Re: [one-users] OVH (So You Start) + OpenNebula + 1 IP
Hi all, first of all, thanks for your assistance. Finally I have bought 8 ip's to have a easier network set up.I did not find how to automatize the creation ov vms with NAT network and port redirections. In relation with the problem with OVH and the connection lost when you attach a bridge to an interface, it is fixed. The problem was the next: reading this http://docs.opennebula.org/4.6/design_and_installation/quick_starts/qs_ubuntu_kvm.html#configure-the-network I supposed I should leave the eth0 definition without change it. I mean, I would have to add the br0 definition below the eth0 definition. I did not realised that the /etc/network/interfaces must have only defined lo and br0 (attached to eth0) as it is documented. Having br0 with the main IP and lo is how the interfaces should be set up. So if you have the same problem, put the same network configuration than the documented one. Cheers, Pablo Hinojosa.

I've done it in the past (not for OpenNebula, but for XEN VMs running inside an OVH server) and the problem is the MAC filtering, as Valentin says. You have to add new MACs from your control panel, and use Failover IPs (not sure if this is mandatory, i was using these Failover IPs to give public access to my VMs) .

You can choose to use Linux bridge or OpenvSwitch. Either of the two are really easy to set up and running. OpenNebula has network drivers for both of them. I would choose OpenvSwitch :).

[one-users] OVH (So You Start) + OpenNebula + 1 IP
Hi all, I am having problems trying to set up an OpenNebula host to virtualize with KVM. I have bought a dedicated server with OVH (So You Start) with 1 publlc IP. The public IP is on eth0 interface and each time I try to create a Linux bridge (as is suggested during the installation http://docs.opennebula.org/4.6/design_and_installation/quick_starts/qs_ubuntu_kvm.html#configure-the-network ) I got frozen the SSH connection. If I edit the file /etc/network/interfaces, then I run /etc/init.d/networking restart and it seems the server does not do anything. If I restart the server with changes made, I cannot recover the connection and I have to reinstall the operating system. If I try to create the bridge by hand, I the same problem (connection lost) when I try to add the bridge to the public network interface (etc0). It seems OVH use Mac Filtering switches, so that could be the reason. I could buy a block of 8 or 16 IPs, but it does not change way to configure OpenNebula. Should I use NAT? should I use virbr0? Does anybody have experience with OVH? Do you know what is happening? By the way, I have phoned OVH support and they told me Ubuntu is not to virtualize. Cheers, Pablo Hinojosa.
