Add driver, which can report node info only.
Since this is the first commit in the series, can you please add more
information about pvs? This content from your 0/9 message would be
useful here:
Parallels Virtuozzo Server is a cloud-ready virtualization
solution that allows users to simultaneously run multiple virtual
machines and containers on the same physical server.
Current name of this product is Parallels Server Bare Metal and
more information about it can be found here -
http://www.parallels.com/products/server/baremetal/sp/.
This driver will work with PVS version 6.0 , beta version
scheduled at 2012 Q2.
I'm still thinking this series might be worth including in 0.9.12, but
I'm worried about getting good reviews (as you can see, I'm only on 1/9
and ran out of time today).
Thanks for your review, Eric !
Should I correct the issues right now and resend patches, or
it's better to wait for other patches review ?
changes:
* add me to AUTHORS
* fix indent in preprocessor directives in pvs_driver.h
* remove unneded include
* remove pvs_driver.c from po/POTFILES.in
Normally, it helps to list patch version history...

This will not work when cross-compiling. For that matter, 'uname -i' is
not portable. I'm not sure what better solution there is for deciding
whether to default things to true or false based on whether the $host
will be 64-bit, but it's certainly not right to be probing uname of $build.
There is a variable $|build_cpu|, we can check it instead of
running uname command.

Not a problem with your patch, per se, but we really should be using the
FSF-preferred form of LGPLv2+ boilerplate that uses a URL rather than a
street address (that's a global cleanup to all of libvirt).

Should we be checking for whether the PRLCTL binary even exists, before
registering this driver?
I check for prlctl binary existence in pvsOpen function, but
can move the check to pvsRegister.

Unusual ordering; typically, it's nice to keep case statements in the
same order as the enum declarations.
