OpenStack Installation on VMware with one interface card Possible ???

OpenStack installation works good on VMware ESX/ESXi 4.1 or later.
One physical NIC server would be enough.

For flags, you can refer to readme at http://nova.openstack.org/vmwareapi_readme.html
on ESX/ESXi server, you do not need to edit any file like /etc/network/interfaces.

Here is nova.conf from a working setup,

nova.conf file:
--daemonize=1
--dhcpbridge_flagfile=/etc/nova/nova.conf
--dhcpbridge=/opt/openStack/bin/nova-dhcpbridge
--lock_path=/tmp
--logdir=/var/log/nova
--state_path=/var/lib/nova
--verbose
--network_manager=nova.network.manager.FlatManager
--sql_connection=mysql://root:password@127.0.0.1/nova
--rabbit_host=127.0.0.1
--ec2_host=127.0.0.1
--image_service=nova.image.glance.GlanceImageService
--glance_api_servers=127.0.0.1:9292
--use_s3=false
--connection_type=vmwareapi
--vmwareapi_host_ip=10.0.120.11
--vmwareapi_host_username=root
--vmwareapi_host_password=password
--vmwareapi_wsdl_loc=http://10.0.120.9:8080/vimService.wsdl
--console_manager=nova.console.vmrc_manager.ConsoleVMRCManager

Thanks for your kind reply ... I installed the Openstack Nova on VMware successfully..

now i don't know how to solve this problem.. :(

First of all your command is incorrect.

it should be 1 256.

To fix the issue, add --flat_network_interface=eth0 to your flagfile or specify your interface in the command with
nova manage network create 192.168.3.0/24 1 256 --bridge_interface=eth0

or --vlan_interface in your flagfile if you are using vlan mode

Thanks for your quick and kind response...i run this command
nova-manage network create 192.168.3.0/24 1 256 --bridge_interface=eth0

Now it shows the following output in logfile
(nova): TRACE: ValueError: The network range is not big enough to fit 256. Network size is 1

apt-get install bridge-utils

sudo brctl addbr br100

maybe this will help you ..
