Testing Guest network
Hi,
We currently have CloudStack 4.8 installed on 12 CentOS 7.2 servers.
1 of these servers is being used as the management server.
We have been able to get the SSVM, CPVM and VR up and running, however,
when a VM is created it does not have access to the given gateway (VR).
Is there a way to test that the guest network is sending packets
correctly across the network?
I have manually created a VLAN on each server to ensure VLANs are
working on the network, though I am unsure of whether or not the CS
created VLAN interfaces are working correctly.
Any advice would be great and let me know if you need further information.
Regards,
Enzo

Hi,
In case someone else has the same or similar issue.
We found (with Glenn's assistance) that the bridge interface for the
guest network was not being brought up automatically.
We are waiting for more information as to why this is happening.
Regards,
Enzo

Hi Enzo,
To isolates if there is any problem with VLANs, you can migrate guest vm and VR to same host and check the gateway(VR) reachability from guest vm.

Hi Enzo,
I guess from your post you are using KVM on your hypervisor hosts? If so which bridge backend are you using - linux bridge or OpenVswitch?

Hi Enzo,
As Sanjeev said , try move the Guest VM's to the same KVM you have running the VR on.
Then if that works , check that you have setup your guest Vlan range on the Dell Switch.
Thanks
Glenn
