[one-users] external DHCP

[Andreas Calvo]

Hello,
We're building a VM farm with OpenNebula.
However, I'm a little bit confused about how to handle networking.
Our scenario is based on VLAN tagging and external DHCP server for every
VLAN.
Our goal is to use that external DHCP server to provide IPs for all VMs.
When creating a Virtual Network, a mandatory parameter is the range or
fixed address (otherwise it fails complaining it cannot allocate the VM
Network).
We've tried Open vSwitch (without luck -- fails to create the vm
directory) and 802.1Q (needs an explicit range/fixed address to
instantiate a template).

Is it possible to use a external DHCP server?
Is there any issue using any VLAN tagging service (802.1Q or Open
vSwitch)?

Thanks!
