Title:
  Multi host DHCP networking and local DNS resolving

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  I have a multi host environment with VLAN networking running and all
  works fine except DNS resolving between instances on different compute
  nodes.

  For example assume that there are 3 instances running (call them x, y
  and z) and 2 of them run on compute node A (x,y) and the third
  instance (z) runs on node B. The VMs x and y can access each other via
  their assigned DNS names (respectively x.novalocal and y.novalocal)
  but the VMs can not resolve the DNS for the third one (z.novalocal).
  And vice versa, the VM y cannot resolve VMs x and y.

  Problem here is that each compute node has his own dnsmasq and mange
  its own local DNS entries but other compute nodes does not know how to
  access this information.

  The workaround is to setup some external DNS if I want resolution
  between hosts.
