Thanks for the help. The issue ended up being due to the nfs v4 Domain.

Could you follow the link(https://cwiki.apache.org/CLOUDSTACK/kvm-agent-debug.html):
Which KVM host os is using? Centos 6.2, 6,1, Ubuntu 10.04? 
Which version of libvirt is using, "virsh --version"
turn the agent log level to debug: sed -i 's/INFO/DEBUG/g' /etc/cloud/agent/log4j-cloud.xml

Then reproduce  the issue, and take a look at agent.log.
