Re: [Users] oVirt in PAT - NAT environment

2014-03-11 Thread Jarno Puff
Hi René,

I don´t have a second NIC, only a public on eth0.

So, if I understood correctly, Neutron is not part of oVirt, but needs to be 
installed a part.

I need to use the All-in-one version of oVirt, so I need to install Neutron on 
this same host?

Any additional advice?

Hi Jarno,

It should work in the following way (needs to be tested - had a similar 
setup with plain KVM, but didn't test it with oVirt):
- create a new network in oVirt and bridge it to your second nic (I 
guess the server will have 2 nics) or a dummy/virtual interface
- create your nat rules in iptables (if you're not that familiar with 
iptables you could use FWBuilder or shorewall).

Here's a documentation on how to setup Neutron:

Regards,
René

 Hi Assaf,

 thanks for the answer.

 the data center where my server reside is a server4you.net, so all what you 
 get is a dedicated server and a public IP, thats it. You don´t have a 
 private network via a NIC, the only access to the server is via the public 
 IP.

 Ok, let´s try Neutron. Where can I find details on this? How to enable it and 
 how to configure it?

 Anyone could also give me advices on how to setup the iptables on my server 
 for correct DNAT and port forwarding to VMs? I would like to try boths.

 Hello folks,


 Hi!

 I know, this is a topic where you have spend a lots of words, but, after
 installing oVirt 3.3 and 3.4 on CentOS and let goign google search engine to
 become hot, I don´t found any solution for my environment.

 My environment:

 - dedicated server at server4you.net with CentOS 6
 - Main IP (public) 82.25.xx.yy
 - Addon IP (public) 62.75.xx.yy

 What I will do:

 - create VMs on a private network 192.x.y.z
 - talk to the internet from the VMs (NAT)
 - reach the VMs from the internet (PAT)
 - reach the VMs via SSH from the host server


 oVirt doesn't have built-in support for NAT. What you can do is either:
 1) Define PAT on the data center edge router. For accessing VMS from the 
 outside
 you can either define port forwarding or DNAT. As for reaching the VMs from 
 your
 dedicated server, the easiest approach would be ensuring that the server has
 a leg in the private network.

 2) You might want to try the oVirt Neutron integration. In Neutron you can
 create arbitrary private networks and VMs will get IPs from a DHCP server
 created in Neutron. You can then define a 'floating ip', which is a mapping
 between the VM's private IP and an allocated public IP on your public network.
 Neutron will do the DNAT for you.

 The oVirt Neutron integration in the recent 3.4 release [1] greatly improved
 the integration and it now includes IP address management, so you'll be
 able to do *nearly* everything from the oVirt GUI.

 I found some workarounds, but no one was easy to implement or the infos was
 not cobering all the aspects.

 I have seen the possibility to use a hook, but no user guide and step by
 step instruction found.

 Looking forward to get a working solution :-)

 Cheers,
