Hi, I'm trying to set up Openstack on two computers, and each of
them has only one NIC. I want to set up one computer as control and
compute node, and another as compute node. I want to use vlan mode,
so quantum is needed.<br>
<br>
I'm install Openstack according<br>
<a href="https://github.com/mseknibilel/OpenStack-Grizzly-Install-Guide/blob/OVS_MultiNode/OpenStack_Grizzly_Install_Guide.rst" target="_blank">https://github.com/mseknibilel/OpenStack-Grizzly-Install-Guide/blob/OVS_MultiNode/OpenStack_Grizzly_Install_Guide.rst</a><br>
<br>
After install quantum server in first computer( used as control and
compute node ), I tried to install the "Network Node" functions. The
NIC is configured as follows:<br>
<blockquote># The loopback network interface<br>
auto lo<br>
iface lo inet loopback<br>
<br>
auto eth0<br>
iface eth0 inet static<br>
address <a href="tel:192.168.1.104" value="+911921681104" target="_blank">192.168.1.104</a><br>
netmask <a href="tel:255.255.255.0" value="+912552552550" target="_blank">255.255.255.0</a><br>
gateway 192.168.1.1<br>
dns-nameservers 8.8.8.8<br>
</blockquote>
In the "3.4. OpenVSwitch (Part2)" section of the guide, eth2 is
cnfigured as<br>
<blockquote>
<pre># VM internet Access
auto eth2
iface eth2 inet manual
up ifconfig $IFACE 0.0.0.0 up
up ip link set $IFACE promisc on
down ip link set $IFACE promisc off
down ifconfig $IFACE down
</pre>
</blockquote>
I don't have another NIC. How should I write the interface
configuration file?<br>
And another question , is it possible to use wireless NIC in
quantum?<br>
<br>
thanks<br>
