[Kimchi-devel] [PATCH] [Kimchi 4/6] Implement the web serial console front-end
Jose Ricardo Ziviani
joserz at linux.vnet.ibm.com
Thu Feb 4 19:47:27 UTC 2016
- This is the screen that opens when the client requests the serial
console, basically a textarea and a websocket that communicates
with the server (through websockify) in order to send/receive
data from a guest serial console.
