Cloudstack VR does not resolve to DNS queries
Dear Team,
VR been created while creating a VPC, VR is not able to resolve any DNS queries made directly from VR itself. While I am able to reach 8.8.8.8 and 4.2.2.2 but while querying DNS services it says connection timed out.
Any suggestions why?

Vivek,
Can you confirmed the mapping if nic on the VR:
eth0 for cloud_link_local
eth1 for public traffic
eth2+ private networks
Also make sure their are properly mapped on xenserver, if you have a
network connectivity issue it could be related to the mapping between
networks in XenServer and Labels in CloudStack at the zone definition.
from the VR can you ping 8.8.8.8 ? can you get an answer for "dig yahoo.com
@8.8.8.8" ?
Does the VPC use custom ACL's ?
Cheers,

because i never tried to patch these codes before.
what i have replaced with original:

ok, we've run into this before. It's related to SNAT rules being put in out of order due to the wrong ip in the databag. I believe it was patched fairly recently and may not be rolled into a release yet.
What ACS release are you attempting to use?
The fix is here I believe: https://github.com/myENA/cloudstack/commit/82a9aa0c18559026e20644ba32fa1aeb97f2b6a6

Can you check the routing table on the VR? If you populated the internal dns box when you setup the zone, ACS will create a route pointing traffic to the inside interface. This will cause asymmetric routing and cause the firewall to drop packets.
