My previous installation had issues with the TLS certificate time of issue, which was successfully fixed in this version (https://bugzilla.redhat.com/show_bug.cgi?id=1210486). However, when trying to start the SPICE HTML5 client, all I can see is the grey square and no activity, and when clicking on "Toggle messages output", the error message "Unexpected protocol mismatch" is shown. >>>>> Things done: >>>>> * ovirt-guest-agent installed on the VM >>>>> * On client side, updated browser (Firefox) to latest version (38.0) and /ca.crt has been imported into Firefox certs >>>>> Regarding logs on the server side, I can see the following: >>>>> ovirt-engine >>>>> ============ >>>>> 2015-06-16 10:49:29,862 INFO [org.ovirt.engine.core.bll.SetVmTicketCommand] (ajp--127.0.0.1-8702-11) [39c79276] Running command: SetVmTicketCommand internal: false.

Hi Michal, Unfortunately downgrading didn't do the magic this time :-( We finally decided to use noVNC (which we had to downgrade as well, currently using novnc-0.4-7.el7.noarch) and it fulfills our needs so far, so we'll keep it.

Thanks for all the help!
