[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

#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
