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.

virConnectClose calls virUnrefConnect which in turn closes all open drivers when the refcount of that connection dropped to zero. This works fine when you free all other objects that hold a ref to the connection before you close it, because in this case virUnrefConnect is the one that removes the last ref to the connection. But it doesn't work when you close the connection first before freeing the other objects. This is because the other virUnref* functions call virReleaseConnect when they detect that the connection's refcount dropped to zero. In this case another virUnref* function (different from virUnrefConnect) removes the last ref to the connection. This results in not closing the open drivers and leaking things that should have been cleaned up in the driver close functions. To fix this move the driver close calls to virReleaseConnect. |

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.
