<div dir="ltr">Hi all,<div><br></div><div>I have a OpenStack controller + Neutron hosted in a VM provisioned by VirtualBox. In another physical server I have my compute node. I configured Neutron to use VLAN tenant network and trunked the 2 ports of the switch connecting the compute node & the host of the controller. However when I create instance on the compute node, I found that my instances failed to talk to the DHCP server in the same tenant network. It is revealed that those DHCP packets from the VM has its VLAN tag in place when arriving the host machine. However, when they entered VirtualBox, the VLAN tag of the packet is stripped and thus making neutron to fail routing the packet to the proper tanent network.</div>
<div><br></div><div>From Google I found that there are many workarounds (i.e. using Virtio instead of Intel for VNIC, etc), but so far none of them work for me. So may I know if any of you have experience using VirtualBox to host controller and successfully used VLAN tanent networks? If so could you kindly share your config (i.e. the type of VNIC you used for VirtualBox) with me?</div>
<div><br></div><div>Thanks a lot.</div><div><br></div><div>Regards,</div><div>Tim</div></div>
