libvirt-console-proxy received no updates the last 3 years and no longer compiles du to several API changes in upstream projects - the joy of GO. My branch at <file:~phahn/REPOS/VIRT/libvirt-console-proxy> contains several patches to make it compile again, which I also sent upstream: <https://www.redhat.com/archives/libvir-list/2019-November/msg00745.html> To compile it on Debian / UCS-4.4 it needs more work; my branch contains some Debianization WIP, but "golang-glase" as contained in Debian-Stretch does not work - use the latest version from <https://github.com/Masterminds/glide#install> Using "glade mirror" to setup an alias for "libvirt.org/libvirt-console-proxy" did not work; therefore my branch has [debian/sid] 6b32369 Update GIT repository to github.com Makefile Put everything below ~/go/src/ and hope for the best.

UVMM and virtualization with UCS is deprecated and will no longer be developed in UCS 4.4; they have already been removed from UCS 5.0. |
We are currently using websockify as the service where novnc connects to. websockify provides the VNC protocol over a websocket. qemu already supports this by itself: <graphics type='vnc' port='5900' autoport='yes' websocket='5700' listen='0.0.0.0' keymap='de'> <listen type='address' address='0.0.0.0'/> </graphics> The <graphics> tag has an attribute websocket. With websocket='-1' it will create such vnc-over-websocketservice and assigns a port. This works already quite well: …/novnc/vnc_auto.html?host=myqemu.host.local&port=5700 But not every virtualization server is available in the networks used by customers. Therefore there is the libvirt-console-proxy projects, which is just a websocket proxy to the qemu websockets. We should replace the current websockify process with such a libvirt-console-proxy. Unfortionately currently there are no debian packages yet for libvirt-console-proxy (or I didn't find any). It's written in go, we could package it ourself, but I think this is not worth the efford right now.
