qemuAgentNotifyEvent accesses monitor structure and is called on qemu reset/shutdown/suspend events under domain lock. Other monitor functions on the other hand take monitor lock and don't hold domain lock. Thus it is possible to have risky simultaneous access to the structure from 2 threads. Let's take monitor lock here to make access exclusive.
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.
