This just happened for the third time. In every machine I try to install Openstack, it suddenly can't connect to any external address after I install Nova (even after it just downloaded the packages), not to mention it gets very slow. I was using a server machine though SSH, and this was the output it gave when it executed the command apt-get install -y nova-api nova-cert nova-conductor nova-consoleauth nova-novncproxy nova-scheduler python-novaclient nova-compute nova-console:

and it goes on like this. I found it strange and tried to run an apt-get update and ping some websites. But it failed. the apt-get update gave the same error messages as above. Then I tried rebooting the machine, and now I can't connect to it via SSH anyome. It prints

ssh: connect to host 10.129.4.18 port 22: No route to host

Did anyone here had this kind of problem too? What can I do in this situation?
