VDSM not starting, RHEL 6.3 and RHEV3.0

I opened up a support Ticket but wanted to see if there was any folks having similar issues - 

I installed the hypervisor software on RHEL and everything went successfully. When the server was rebooted vdsmd did not start. Upon some troubleshooting I tried to start it on my own and got the following message. We are using RHEV3.0 and RHEV on RHEL6.3 cvlqrhevnwm5:/root #

service vdsmd start

vdsm: libvirt already configured for vdsm [ OK ]

Starting iscsid:

vdsm: Failed to define network filters on libvirt [FAILED]
