[KVM_AUTOTEST] unattended installs

[David Huff <dhuff@redhat.com>]

Ok, I am sending out the first pass at the unattended install scripts.  I have
tested with both Linux and Windows guests and everything seems ok.  I have been
hitting a couple issues and I am sure there are more that need to be resolved
however I wanted some initial feedback...

Requires the processor patch as well as the patch to "strip and split" to allow
extra =.

Windows guests will automatically pick up a .sif file on the "floppy disk" while
linux guest require pxe to pass in the kernel parameter "ks=floppy" to force an
unattended install.  This also allows for pxe to pass in additional kernel
parameters specified in the config file.

I had some issues getting the guest to read a vvfat floppy passed to the guest
via qemu option "-fda fat:floppy:rw:./floppy" it would pass the dir as a vfat
disk and the guest could mount it, however guest could not read the files on the
vdisk......
