Hi. After follow this tutorial https://www.mirantis.com/how-to-install-openstack/ (https://www.mirantis.com/how-to-insta...) I have a working environment.

Four machines was created in my VirtualBox. 3 nodes and the master. All working as espected.

But my host machine ( Windows host of VirtualBox environment ) was lost the internet connection until I drop the master, when I have my internet back.

I have made no changes in any config file and not touch anything. Just ran the script as indicated in Cygwin env.

My home network range is ... 255 My gateway is

I've found the master node somehow have catched my gateway IP because I can't go to my ISP modem ( while the master node is up. This IP leads me to the master's panel page.

When I down the master node all is back to normal.

Is it normal? How can I access the master from other machine?


After reinstall I can see the Adapter #2 is taking my home network...

Creating host-only interface...
Interface VirtualBox Host-Only Ethernet Adapter #2 was successfully created
Disabling DHCP server on interface: VirtualBox Host-Only Ethernet Adapter #2...
Configuring IP address and network mask on interface: VirtualBox Host-Only Ethernet Adapter #2...
Verifying interface VirtualBox Host-Only Ethernet Adapter #2 has IP and mask properly set.

Even I don't touch the config file:

# Please add the IPs accordingly if you going to create non-default NICs number
#   - Mirantis OpenStack Admin network
#  - OpenStack Public/External/Floating network
#  - OpenStack Fixed/Internal/Private network
# - OpenStack Management network
# - OpenStack Storage network (for Ceph, Swift etc)

Why? someone?
