the System Virtual Machine

@weizhouapache 
Hi. I can connect to SSVM via the virsh console. There is an entry in the logs 
/var/log/cloud.log:
```

```
But port 8250 exists on the host.
```
netstat -anp | grep -i 8250
tcp6 0 0 192.168.3.55:8250 192.168.3.55:34584 TIME_WAIT -
```
However, when connecting via telnet, there is no connection. 
```
root@s-16-VM:~# telnet 192.168.3.55 8250
Trying 192.168.3.55...
telnet: Unable to connect to remote host: Connection timed out
```
