Openstack is a virtualization management interface where it supports multiple hypervisors including VMware ESXi and KVM. It is possible to manage both hypervisors under the same Openstack deployment.

Openstack supports provisioning of baremetal machines under a project called Ironic.

VMware Integrated Openstack and Red Hat Openstack can both be managed solutions.

Do a tcpdump on your hypervisor or capture packets from your switch. Filter with your IPs. You should be able to see the traffic whether they are tagged correctly.

2019-06-23 00:27:07 -0500 answered a question openstack with flat VLAN question?
  1. switch trunk port should be connected to your compute nodes
  2. for example, if your compute node is running KVM and openvswitch, on each compute node, each port is VLAN tagged and traffic sent via the physical network interface of the compute node to the trunk-ed port on your L3 switch. you can see the tags using ovs-vsctl show
  3. each instance has a port, VLAN tagged, when you assign a network to it. IP can be assigned by Openstack's neutron DHCP agent when you spin up the instance.
