[PATCH] KVM-Test: Add KVM unit test (kvmctl)

[Lucas Meneghel Rodrigues]

From: sshang <sshang@redhat.com>

The test use kvm test harness kvmctl load binary test case file
to test various functions of the kvm kernel module.

This test is for older style unit testing, after some
consideration we decided to keep the 2 modules separated.

I thought that tool is deprecated (or even broken), and I was about to
suggest dropping it from the tree in favor of a simple script like this:

$QEMU -chardev stdio,id=cons -device testdev,chardev=cons -vga none \
	-vnc none -kernel $TESTCASE

The purpose of the this specific test module is to do the unit testing
in older branches of the code (such as RHEL 5.x branch). For upstream we
have another module that will use the -kernel option being worked. I
plan on calling it unit_test_kernel.

Ah, see. Thanks for the clarification.
