If QEMU shuts down while we're in the middle of processing a monitor command, the monitor will be freed, and upon cleaning up we attempt to do qemuMonitorUnlock(priv->mon) when priv->mon is NULL. To address this we introduce proper reference counting into the qemuMonitorPtr object, and hold an extra reference whenever executing a command. * src/qemu/qemu_driver.c: Hold a reference on the monitor while executing commands, and only NULL-ify the priv->mon field when the last reference is released * src/qemu/qemu_monitor.h, src/qemu/qemu_monitor.c: Add reference counting to handle safe deletion of monitor objects
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.
