Bug Description
Multiple NIC/subnet may attach to a VM instance, if both subnets provide dns servers, only the last one will be used (overrides the previous one), so we need a method to disable dns server on some subnets.

Wouldn't you have the same problem with the router option provided by the DHCP server?
I think DNS server options are not sent for a subnet if there are no DNS servers there.
In cases like the following:
hosts A,B,C with A on S1, C on S2 and B on S1 and S2, then globally disabling DNS for S2 (for instance) is not a solution. However, I don't see any criterion for specifying which of the two DNS servers B should use.
Do you have already in mind a strategy?
