Re: network problem

 

Hi Vish

Here is .....


Controller (nova.conf)
network_manager=nova.network.manager.FlatDHCPManager
force_dhcp_release=True
dhcpbridge_flagfile=/etc/nova/nova.conf
firewall_driver=nova.virt.libvirt.firewall.IptablesFirewallDriver
my_ip=63.55.xx.x2
public_interface=eth0
vlan_interface=eth1
flat_network_bridge=br100
flat_interface=eth1
fixed_range=10.10.10.0/24
auto eth0
iface eth0 inet static
        address 63.55.xx.x2
        netmask 255.255.255.128
        gateway 63.55.xx.x1

auto eth1
iface eth1 inet static
---------------------------------------------------------------------------------------------


Compute (nova.conf)
network_manager=nova.network.manager.FlatDHCPManager
force_dhcp_release=True
dhcpbridge_flagfile=/etc/nova/nova.conf
firewall_driver=nova.virt.libvirt.firewall.IptablesFirewallDriver
my_ip=63.55.xx.x3
public_interface=eth0
vlan_interface=eth1
flat_network_bridge=br100
flat_interface=eth1
fixed_range=10.10.10.0/24
auto eth0
iface eth0 inet static
        address 63.55.xx.x3
        netmask 255.255.255.128
        gateway 63.55.xx.x1

auto eth1
iface eth1 inet static

-------------------------------------------------------------------------------------------------
Here is the command of network
nova-manage network create --label=myNetwork
--fixed_range_v4=10.10.10.0/24--bridge=br100 --num_networks=1
--multi_host=T

Best Regards,

Umar
