I installed devstack on a laptop (Ubuntu 16.04).

I did a default installation. After typing ./stack.sh - the installation is completed. I am able to access the Horizon GUI on the same host and work with it (create networks, launch VMs...) BTW, I needed to have only one change NOVNC_BRANCH=0.6.0 was required to be able to access the console of the launched VMs.

There is however, a different problem. The host DNS stops working. The host is able to ping the external network (i.e. laptop's own Ethernet NIC) - only the DNS fails. Host DNS begins to work as soon as I run ./unstack.sh.

I suspect this has to do with the dnsmasq configuration in /etc/neutron/dhcp-agent.ini...

/etc/resolv.conf is not changed before or after..

Any tips?
