Work toward making a "Linux KVM" /dev/kvm compatible device for Solaris.

To build the kvm kernel module, run make.
(Hopefully there are no hardcoded path names, but if so,
they are coming from solaris source.)
This will result in a file, kvm.

To install:
=================

#!/bin/sh
cp kvm /tmp
psradm -f 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15  # shouldn't need this...
ln -s /tmp/kvm /kernel/drv/amd64/kvm
cat > /kernel/drv/kvm.conf <<EOF
name="kvm" parent="pseudo";
EOF
add_drv kvm
ln -s /devices/pseudo/kvm@0:kvm /dev/kvm

=========================

I have been re-enabling a processor after it is installed (psradm -n 1).
To run user level qemu:

# pbind -b 0 $$
# qemu-system-x86_64 -enable-kvm -kernel kvm.vmlinuz -initrd kvm.initrd -nographic -boot d -m 512 -net nic,model=virtio,name=virtio.0 -net user -vnc 0.0.0.0:0 -no-acpi -no-hpet

Instead of -kernel and -initrd options, you can specify an iso image (I think at the end of the line).
Currently, there are just a few messages printed out (most of the debug output is
currently ifdef-ed out).  If you forget to do the pbind, count on getting a panic very quickly.

NOTE:  Currently, you can run qemu/kvm 1 time for a given boot session.  In other
words, 2 or more instances of qemu/kvm running at the same time is not supported, and neither
is exiting one instance and starting another without a reboot in between.  This should not
be too difficult to fix, but I think getting it to come up is more important right now.
