Description of problem

For some reason I have to open a tcp listening socket when running the kata container. I made some changes to the kata runtime: --- a/vendor/github.com/intel/govmm/qemu/qemu.go +++ b/vendor/github.com/intel/govmm/qemu/qemu.go @@ -1798,6 +1798,9 @@ func (config *Config) appendKnobs() { if config.Knobs.Stopped == true { config.qemuParams = append(config.qemuParams, "-S") } +
+ config.qemuParams = append(config.qemuParams, "-qmp") + config.qemuParams = append(config.qemuParams, "tcp:127.0.0.1:4444,server,nowait") }

func (config *Config) appendBios() {

Then using the new kata runtime to start a kata container but I can not find the listening port in the host. I added some log in the qemu where the listening socket is created and confirmed the socket is established successfully. But can not be seen from host. Seems the connection was isolated？

Expected result

we can see the listing port using netstat -ntlp something like: Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 127.0.0.1:4444 0.0.0.0:* LISTEN 69446/qemu-system-x

Actual result

there's NO listening socket to 127.0.0.1:4444
