  In the network.log file, I got following messages:

  The network info is empty, and on this compute node, the br100 and
  dnsmasq process can not be started automatically.

  Have any idea about this? need I create the bridge manually?


  I find the root cause is:
  When I try to create network the vlan is set by default and it will be filtered out under FloatDHCP mode. 

  And there are no any friendly messages or document to show me what
  happened when I create network or launch instance.
