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.

Prior to this patch, every test:/// URI has its own event manager, which means that registering for an event can only ever receive events from the connection where it issued the API that triggered the event. But the whole idea of events is to be able to learn about something where an API call did NOT trigger the action. In order to actually test asynchronous events, I wanted to be able to tie multiple test connections to the same state. Use of a file in a test URI is still per-connection state, but now parallel connections to test:///default (from the same binary, of course) now share common state and can affect one another. The updated testsuite fails without the rest of this patch. Valgrind didn't report any leaks. * src/test/test_driver.c (testConnectOpen): Move per-connection state initialization... (testOpenFromFile): ...here. (defaultConn, defaultConnections, defaultLock, testOnceInit): New shared state. (testOpenDefault): Only initialize on first connection. (testConnectClose): Don't clobber state if still shared. * tests/objecteventtest.c (testDomainStartStopEvent): Enhance to cover this. (timeout, mymain): Ensure test fails rather than blocks.

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.
