Does the status XML have the 'query-hotpluggable-cpus' capability set? If it's so then it was probably mis-detected at start of the VM and should be fixed there. If there is no such capability, then the reconnect code is broken somehow. At any rate we should not re-detect the capabilities if they were reloaded properly from the XML. Peter
