There will soon be two separate users of tc on virtual networks, and both will use the "qdisc root handle 1: htb" to add tx filters. One or the other could get the first chance to add the qdisc, and then if at a later time the other decides to use it, we need to prevent the 2nd user from attempting to re-add the qdisc (because that just generates an error). We do this by running "tc qdisc show dev $bridge handle 1:" then checking if the output of that command contains both "qdisc" and " 1: ".[*] If it does then the qdisc has already been added. If not then we need to add it now. [*]As of this writing, the output more exactly starts with "qdisc htb 1: root", but our comparison is made purposefully generous to increase the chances that it will continue to work properly if tc modifies the format of its output.

Libvirt API for virtualization
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.
For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.
