This is the initial version of a web serial console for kimchi/libvirt
VMs.
When a VM is turned on, a new action is displayed named "Connect
Serial", this will open a new tab with an interface like the existing
novnc.
That interface opens a websocket to kimchi webserver (nginx), then
it is redirected to websockify. Websockify will proxy that connection to
a local unix socket server to finally communicate with the guest
console.
I chose to create one server per guest because that's the way websockify
was designed (it was born inside novnc), so I could reuse the token
security plugin implemented in websockify. In order to avoid wasting
resources I decided to user unix socket, a local/lightweight/reliable
socket if compared with internet sockets, this uses files instead of
ports to accept connections.
When a connection is established no one else can get that console (I'm
not multiplexing it but it's possible in future). The serial console
will be available again if the current user does one of:
- type ctrl+q
- close the tab
- 2 min. timeout
Thanks
