Title:
  hyper-v: DNS Server settings are not getting injected inside Ubuntu
  13.10 during Failover and Test-Failover

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  [HyperV Replica :: http://technet.microsoft.com/en-us/library/jj134172.aspx]
  [Guest IP Injection :: http://blogs.technet.com/b/virtualization/archive/2012/05/29/inject-ip-address-into-the-vm-during-failover.aspx]

  DNS server settigns are not getting injected inside Ubuntu 13-10 for a
  network adapter that is attached to an external network before
  Failover and is configured using static Guest IP injection during
  Failover. The settings are updated correctly inside
  /etc/network/interfaces.

  The DNS server entries updated to specified values after next reboot.

  1 Create anUbuntu-13.10 VM with external network attached to it.
  2 Check DNS entries
  cat /etc/resolv.conf
  # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
  #     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
  nameserver X.Y.Z.W
  nameserver X.Y.Z.K
  search dummy.fake.com

  3 Enable Replication.

  4 Set Failover IPv4 (static IP) settings.
  Set-VMNetworkAdapterFailoverConfiguration -ComputerName bharatl-test1 -VMName lol -IPv4Address 192.168.100.10 -IPv4SubnetMask 255.255.255.0 -IPv4PreferredDNSServer 192.168.100.101 -IPv4DefaultGateway 192.168.100.1 -VMNetworkAdapterName 'Network Adapter'

  5 Do Failover.

  6 Check DNS settings.
  cat /etc/resolv.conf
  # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
  #     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
  nameserver X.Y.Z.W
  nameserver X.Y.Z.K
  search dummy.fake.com

  7 Reboot the Guest.

  8 Check DNS settings
  # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
  #     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
  nameserver 192.168.100.101
