Now, 'onehost show 6' results in the following (see below).<br><br>As you can see, although the monitoring info returned the correct result, it still contains an error message, which is stuck there from an earlier time (the timestamp of the error message is not the actual time of the monitoring, it shows the timestamp of an earlier unsuccessful monitoring try). The oned.log contains no errors. Also, I suppose because of this error message (which also
appears at the bottom of the "Host Template" tab, with my current Host selected in Sunstone), the "Monitoring Information" tab shows "There is no monitoring information for
host 6" both at CPU and Memory info. <span style="font-weight: bold;">Any idea how to work this around?</span><br><br>Also, my initial socket problem (I copy the following from messages.log):<br>Mar 9 10:10:57 pcls libvirtd[5603]: Starting libvirtd <span style="font-weight: bold;">WARNING: no socket to connect to</span><br>Mar 9 10:10:57 pcls libvirtd[5603]: ..done<br><br>, still persist.

of it so far. It is also making it hard to trace the fact that besides this warning message, no errors messages are issued nowhere, and I couldn't trace it in the logs neither, so far. <span style="font-weight: bold;">Any ideas what causes this socket warning?</span> Please help.<br><br>All the best,<br>Lehel.<br><br><br><br>> onehost show 6<br>HOST 6 INFORMATION <br>ID : 6
