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.

If /tmp is mounted with the noexec flag (common on security-conscious
systems), then nwfilter will fail to initialize, because we cannot
run any temporary script via virRun("/tmp/script"); but we _can_
use "/bin/sh /tmp/script". For that matter, using /tmp risks collisions
with other unrelated programs; we already have /var/run/libvirt as a
dedicated temporary directory for use by libvirt.
* src/nwfilter/nwfilter_ebiptables_driver.c
(ebiptablesWriteToTempFile): Use internal directory, not /tmp;
drop attempts to make script executable; and detect close error.
(ebiptablesExecCLI): Switch to virCommand, and invoke the shell to
read the script, rather than requiring an executable script.

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.
