There's at least the possibility to configure with which vlan to start, config
file located in "../one/remotes/vnm/OpenNebulaNetwork.conf"

################################################################################
# General Options

# Configure the initial VLAN ID tag (corresponds to vnet ID = 0)
:start_vlan: 2

I just configure the VLAN_ID's in the vnet template (VLAN = "YES",
VLAN_ID = "VID") so you have control over which VLAN gets used.

p.s. Don't forget to run "onehost sync --force" to update host configs
