libvirt is a library, but libvirtd will manage kvm's for you
you just make xml (ew but oh well) configs for the vm, and use virsh to
fire them up
in terms of configuring network interfaces, you just set up a bridge
interface (brXX) and bond it to eth0, then in the vm configurations you
just specify the brXX interface. optionally you can set up network
"profiles" and abstract that details and reference it
libvirt.org covers it all
you dont need newer hardware, but with kvm its always best to get the
latest kernels and libvirt

If you're using libvirt to manage KVM (as Dean asked), then you _really_
want to be running something newer than that on the host. I'd recommend
(at least) Lucid. Also, depending on what you're doing, you may want to
run libvirt from a PPA (Lucid's will work, but upstream has fixed all
kinds of shit that hasn't made it into Ubuntu yet; libvirt is moving
fast [which is good]).
I will be setting up a new Lucid host, but currently experimenting on
Karmic. Should I buy the new host hardware first for the experimenting?
I've been looking at libvirt, but that's a library, not a configuration.
It doesn't tell me what I'm doing wrong. I'm getting messages like this:
warning: could not configure /dev/net/tun: no virtual network emulation
qemu: Could not initialize device 'tap'
I'm whistling in the dark right now. None of the man pages are clear to
me, and the google references are mostly old or confusing. I've been
using VirtualBox for quite a while but for my own reasons (read: Oracle)
I want to move away from it. In any case, VirtualBox is GUI based.
thanks
David.
