Title:
  hyper-v: IP Injection setting are not correctly populated inside
  Ubuntu 13.10 guest during Failover and Test Failover when using more
  than one interfaces for IP Injection

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]

  After failover only the Injected IP settings of the last interface is
  retained inside /etc/network/interfaces

  Repro Steps:

  1) Create Ubuntu 13.10 virtual machine.
   
  2) Enable Replication.
   
  3) Attach two network adapters on recovery.
  'Network Adapter' and 'Adapter2'
   
  4) Assign Failover IP settings to both these adapters.
   
  Set-VMNetworkAdapterFailoverConfiguration -ComputerName $computerName -VMName $vmname -IPv4Address 192.168.100.10 -IPv4SubnetMask 255.255.0.0 -IPv4PreferredDNSServer 192.168.100.101 -IPv4AlternateDNSServer 192.168.100.102 -IPv4DefaultGateway 192.168.100.1 -VMNetworkAdapterName 'Network Adapter'
   
  Set-VMNetworkAdapterFailoverConfiguration -ComputerName $computerName -VMName $vmname -IPv4Address 192.168.100.20 -IPv4SubnetMask 255.255.255.0 -IPv4PreferredDNSServer 192.168.100.201 -IPv4AlternateDNSServer 192.168.100.202 -IPv4DefaultGateway 192.168.100.2 -VMNetworkAdapterName 'Adapter2'
   
  5) Do Failover.
   
  Check contents of eth0
   
  cat /var/lib/hyperv/ifcfg-eth0
  HWADDR=00:15:5D:38:4E:30
  DEVICE=eth0
  BOOTPROTO=none
  IPADDR0=192.168.100.10
  NETMASK0=255.255.0.0
  GATEWAY=192.168.100.1
  DNS1=192.168.100.101
  DNS2=192.168.100.102
   
  Check contents of eth1
   
  # cat /var/lib/hyperv/ifcfg-eth1
  HWADDR=00:15:5D:38:4E:31
  DEVICE=eth1
  BOOTPROTO=none
  IPADDR0=192.168.100.20
  NETMASK0=255.255.255.0
  GATEWAY=192.168.100.2
  DNS1=192.168.100.201
  DNS2=192.168.100.202
   
  6) Look into contents of /etc/network/interfaces
  # cat /etc/network/interfaces
  # This file describes the network interfaces available on your system
  # and how to activate them. For more information, see interfaces(5).
  # The loopback network interface
  auto lo
  iface lo inet loopback
  # The primary network interface
  auto eth0
  # The following stanza(s) added by hv_set_ifconfig
  auto eth1
  iface eth1 inet static
          address 192.168.100.20
          netmask 255.255.255.0
          gateway 192.168.100.2
          dns-nameservers 192.168.100.201 192.168.100.202
  #End of hv_set_ifconfig stanzas
   
  7) Only IP settings for the last interface i.e., eth1 in our case are intact.
