[CVALE] kvm networking

[Patrick Bennett]

I know, it's a terrible choice of names, isn't it.  I think it stands 
for "kernel virtual machine" - a new kernel module that provides 
linux-kernel-native vmware-like capabilities.

It doesn't have to NAT, it can be a simple routed subnet also, however 
NAT is the default, I think.  Any way, if "bridging the guest's NIC to 
the host's NIC", for me, has not been all that simple.  However, I 
finally did revisit this page 
https://help.ubuntu.com/community/KVM/Networking and managed to get it 
working .... the info there is /almost/ right (for my setup anyway), and 
after a bit of struggle I did get it working!  Still no dhcp on the 
guest though - only static ip's are working - I'll cross this bridge 
later.  Perhaps when I have some time I'll write a little how to.

Thanks Ian for sending me back to the drawing board with a fresh 
outlook, sometimes that's exactly what I need.
