Change subject: core: prevent NPE when vm disappears from the host ...................................................................... core: prevent NPE when vm disappears from the host It is possible that from the monitoring point-of-view a VM disappears from the host. For instance, when powering-off a VM it suddenly stops being reported by the host (power-off calls 'destroy' so the VM is dropped from the list of running VMs on the host). In that case, the code that prepares the VMs for devices monitoring may lead to NPE. This patch prevents it by adding a null-check (obviously, the devices of such VMs should not be monitored at that point).
