Currently whenever there is any failure with parsing the monitor, this is treated in the same was as end-of-file (ie QEMU quit). The domain is terminated, if not already dead. With this change, failures in parsing the monitor stream do not result in the death of QEMU. The guest continues running unchanged, but all further use of the monitor will be disabled. The VMM_FAILURE event will be emitted, and the mgmt application can decide when to kill/restart the guest to re-gain control * src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h: Run a different callback for monitor EOF vs error conditions. * src/qemu/qemu_process.c: Emit VMM_FAILURE event when monitor fails
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.
