[one-users] eth0 not detecting guest Centt OS VM in opennebula

[Lauro Israel Balderas]

What's in your /etc/sysconfig/network-scripts/ifcg-eth0???

In my case ifconfig didn't return eth0, this was because BOOTPROTO was set to dhcp, however I didn't have a dchp server on that vlan. In my contextualization script I set BOOTPROTO to none & I set the IP based on the mac address (docos availables on the open-nebula website) After rebooting & saving the VM as a new image everything seems to be working

Hello,

can you send us a few things:
- brctl show (in the hypervisor)
- network template
- virtual machine template

Also, please include the GRAPHICS section in your template, so you can have VNC and debug the network issues from there:

cheers,
Jaime

The VM successfully getting started but there is no ethernet (eth0) connection.
