Hi,

You can use vlan as tenant network too. But You have to remember that vlan is 
provider network, which means that You need to have configured vlans on Your 
network infrastructure too. And in case of tenant network, Neutron will 
automatically allocate one of the vlan ids to the network as user don't have 
possibility to choose vlan id for network (at least that's default policy in 
Neutron).
So, You should check what vlan id is used by such tenant network, check if 
this vlan is properly confiugred on Your switches and then, if all is good, 
check where exactly such dhcp requests are dropped (are they going from 
compute node? are packets comming to the node with dhcp agent?). Base on that 
You can narrow down where the issue can be.
