Hi,

I am trying to test Openstack on VirtualBox. I have created two VMs, one for controller, and one for compute.

On my HOST machine ifconfig:

wlp1s0    Link encap:Ethernet  HWaddr 08:d4:0c:ac:c1:1e  
          inet addr:192.168.0.110  Bcast:192.168.0.255  Mask:255.255.255.0
          inet6 addr: fe80::14c9:51d1:67c3:7c0b/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:40584 errors:0 dropped:0 overruns:0 frame:0
          TX packets:25193 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:28161704 (28.1 MB)  TX bytes:3852137 (3.8 MB)

and ip route:

default via 192.168.0.1 dev wlp1s0  proto static  metric 600  
192.168.0.0/24 dev wlp1s0  proto kernel  scope link  src 192.168.0.110  metric 600

From VirtualBox GUI I set on each VM machine:

  • first adapter: Internal network (for management network, just to communication between two VMs)
  • second adapter: bridge from my HOST wlp1s0 interface
  • third adapter: NAT (just for Internet connection inside VMs)

Interface configuration on these VMs I set as follows:

# The loopback network interface
auto lo
iface lo inet loopback

# Management (internal network)
auto enp0s3
iface enp0s3 inet static
  address 10.0.0.11
  netmask 255.255.255.0

# Bridge from my HOST wlp1s0 (I configure it here as "provider" network from openstack documentation)
auto enp0s8
iface enp0s8 inet manual
  up ip link set dev $IFACE up
  down ip link set dev $IFACE down

# NAT (for internet access on VM)
auto enp0s9
iface enp0s9 inet dhcp

ifconfig from VM (e.g, controller):

enp0s3    Link encap:Ethernet  HWaddr 08:00:27:28:fa:b4
