Unfortunately, I made a rookie mistake - I didn't understand that in the virtual-network template I need to set the bridge that was created on the CLUSTER-NODES!!! All I had to do now is find out the correct name of the libvirt-created bridge (virbr0) and now the VM's are finally running :)</span></div><div><br><span></span></div><div><span>Thanks a bunch for your help!</span></div><div><br></div><div style="font-family: times new roman, new york, times, serif; font-size: 12pt;"><div style="font-family: times new roman, new york, times, serif; font-size: 12pt;"><font face="Arial" size="2"><hr size="1"><b><span style="font-weight:bold;">Von:</span></b> Jaime Melis <jmelis@opennebula.org><br><b><span style="font-weight: bold;">An:</span></b> Adnan Pasic

I'll<br>assume you want to connect your VMs to the same network your eth0 is<br>connected to. The following commands should be executed on the worker<br>nodes.<br><br>brctl addbr br0<br>ifconfig eth0 0.0.0.0 up<br>brctl addif br0 eth0<br>ifconfig br0 <old_eth0_ip_address><br><br>Don't do this over an ssh connection since you will get disconnected.<br><br>That's quick recipe to make it work, but you should read documents on<br>bridging, especially to make the persistent, each distro has its own<br>mechanism:<br><a

two clusters (with IP-addresses: 192.168.0.1 ,<br>> and .2, .3 respectively) and now everything is set. Even the command<br>> "onehost list" shows me the clusters as being discovered and connected.<br>> Currently I have only two interfaces in my front-end, eth0 (connecting the<br>> PCs over a local network) and the lo-interface.<br>> Can you now please tell me how I can create this virtual bridge, needed for<br>> our virtual machines?
