[problem phenomenon]

Cf component ccng failed to start, prompting the following message:-STARTING cloud_controller_ng_ctl at Thu Sep 11 07:33:05 UTC 2014-restart: Unknown instance: mount.nfs: DNS resolution failed for 0.nfs-server.default.cf-180.microbosh: Name or service not known

[cause of the problem]

Cf component Job virtual machine parses the address of the machine where other components are located from the powerdns of MicroBosh. From / etc/resolv.conf, you can see that nameserver points to the virtual machine where MicroBosh resides. However, the virtual machine did not get the machine IP from PowerDNS. The reason is that the MicroBosh firewall is set and the DNS port 53 is opened.
