Hello Jakub, could you please provide more information about your deployment? Especially: - Is ovirt-websocket-proxy running on your engine machine? - Is it configured correctly? - Do you have engine's CA imported in your browser (i.e. you are not adding a security exception on each browser session)? For now I can point you to oVirt wiki testing pages: - http://www.ovirt.org/Features/SpiceHTML5#Testing - http://www.ovirt.org/Features/noVNC_console#Testing The configuration really depends on your deployment, but from the testing cases (especially noVNC one) you should get the idea how it's done. In any case feel free to ask me about additional info. Regards, Franta. ----- Original Message ----- From: "Jakub Bittner" <j.bittner(a)nbu.cz&gt; To: users(a)ovirt.org Sent: Tuesday, August 27, 2013 12:21:34 PM Subject: [Users] spice-html5 black screen Hi, I've installed spice-html5 on centos 6.4 by yum --enablerepo=epel-testing install spice-html5 but if I open ovirt wui nd select spice-html5 and click on console it opens new window and i got only black screen.
