Attaching to a existing qemu process allows to get us into a situation when qemu is new enough to have JSON monitor and new vCPU hotplug but the json monitor is not used. The vCPU detection code would require it though. This broke attaching to qemu processes. Make the condition less strict and just skip the vCPU hotplug detection if JSON monitor is not available. Resolves one of the symptoms in: https://bugzilla.redhat.com/show_bug.cgi?id=1378401
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.
