Hi Adhi, Welcome, no need to add physical port to br-int. We just want to check the DHCP request can be received by DHCP agent. We met such issue that VM cannot get IP via DHCP, see my blog https://www.citrix.com/blogs/2015/10/13/xenserver-debugging-on-vmscannot-get-ip-from-dhcp-agent/ (seems there are some format issues ,so you can refer this https://github.com/Annie-XIE/summary-os/blob/master/test-blog.md) maybe you can also check these aspects in the blog.

I'll paste the dhcp logs later.

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 Thanks, Huan From: Adhi Priharmanto [mailto:adhi....@gmail.com<mailto:adhi....@gmail.com>] Sent: Wednesday, August 23, 2017 9:32 AM To: Bob Ball Cc: openstack; #OpenStack External Email Subject: Re: [Openstack] [xenserver-ocata] neutron-dhcp/metadata agent on XenServer hi bob, 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.

I would assume that the DHCP agents should also run in the compute VM. Also added openst...@citrix.com<mailto:openst...@citrix.com> to include others.
