Build-in websocket broken since v2.9.0-rc0
Since upgrading to 2.9.0, the qemu's build-in websocket was no longer available.
Host: Ubuntu 16.04 LTS
Command-line: /bin/qemu-system-x86_64 -enable-kvm -vnc 0.0.0.0:8,websocket
I have tested the following qemu versions:
master Fail
2.10.1 Fail
2.9.1 Fail
2.9.0 Fail
2.9.0-rc3 Fail
2.9.0-rc0 Fail
2.8.1.1 Pass
2.7.1 Pass
2.6.2 Pass
Note that we tightened up the websocket server impl to validate HTTP requests more strictly. One key change is that the websockets path is required to be empty, while noVNC will default to appending a path - so make sure you change noVNC to have an empty path. Also until GIT master yesterday, there was a bug that prevented it working if the client requested keep-alive, which I see noVNC now does. So if you try git master today, it ought to work.
Awesome! I cleared the path and tried the latest version, now it works!
BTW, is there any other VNC Web Client that I can choose? or noVNC is the one and only?
