git commit: Summary: Fix virtual router trying to resolve own host
name
Updated Branches:
refs/heads/master 4572bc068 -> 95df86e1e
Summary: Fix virtual router trying to resolve own host name
Detail: Several virtual router configuration commands, such as iptables
commands, run slowly due to attempting to do a name lookup on the virtual
router's hostname and having to time out. This is seen in the agent logs when
a virtual router command is run, as "unable to resolve host r-410-VM" or
similar. This can make for very slow router configuration, especially as the
number of network rules grows. This change simply sets the router's name to
the localhost IP in /etc/hosts
BUG-ID : NONE
