Hi All,

I am new to Cloudstack I would required your help to achieve my advanced
networking configuration. right now I am using CS-4.4.0 management server
with Mysql DB on it. I have 2 computing server with multiple NICs to test
my environment. As per the study guide I could able to test all the
functionality except my topology point view. Basically I would need my
guest VM to have 2 Physical NICs one towards to Internet (eth0) & VM to VM
communication and other Physical NIC (eth1) for my branch office
connectivity without configuring gateway on the interface. I will manually
add route on the VM. I have tried all the possibility ways with my poor
knowledge on the CS I could not able to add guest network without
mentioning IP range on the UI also cloudmonkey. I want to configure IPs on
the eth1 nic (Branch network) manually without getting IPs from DHCP, could
someone please guide me on this. We are already running similar setup on
VMware I hope this can be done on cloudstack as well.

Configuration details.

Management Server / computing server is running on Ubuntu detail are below.

Distributor ID: Ubuntu

Description: Ubuntu 12.04.5 LTS

Release: 12.04

Codename: precise

Virtualization is on = KVM

Guest VM OS = Windows -7, CentOS

I have attached detailed diagram for your better understanding, please help
me to configure my scenario.

Thanks in Advance.

Hi, if you don't want DHCP for your branch office network you need to
create a Network Offering without DHCP and select that offering when
adding the network in CloudStack. You may still be required to input an
IP range when creating the network, but CloudStack won't be able to
assign the IPs with DHCP disabled.

Best regards,
Kirk

Hi Kirk

Thanks for your response
I have tried creating service offering without dhcp but while creating
guest network its forcing me to mention IP range. My requirement is that i
will get only 1 IP from each branch network that I have to configure in
guest VM directly. In the branch network switch is created with multiple L2
vlans. Please guide me how to setup this network.

I hope you have seen my model network diagram which i have uploaded in
google drive.

Thx in advance
AR.

Hi, as I said before you may still be required to input an IP range when
creating the network, but it won't be used if DHCP is disabled for the
network. So just input any IP range when creating the network and then
configure the desired IP address in the VM.

Hi Kirk

Thanks for your reply,

adding to some more points on the same case I want to add additional
physical NIC to VM without mention IPs and service offering from cloudstack
is that possible ?. in my case I have 1 VM which has public NIC and need
one more additional physical NIC for internal use. on the WAN side every
thing is working as expected in the same VM I would need to add one more
physical NIC which I need to manually configure IPs in different range
apart from the default CIDR.(Eg - connecting to different network over
MPLS) meaning one guest VM will have two network one towards to public with
default CIDR and other network towards to MPLS on different IP range, is
that possible if so could you please assist me on this.

Thanks
AR
