Fwd: Cloud Stack dhcp issue
Hi all,
I have cloud stack configured and working fine with default virtual router.
In my case i have a VLAN where physical DHCP and DNS server are running.
If i will create virtual router with dhcp ans dns service enabled dhcp may
conflict, So I have created NETWORK OFFERING with only connectivity and a
guest network with some specified ip range, so it won't create virtual
router and guest VM will be assigned IP from physical DHCP server. but what
I observed is guest VM has received one IP which is not the same IP which
is shown in INSTANCE DETAIL.
Even I confirm in mysql database in "nics" table, guest VM ip which
assigned from physical DHCP server is not updated.
Please guide me what I am missing here.
Thanks.
Tejas

Hi tejas follow following steps
1.Create a network offering without any service ,just select connectivity.
2.Enable that service offering.
3.Create a guest network in which already a dhcp server is running with
above network offering.
4.Created an instance with above guest network.
5.The Cloudstack assigned ip from given pool to guest network.
6.But the instance will get different ip from dhcp
7.Change the database entry for newly created instance in vm_instance table
,change the private_ip_address entry to new ip.
8.Find the mac of newly created vm .
9.In database go to nics table and change the ip4_address for the mac of
the instance.
10.Finally the change will reflected in cloudstack.
Try to automate the above task.
Thanks

Hi,
Configure your physical dhcp server to serve IP1 to VM1.
>From the cloudstack deploy vm VM1, specify the IP1 to use for the VM (in API).

Hi Kirk,
Thanks for quick replay,
I have physical DHCP and DNS server running and I want to assign IP to
guest VM's from physical DHCP server.
So what should I do.
Thanks,
Tejas

Re: Fwd: Cloud Stack dhcp issue

Hi, if you configure a CloudStack network without DHCP or completely
without a virtual router, CloudStack cannot configure networking for the
VM. You will need to configure networking in the VM. If you have your
own (non-CloudStack) DHCP server for the network, you should configure
it to assign the desired IP settings to the VM. Or you can manually
configure a static IP in the VM.
Best regards,
Kirk
