nova-spiceproxy ignores spicehtml5proxy_host setting = "::"

[Thiago Martins]

Hello Stackers!

I'm trying SPICE Consoles and it is working smoothly! But, I detected a problem, it is ignoring the entry "spicehtml5proxy_host" in nova.conf for Dual-Stacked environment (IPv4 / IPv6).

So, it isn't listening on "::".

The following setup doesn't work....

---
[spice]
enabled = True
spicehtml5proxy_host = ::
html5proxy_base_url = http://controller.yourdomain.com:6082/spice_auto.html
keymap = en-us
---

Unless I patch the following file:

/usr/lib/python2.7/dist-packages/nova/cmd/spicehtml5proxy.py into this:

---
opts = [
    cfg.StrOpt('spicehtml5proxy_host',
               default='::',
               help='Host on which to listen for incoming requests'),
---

As you guys can see, I replaced the default "0.0.0.0" to "::" and now SPICE Proxy listens on both IPv4 and IPv6! But, this is a hack...

I don't know why it is ignoring the "spicehtml5proxy_host = ::" entry at nova.conf.

BTW, the "novncproxy_host = ::" works as expected for NoVNC but, I'm disabling VNC from my cloud in favor of SPICE.

Cheers!
Thiago

Hi!

This problem still exists on Juno 2014.2, look:

---
root@controller-1:~# netstat -natup | grep 6082
tcp 0 0 0.0.0.0:6082 0.0.0.0:* LISTEN 7182/python

root@controller-1:~# sed -i 's/0.0.0.0/::/' /usr/lib/python2.7/dist-packages/nova/cmd/spicehtml5proxy.py

root@controller-1:~# service nova-spiceproxy restart
nova-spiceproxy stop/waiting
nova-spiceproxy start/running, process 7234

root@controller-1:~# netstat -natup | grep 6082
tcp6 0 0 :::6082 :::* LISTEN 7234/python
---

---
root@psuaa-1:~# dpkg -l | grep -i nova-spiceproxy
ii nova-spiceproxy 1:2014.2-0ubuntu1~cloud0 all OpenStack Compute - spice html5 proxy
---

I'm using:

---
add-apt-repository ppa:ubuntu-cloud-archive/juno-staging
---

...with Trusty.

What am I missing?

Tks!
Thiago

Did you add html5proxy_{host, port} under the [Spice] section in the /etc/nova/nova.conf ?

The name of the setting has been changed from spicehtml5proxy_{host, port} to html5proxy_{host, port}
