[Openstack] [xenserver-ocata] neutron-dhcp/metadata agent on XenServer

As the link https://docs.openstack.org/ocata/networking-guide/config-dhcp-ha.html described, we can add DHCP agent in compute node (DomU) and it make sense as VMs just get internal fixed IP, so locating the DHCP in compute node should work.
If the VM cannot get IP, I suspect maybe the VM’s DHCP request isn’t arrived to that DHCP agent, maybe the so here are some questions:
1. The agent_scheduler isn’t work for the DHCP agent in Nova compute node? Could you give some logs of DHCP agent.
2. The VM isn’t get correct internal vlan tag? Could you double check about the VM’s VIF information in Dom0.
a. ovs-vsctl show
b. ovs-ofctl show br-int
c. ovs-ofctl dump-flows br-int

yep, yesterday I try to install neutron-dhcp/metadata agent along with nova-compute inside of compute node (domU) , the neutron-dhcp/metadata agent was working, I see from the log. but instance can't get the IP address from dhcp server.
the working scenario now, I made 2 network node, on each network node contain L3-Agent, DHCP-agent, and metadata-agent.

If the Neutron agents would normally run with the nova compute services, then they would need to run in the compute VM when deploying with XenServer, not in domain 0.
I would assume that the DHCP agents should also run in the compute VM.
Also added openstack at citrix.com<mailto:openstack at citrix.com> to include others.

According to this guide:
If I want to add HA on my openstack-xenserver environment , is it possible to include neutron-dhcp/metadata agent on Compute-node ?
or I have to add neutron-dhcp/metadata agent on xenserver dom0 ?
or I have to create more neutron-dhcp/metadata agent on separate node ?
