Attached Firefox and Chrome screenshots of Certificates. errors thrown by websockify Firefox: 1: handler exception: [Errno 1] _ssl.c:1359: error:14094418:SSL routines:SSL3_READ_BYTES:tlsv1 alert unknown ca Chrome: 11: handler exception: WSRequestHandler instance has no attribute 'last_code' For Firefox it looks like firefox needs a bit of proding to get it to accept the Websocket CA Cert: https://github.com/kanaka/websockify/issues/34 The error generated by chrome seems to be a websockify issue: https://github.com/kanaka/noVNC/issues/86 https://github.com/kanaka/websockify/issues/22#issuecomment-3263065 https://github.com/kanaka/noVNC/issues/177 In any event I got both Chrome and Firefox working by manually browsing to: https://ENGINEFQDN:6100 and accepting the self signed cert Not pretty but it worked. - DHC On Thu, Aug 1, 2013 at 2:08 PM, Alon Bar-Lev <alonbl@redhat.com> wrote:

That did the trick for getting the websocket proxy configured ( i backed out all my changes prior to running engine-setup). I do notice that it still seems to leave the ovirt-websocket-proxy.conf in it's default state and makes no dedications to it. Instead it generated /etc/ovirt-engine/ovirt-websocket-proxy.conf.d/10-setup.conf
I also noted engine setup generated: /etc/pki/ovirt-engine/certs/websocket-proxy.cer /etc/pki/ovirt-engine/keys/websocket-proxy.p12 /etc/pki/ovirt-engine/keys/websocket-proxy.key.nopass /etc/pki/ovirt-engine/requests/websocket-proxy.req
None the less still neither spice nor novnc will connect. I tried changing Engine:6100 to EngineIP:6100 so that IP would be used instead. However using either the FQDN or IP still yielded the same results.
You should not touch anything... all should be configured... Make sure your browser trust the *CA* of the engine and not the engine certificate directly. And try to open vnc console via webadmin.
There was nothing interesting in the logs either. I do notice that whilst the websocket-proxy service is running I never see an websockify processes but instead in /var/log/messages I see: Aug 1 13:44:10 ovirtfoo ovirt-websocket-proxy.py[435]: 11: handler exception: [Errno 1] _ssl.c:1359: error:14094418:SSL routines:SSL3_READ_BYTES:tlsv1 alert unknown ca
Thus I changed SSL_ONLY=True to SSL_ONLY=False in /etc/ovirt-engine/ovirt-websocket-proxy.conf.d/10-setup.conf and restarted engine and websocket-proxy No dice it still generated the same error as above during an attempted connection to /var/log/messages
I also not the following error message at VM power off (albeit I am guessing it has nothing to do with this issue): 2013-08-01 13:41:03,742 ERROR [org.ovirt.engine.core.vdsbroker.DestroyVmVDSCommand] (pool-6-thread-50) [304efb3e] VDS::destroy Failed destroying vm fec3260c-871a-4fbe-a006-9eee4fbfbbcc in vds = 5713e5c8-6252-4bce-a3f6-bbd8e1e6eb57 : ovirtnodefoo, error = org.ovirt.engine.core.vdsbroker.vdsbroker.VDSErrorException: VDSGenericException: VDSErrorException: Failed to DestroyVDS, error = Unexpected exception

If you install the proxy on the engine machine you just need:
# yum install ovirt-engine-websocket-proxy # engine-setup
then answer yes when prompt if you like to configure websocket proxy.
you can execute engine-setup again even if you already installed.

After Referencing: http://www.ovirt.org/Features/noVNC_console http://www.ovirt.org/Features/SpiceHTML5
and looking at some of the related engine code.
I am still attempting to get the spice/novnc browser based consoles to work.
I am working from a build from master yesterday I used to upgrade over a previous 3.3 master build from about a month back.
VDSM version on host is 4.12.0 built minutes ago.
I have installed and configured the websocket proxy like so:
Set WebSocketProxy to engine ENGINEIP port 6100 engine-config -s WebSocketProxy=ENGINEIP:6100
/usr/share/ovirt-engine/bin/pki-enroll-pkcs12.sh --name=websocket-proxy --password=install --subject="/C=US/O=DHC/CN=ENGINEFQDN"
This generates: /etc/pki/ovirt-engine/keys/websocket-proxy.p12 /etc/pki/ovirt-engine/certs/websocket-proxy.cer /etc/pki/ovirt-engine/requests/websocket-proxy.req
However it does not generate the key that websockify wants so we do: openssl pkcs12 -in websocket-proxy.p12 -nocerts -nodes -out /etc/pki/ovirt-engine/keys/websocket-proxy.key
The configuration of ovirt-websocket-proxy: PROXY_HOST=* PROXY_PORT=6100 SOURCE_IS_IPV6=False SSL_CERTIFICATE=/etc/pki/ovirt-engine/certs/websocket-proxy.cer SSL_KEY=/etc/pki/ovirt-engine/keys/websocket-proxy.key FORCE_DATA_VERIFICATION=False CERT_FOR_DATA_VERIFICATION=/etc/pki/ovirt-engine/certs/engine.cer SSL_ONLY=True TRACE_ENABLE=False TRACE_FILE= ENGINE_USR="/usr/share/ovirt-engine"
Install spice-html5 git clone http://anongit.freedesktop.org/git/spice/spice-html5.git mv spice-html5 /usr/share
Test spice: In Webadmin UI we set create a VM, set display as spice, start it and set it's console to spice-html5. Result spice-html client opens in a new tab but does not connect.

I verified connection of both the spice/vnc console directly at the host level with a quick connect via virt-viewer.
A quick scan with nmap of engine and host to verify sockets are open:
Nmap scan report for engine Host is up (0.0042s latency). Not shown: 995 closed ports PORT STATE SERVICE 22/tcp open ssh 80/tcp open http 111/tcp open rpcbind 443/tcp open https 6100/tcp open synchronet-db
Nmap scan report for host Host is up (0.0045s latency). Not shown: 997 closed ports PORT STATE SERVICE 22/tcp open ssh 111/tcp open rpcbind 5900/tcp open vnc
For grins I stopped the websocket proxy and manually started a websockify like so: websockify 3.57.111.11:6100 3.57.111.12:5900 --cert=/etc/pki/ovirt-engine/certs/websocket-proxy.cer --key=/etc/pki/ovirt-engine/keys/websocket-proxy.key
WARNING: no 'numpy' module, HyBi protocol is slower or disabled WebSocket server settings: - Listen on ENGINEIP:6100 - Flash security policy server - SSL/TLS support - proxying from ENGINEIP:6100 to HOSTIP:5900
Attempting another connection via
https://ENGINEFQDN//ovirt-engine-novnc-main.html?host=ENGINEIP&port=6100
results in:
1: handler exception: [Errno 1] _ssl.c:1359: error:14094418:SSL routines:SSL3_READ_BYTES:tlsv1 alert unknown ca
I should also note in case it matters that the SSLEnabled=false, and EnableSpiceRootCertificateValidation are both set as false are set in my engine options.
Am I doing something wrong here, I don't see any reason this should not work?
