Most management stacks and cloud frameworks seem to be using libvirt
nowadays. And that's a good thing because a lot of work goes into
libvirt to use the latest and greatest QEMU options, set up networking
and firewalls, PCI passthrough, device hotplug, etc.
So start by looking at http://libvirt.org/ to see if it meets your
needs.
If you really want to write your own library, learn the QEMU
command-line and QMP monitor. See docs/qmp/qmp-spec.txt and
scripts/qmp/qmp-shell for QMP examples.
Also consider that writing your own library means you'll have to study
the man pages and QEMU source code. Here is a very quick overview of
QEMU to get you started:
