I am trying to do the network setup in the openstack configuration on 3 Ubuntu vm with vmware workstation, but in order to work I get the following indication : If you are building your OpenStack nodes as virtual machines, you must configure the hypervisor to permit promiscuous mode on the external network.

I know that with vcenter I can configure the vswitch in promiscous mode but how can i do this with workstation ? Vmware workstation is running on a windows 7

Try below in ubuntu:

$ sudo vi /etc/network/interfaces


auto lo

auto eth0 iface eth0 inet static address netmask gateway dns-nameservers

auto eth1 iface eth1 inet manual up ifconfig $IFACE up up ip link set $IFACE promisc on down ip link set $IFACE promisc off down ifconfig $IFACE down

To check if the promisc is on

$ip a |grep eth1 |grep PROMISC

To configure the promiscous mode, you have to do that "before you open vmware workstation" -->

For ubuntu ...

rm -rf /lib/udev/devices
mkdir /lib/udev/devices
cp -rp /dev/vm* /lib/udev/devices/
chmod a+rw /lib/udev/devices/vm
chmod a+rw /dev/vm

you can put these commands in a script file and execute it [use sudo]

check the original answer on vmware website

put three things in mind
- its slightly different for some linux distros ...
- do that before you open vmware workstation
- its not permenant, so you have to do it everytime

Thats how it works for me. Good luck
