Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.

part, this doesn't really concern libvirt, since for things like attach and detach we just pass it through and let xend worry about whether it is supported or not. The one place this breaks down is in the stats collecting code, where we need to figure out the device number so we can go digging in /sys for the statistics. To remedy this, I've re-written xenLinuxDomainDeviceID() to use regular expressions to figure out the device number from the name. The major advantage is that now xenLinuxDomainDeviceID() looks fairly identical to tools/python/xen/util/blkif.py (in the Xen sources), so that adding additional devices in the future should be much easier. It also reduces the size of the code, and, in my opinion, the code complexity. With this patch in place, I was able to get block statistics both on older style devices (/dev/xvda) and on the new, expanded devices (/dev/xvdaa).

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
