From: "David Li" <david_li(a)sbcglobal.net&gt; To: users(a)ovirt.org Cc: "david li" <david_li(a)sbcglobal.net&gt; Sent: Tuesday, January 28, 2014 7:41:26 PM Subject: [Users] Notes on setting spice-proxy console option Hi, I have struggled quite a bit to get it up and running. Over the time, I have accumulated some notes on various things I did so to share with everyone who is interested in doing this. This complements the online doc in a way that might give me a complete picture in one place. However I need some clarifications as I might have forgotten to document certain steps or certain steps I did turn out to be not necessary in the end. It will be great if experts here can help me get the things straight. My setup is like: Browser (firefox 24.2 on RHEL6) ------------ ovirt-engine (3.3.2) ------------ ovirt-node (3.0.3) No direct network connectivity from the browser machine to the node machine. These are the major things I installed for spice-proxy to work:     * On ovirt-engine:        yum install spice-gtk, virt-viewer, spice-xpi

       yum-install squid       /etc/squid/squid.conf updates:     acl localhost src <browser IP addr>         #http_access deny CONNECT !SSL_ports

        http_access deny !Safe_ports         http_port 3128             service squid restart        make sure iptables allow 3128        engine-config -s SpiceProxyDefault= http://<ovirt-engine-IP>:3128        service ovirt-engine restart        *  On browser machine running firefox 24.2.0 on RHEL6 for running browser    console plugin client       yum install spice-xpi.

      make sure VM's console option is set to SPICE        Are the above steps reasonable? any missing or redundant?

Additional questions: 1. Will spice-proxy work with the Spice HTML5 client in the browser?

2. Is the spice-proxy architecture diagram like:  browser --------- squid proxy - spice-proxy ---------------------- VM

3. I didn't explicitly install any certs for the squid proxy. Is it automatically taken care of?

Another question: In my spice-xpi console window, I can't get out of it by SHIFT+F12.  Should I use something else?

I changed the logger.init as you suggested, restrated firefox and launch the spice console. 2. I looked at the spice-xpi.log file but didn't find any trace of "release-cursor"

3. ON the engine machine, I have: SpiceReleaseCursorKeys: shift+f12 version: general 4. What's the xev tool on the VM you want me to run? I can't find such a command.

>> >> 1. Will spice-proxy work with the Spice HTML5 client in the browser? > Probably, but you would need to set the websocket proxy which is part of installation steps for engine as well (I believe). since it's a proxy as well I'd recommend to use it instead of squid, not in addition. By default it's installed on the engine host but it can be deployed anywhere else.
