[Qemu-devel] [Bug 1724477] Re: Build-in websocket broken since v2.9.0-rc0

[Daniel Berrange]

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.
