Also I found: when I use `socat` to take a qga socket, then I use `socat` to communicate it will got error. But also SOMETIMES, I will not got error and will communicate OK.
If one user take qga socket, another user should got error, is it? But why sometimes, the communicate is OK? 2017-08-25 10:11 GMT+08:00 Sam <batmanu...@gmail.com>: > Hi all, > > I'm using qga to send `route -n` and `ping` command to guest.
