I have been beating up myself for the last few hours and I was getting the same error that you posted. ****************Test Environment************** 2 Laptops 1 of the two laptop has several linux KVMs ********************************************** The reason why you are not able to connect with the KVM Guest is because by default KVM Guest uses VNC, which will conflict with tiger-vncserver. What is your current VM environment, to resolved the issue I switch from VNC to spice for the choice of display for the KVM Guest and I was finally able to establish communication with the KVM guest. Let me know if this works for you. > _______________________________________________ > CentOS mailing list > CentOS at centos.org > http://lists.centos.org/mailman/listinfo/centos -- Kind Regards Earl Ramirez GPG Key: http://trinipino.com/PublicKey.asc -------------- next part -------------- A non-text attachment was scrubbed...
