Hyper-V Requirements:      A hypervisor has been detected. Features required for Hyper-V will not be displayed.

Steps to reproduce

1. start a simple container: oc run -it busybox --image=busybox:latest – sh (this (and other) container’s /etc/resolv.conf points to dns-default service IP)
2. run nslookup secure-feeds-production-us-east-1-761931097553.s3.us-east-1.amazonaws.com
3. run nslookup against other hosts, e.g. cnn.com
4. run both 2. and 3. inside pod in openshift-dns project (which backs dns-default service) and inside the node (both have their /etc/resolv.conf pointed at an IP that presumably points/maps outside the cluster on tap0 interface), or on the VM host or another VM on that host: both names are resolved

Expected

both names should be resolved from within a container

Actual

resolving the amazon s3 link fails: Server: 10.217.4.10 Address: 10.217.4.10:53 Non-authoritative answer: *** Can’t find secure-feeds-production-us-east-1-761931097553.s3.us-east-1.amazonaws.com: No answer

resolving other names works: Server: 10.217.4.10 Address: 10.217.4.10:53 Non-authoritative answer: Non-authoritative answer: Name: cnn.com Address: 151.101.195.5 Name: cnn.com Address: 151.101.3.5 Name: cnn.com Address: 151.101.67.5 Name: cnn.com Address: 151.101.131.5

Logs

I’ll follow up with the below later if needed, as I need to keep the cluster alive for another purpose for a while …

Before gather the logs try following if that fix your issue

$ crc delete -f
$ crc cleanup
$ crc setup
$ crc start --log-level debug

Please consider posting the output of crc start --log-level debug on http://gist.github.com/ and post the link in the issue.
