When a qemu domain is to be rebooted, from outside, at libvirt level it looks like regular shutdown. To really restart the domain, libvirt needs to issue reset command on the monitor once SHUTDOWN event appeared. So, in order to differentiate bare shutdown and reboot libvirt uses a variable within domain private data. It's called fakeReboot. When the reboot API is called, the variable is set, but when the shutdown API is called it must be cleared out. But it was not for every possible case. So if user called virDomainReboot(), and there was no ACPI daemon running inside the guest (so guest didn't initiated shutdown sequence) and then virDomainShutdown(mode=agent) was called bad thing happened. We remembered the fakeReboot and instead of shutting the domain down, we just rebooted it.

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.
