Currently when libvirt has a serious error doing I/O and/or parsing
of the QEMU monitor, it will kill off the guest. Application developers
have expressed a desire for more graceful handling of this scenario.
In particular to allow the guest OS to continue to run, without any
further monitor interactons, and then kill/restart it at a time which
is convenient to the guest admin/apps.
This is a proof of concept of that.
