Hello,

I installed RancherOS on **windows/virtualbox** and it works.

The installation was quite simple.

I had to define 2 NIC, when one was a **NAT host only adapter**.

Through the host only adapter, I could connect in SSH (puTTY)  
and create/edit the cloud-config.yml (especially paste the SSH key)

Now, I’d like to install RancherOS on **CentOS7/KVM**.

I didn’t succeed to define a NAT host only adapter, so I have  
only one NIC and I defined it as bridge adapter.

I connected to RancherOS through the KVM console, and I set (in  
the live Rancher) a static IP

under **/etc/network/interfaces**  
, I added what is necessary for my network (we have fixed IPs)

> auto  
> eth0

> iface  
> eth0 inet static

> address 10.0.98.98

> gateway 10.0.0.254

> netmask 255.255.0.0

And I restarted the service

(I tried the both)

> sudo system-docker restart network  
> sudo ros service restart network

But nothing.

No connection and no IP under ifconfig/eth0

So I cannot connect with SSH (puTTY) and I cannot complete  
the installation (paste the SSH key)

So…

Is it possible to set a static IP before the installation,  
and if yes, how?

Or do I have to install without SSH key and add it after?

Or any other solution.

What is the right way in my case?

Thanks,

Sam.

RancherOS networking isn’t configured via `/etc/network/interfaces`. Please check out our docs on configuring interfaces ([http://docs.rancher.com/os/networking/interfaces/](http://docs.rancher.com/os/networking/interfaces/)).
