Hi Stefan,<div><br></div><div>My guess is that if you're using a preexisting image, udev will have already created a persistent rule associated to your old NIC device labeled as 'eth0'. If you deploy it with OpenNebula, the MAC address will change (most probably) so the new network interface will be labeled 'eth1'. If I'm not wrong and that's the problem, try removing that persistent 'eth0' udev rule.</div>
<div><br></div><div><div>Anyhow, the best way to find out what's going on with your VM is to enable VNC access to it. You can then connect to the VM and see what's going on.</div><div><br></div><div>To do that try using this in your VM template, for instance:</div>
<div><div><br></div><div>GRAPHICS = [ </div><div> type = "vnc", </div><div> listen = "127.0.0.1",</div><div> port = "5"]</div></div><div><br></div><div>for more info check: <a href="http://opennebula.org/doku.php?id=documentation:rel1.4:template#i_o_devices_section">http://opennebula.org/doku.php?id=documentation:rel1.4:template#i_o_devices_section</a></div>
<div><br></div><div>And one more thing, you don't need to pre-configure the network settings (IP, etc), you can do it dynamically by using vmcontext: <a href="http://opennebula.org/doku.php?id=documentation:rel1.4:vgg#using_the_leases_within_the_virtual_machine">http://opennebula.org/doku.php?id=documentation:rel1.4:vgg#using_the_leases_within_the_virtual_machine</a></div>

<br>
I'm pretty new to OpenNebula. I compiled, installed, and configured it<br>
in Version 1.4 (using KVM) on two Ubuntu 9.10 Servers. My cluster node<br>
has a network bridge br0 and the ttylinux example works fine.<br>
<br>
But now I wanted to deploy a self created VM so I created one with the<br>
Virtual Machine Manager on my workstation. I used Ubuntu 9.10 server<br>
64bit for that, configured the /etc/network/interfaces of the VM with<br>
the right IP, installed sshd, and copied the image to the server who is<br>
the cloud manager. onevm create vm1 works, VM status after a while is<br>
runn.<br>
<br>
But unlike the ttylinux my VM is not pingable or reachable via ssh.<br>
<br>
Did I miss something to configure? Or any other mistakes?<br>
<br>
My templates look like this:<br>
<br>
<a href="http://small_network.net" target="_blank">small_network.net</a>:<br>
------------------<br>
NAME = "Small network"<br>
TYPE = FIXED<br>
<br>
#Now we'll use the cluster private network (physical)<br>
BRIDGE = br0<br>
LEASES = [ IP="xxx.xxx.xxx.204"]<br>
<br>
vm1.one:<br>
--------<br>
#---------------------------------------<br>
# VM definition example<br>
#---------------------------------------<br>
<br>
NAME = vm1<br>
<br>
CPU = 1<br>
MEMORY = 512<br>
<br>
# --- kernel & boot device ---<br>
<br>
OS = [<br>
kernel = "/vmlinuz",<br>
initrd = "/initrd.img",<br>
root = "sda" ]<br>
<br>
# --- 2 disks ---<br>
<br>
DISK = [<br>
source = "/srv/cloud/temp/vm1.img",<br>
target = "sda",<br>
readonly = "no" ]<br>
<br>
DISK = [<br>
type = swap,<br>
size = 1024,<br>
target = "sdb",<br>
readonly = "no" ]<br>
<br>
# --- 1 NIC ---<br>
<br>
NIC = [ NETWORK = "Small network" ]<br>
<br>
<br>
Best regards<br>
<br>
Stefan<br>
