) would be logged.
xenconsoled only actually logs using LOG_ERR and LOG_DEBUG so for the
most part we would have been logging absolutely nothing up until now.
Linux provides a LOG_UPTO macro but I'm not sure how portable that is
so I have opencoded the list of levels.
Do I get some sort of prize for fixing a bug introduced in 2005?

When create DomU, if bootloader is specified, 'kernel/ramdisk' will be
used by bootloader when boots DomU. So it is needless to check the

Newer version of gdb, version 7*, seems to have bug where it is not
parsing thread list from gdbsx properly. Getting rid of the space in
thread list works around it. It's ok with older gdb also.

Useful if you need to read a guest filesystem (e.g. pygrub).
I'm not overly thrilled with the implementation WRT tap interfaces,
particularly WRT to detach. I was unable to find a way to get at the
paramters necessary to call tap_ctl_destroy so I assumed for now it
that is OK to assume that the tap device is going to be wanted for the
actual domain at some point in the immediate future and hence there is
no pressing need to destroy it.

This will allow us to map and then unlink the file and therefore
delete the process on process exit or explicit unmap.
Using the mmaped versions of these files required rewriting build_pv
to use the xc_dom builder functionality directly rather than through
the xc_linux_build "compatibility layer". (The status of the
xc_linux_build interface as a compatibility layer seems a bit dubious
since all existing callers use it but if anything is going to replace
it then libxl seems like the likely candidate).
I'm not thrilled with the definition of the maps lifecycle. This could
be solved by adding a helper function to explicitly free the toplevel
structure.

Use this to run xenconsole as the foreground process and move the
connection to the console in the "create -c" case early enough to be
able to view output from the bootloader. This behaviour is consistent
with how both "xm console" and "xm create -c" operate.

libxl would rather like to parse the output of pygrub. Rather than
implement an SXP parser in libxl add a --output-format option to
pygrub which can select an alternative, simpler to parse,
format. Available formats are:
sxp: current SXP output format;
simple: simple key+value output with \n separating item ( for
debugging). key and value are separated by a single
space (and key therefore cannot contain a space);
simple0: as simple but with \0 as a separator;
Also add --output-directory to allow temporary files to be placed
somewhere other than /var/run/xend/boot.

According to Intel 64 and IA32 Architectures SDM 3B Appendix B, Intel
Nehalem/Westmere processors provide h/w MSR to report the core/package
cstate residencies.Extend sysctl_get_pmstat interface to pass the
