Menu item ‘Edge Gateway Services’ grayed out in vCD

Some time ago we had problems with the NSX Manager, had to deploy a new Manager appliance and restore a config backup. However, we were unable to manage Edge Gateways in the vCloud Director web interface after this work. Neither as Org Admin, nor as System Admins. In the Action menu the item “Edge Gateway Services” for configuring the network services was simply grayed out. Even a Re-deploy of the Edge Gateways didn’t help.

Get root access to all NSX components

The topics “How do I get root access to the different NSX components” or “How can I find the root password” comes up quite often. For some components it’s already widely documented (for example NSX Manager) and for other components it’s rarely described (for example the NSX controllers). I also haven’t yet found a complete overview of how to get root access to the underlying Linux layer on all components. So I thought I’d put this information together here for the NSX versions 6.3 and 6.4.

Distributed Switch Healthcheck and the error “VLAN 0 is not supported”

Since upgrading to NSX 6.4, I get warnings for certain ESXi hosts because there is a VLAN and MTU mismatch. So I checked the vDS healthchecks and found the following error: VLAN 0 is not supported. But since we didn’t remove or add VLANs on the physical switches, I was very surprised. And VLAN 0 shouldn’t exist anyway. So, what is it about and why does the error suddenly occur?

Internal server error while accessing NSX Logical Switches

We have recently upgraded from NSX-v 6.3.3 to NSX-v 6.4.3. The upgrade went well so far, but after the upgrade we noticed that the list of logical switches was no longer loaded correctly.

Depending on how we sorted the list, the list was either empty and the error message “Internal server error has occurred” was displayed or it happened while scrolling. In any case we couldn’t use the list with the logical switches anymore. And unfortunately the error message is quite useless.

So we went through the logs of the NSX Manager and found what we were looking for in the vsm.log.

vCloud Director 9 load balancing with NSX edge gateway

For high availability and performance reasons, it makes sense to run multiple vCloud Director cells. To do this, you can place a load balancer in front of it. And since we already use NSX for vCloud Director 9, it makes even more sense to use an edge gateway for load balancing.

However, there are a few pitfalls, for example with terminating HTTP connections, session persistence and especially with the VM Remote Console via the browser.

In my blog post I show you how to configure NSX and vCloud Director 9 and what to consider for this setup.
