lang=EN-US><FONT size=3><FONT face=Calibri>Hi, I have setup the openstack cloud
and launched VMs in the cloud. At first everything went very well. But yesterday
evening, due to some reasons our lab lost power and all servers were shutdown.
This morning I turned on all nodes and try to connect to the VM by ssh but
failed. I used netstat to check the status of port 22. It shows that connection
between VM and machine in the external network can be established. However the
ssh process just stuck at SSH2_MSG_KEXINIT sent. Also I setup a rabbitmq server
in the VM and the same situation happened. When connecting rabbitmq server
through web ui, netstat shows that connections have been established however the
web browser can not get any data from the server, it shows a blank page. Also I
tried to ssh from one VM to another VM through internal network, the
192.168.1.0/24 network, similar things happened. Does anyone know how to fix
this problem? Thank you! By the way the br-ex bridge can only be brought up
manually, so after boot the network node I brought up the br-ex bridge and
restart all relevant network services in network node. Please help me with this
problem. Thank you very much!!</FONT></FONT></SPAN></P>
