How to set 'search' and 'domain' options in instances' resolv.conf by Eucalyptus

This question is a duplicate of #106169 (https://answers.launchpad.net/ubuntu/+source/eucalyptus/+question/106169)

Hello,

I experience the following problem:
when I start an instance of Lucid image it gets the hostname like ip-192-168-1-2. Later when I do
$ sudo apt-get update

I get the message
sudo: unable to resolve host ip-192-168-1-2

Actually I can fix this by changing resolv.conf to:
domain vtcloud. # my private dns zone
search vtcloud
nameserver 192.168.1.1 # my private dns with 'vtcloud' zone configured and A-record for ip-192-168-1-2.vtcloud.

Previously resolv.conf looked like:
nameserver 127.0.0.1 # injected by Eucalyptus
nameserver 192.168.1.1 # injected by Eucalyptus according to my dns configuration in Web-UI of UEC

Nevertheless, a few minutes later my new resolv.conf is reverted to default configuration by Eucalyptus.

So, I just want to find out Is there any way to set 'domain' and 'search' options in instances' resolv.conf automatically by Eucalyptus?

Thank you.
