minishift: Locally installed dnsmasq server causes DNS lookups to fail for instances using the xhyve driver

err     : exit status 70
output  : Registering to: subscription.rhsm.redhat.com:443/subscription
Network error, unable to connect to server. Please see /var/log/rhsm/rhsm.log for more information.

I tried to start it using this command to have more information 
minishift start -v 5 --show-libmachine-logs
but not real additional information.
Except the version of subscription-manager

sudo -E subscription-manager version
SSH cmd err, output: <nil>: server type: This system is currently not registered.
subscription management server: Unknown
subscription management rules: Unknown
subscription-manager: 1.19.23-1.el7_4
python-rhsm: 1.19.10-1.el7_4

by using minishift ssh I checked the /var/log/rhsm/rhsm.log

see here https://gist.github.com/dwojciec/c05459256b0016214883ea52ae62cf21

any helps are welcome

Thanks again for all your help.

@sensadrome The error about seeing a password should be filed against CDK, http://issues.jboss.org/ This is likely do to the way libmachine handles the ssh command (as it fails, it dumps it). Seems we didn’t find all the cases…

I am also seeing this error - and can confirm that either stopping the local dnsmasq server or making it listen on all interfaces (listen-address=0.0.0.0) will alleviate the issue (presumably the latter is not desired since it will break any internal dns?).

It should also be noted that the error is reported in the console and spits out the RHN password which is, presumably, not desirable.
