I did not test novnc, so I can't comment much on this. But from looking
at the code I would be very surprised if the current code for
nova-novncproxy in Icehouse would work with websockify 0.6.0.

I did test the spice proxy and the version from Icehouse does not work
with websockify 0.6.0. Did it work for you?

While I certainly won't oppose a backport of that patch to Icehouse, I'm
don't see much of a dilemma in the short term. As the current status in
Debian unstable with websockify 0.6.0 does not work at all for all proxy
modes (novnc and spice) downgrading is strictly the better alternative
even if there are bugs with novnc and websockify 0.5.1. At least it will
work to some degree again.

Long term I agree that migrating to websockify 0.6.0 is preferable. But
I doubt we will have a compatible version in Icehouse soon.
