Here, the vlan mode is implemented in the virtual machine openstack, and it is eager to realize the solution of the communication between the cloud virtual machine generated by the openstack platform and the (wmware virtual machine) and the physical machine. There may also be an easier way to welcome everyone to communicate.

openstack platform network environment

I was lazy when I created it here. I used 1 for the segment ID. Of course, you can define other segment IDs yourself, but the corresponding virtual network card segment ID needs to be changed.
Network type: vlan
physical network: provider
Segment ID: 1
Subnet gateway: 192.168. 200.2 Same as Wmware virtual network card

Note: The next step is very important, which is to turn on the vlan ID of the VMnet8 network card. This is consistent with the vlan segment ID created by the openstack platform. Here I write 1

Platform routing

Create a cloud host here, the floating ip is 192.168.200.8

Virtual machine environment

Here the control node and the computing node are three network cards
ens32 192.168.100.0/24 gateway 192.168.100.1 host only (VMnet1)
ens33 192.168.200.0/24 gateway 192.168.200.2 nat mode (VMnet8)
ens35 192.168.10.0/24 gateway 192.168. 10.1
Description of host only (VMnet2) : Why three network cards are used here, because when ensp is started later, he will preempt ens32 and ens33, causing tools such as CRT to fail to connect to the virtual machine and the cloud through these two (virtual network cards VMnet1, VMnet8) network cards The host, so it depends on the third network card ens35 to achieve.

ensp environment

By the way, there can actually be simpler topologies (methods), but I only think of this one at the moment. If you have a simpler method, you can communicate with me.

Test connectivity

Switch LSW3 can ping VMnet8 network card and openstack platform virtual machine

Switch LSW2 can ping VMnet1 network card and WMware virtual machine

Use CRT to connect to the third network card to test

Due to the preemption of the network card, the CRT cannot connect to the openstack cloud virtual machine and the control node of the 192.168.100.0 network segment, so we can use the third network card to enter the cloud virtual machine or control node through ssh. Here we can also see With the help of ensp, our cloud virtual machine can also communicate with control nodes and computing nodes.

Do some configuration of ansible, you can use ansible normally.
