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.

This should resolve https://bugzilla.redhat.com/show_bug.cgi?id=958907 Recent new addition of code to read/write active network state to the NETWORK_STATE_DIR in the network driver broke startup for qemu:///session. The network driver had several state file paths hardcoded to /var, which could never possibly work in session mode. This patch modifies *all* state files to use a variable string that is set differently according to whether or not we're running privileged. (It turns out that logDir was never used, so it's been completely eliminated.) There are very definitely other problems preventing dnsmasq and radvd from running in non-privileged mode, but it's more consistent to have the directories used by them be determined in the same fashion. NB: I've noted before that the network driver is storing its state (including dnsmasq and radvd state) in /var/lib, while qemu stores its state in /var/run. It would probably have been better if the two matched, but it's been this way for a long time, and changing it would break running installations during an upgrade, so it's best to just leave it as it is. |

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.
