[one-users] VM networking configuration CentOS

[Mark Kusch]

Hi list,

I've a vnet defining IP and MAC address fields (required).
I've a working bridge configuration which should grant accecss to a
corporate DHCP server configured for exactly these IP/MAC pairs.
I've a CentOS qcow2 image with eth0 configuration set to DHCP.

When instantiating a VM it comes up with eth0 configured with IP
0.192.222.10/24. MAC address is configured correctly from the vnet.

onevm show $ID lists expected networking configuration.

Any hint why the VMs come up with such an IP address? Could that be
OpenNebula related? Or does this feel to you like CentOS related?

In HOPE anyone has seen such an issue and can point me somewhere
which explains it to me and hopefully results in a solution ;)

Thanks!
