Can’t Remove vApp in vCloud Director (vCD) – Pending State

Deleting a vApp or VM in vCloud director fails because of an invalid state. The vCloud Director still thinks the vApp is still partially running but it can not be stopped.

What does vCloud Director look at when authenticating certificates?

VMware vCloud Director does not care what you specify within the certificates. Instead, vCloud Director only cares that there are the proper number in the user-supplied keystore, that the type of the keystore is JCEKS, and that there is an unbroken trust chain for the certificates.

It is the end-clients accessing the service that will care if the CN or SAN is incorrect for the given deployment, e.g. mismatched CN and FQDN/IP, FQDN not covered by a wildcard certificate, expired certificate, etc. vCloud Director will not refuse to service a request if you make any of these types of mistakes, but the users' browsers or HTTP clients will likely throw up errors or refuse to connect if the certificates are invalid.

vCloud Director and multiple URLs for the Portal

Out of the box, vCloud Director has two URLs—one for HTTP traffic and one for the console proxy. If you want to configure multiple URLs for the HTTP traffic, you will need to set up a load balancer in front of the vCD cells and forward the URLs to the vCD cells appropriately.

The cells will NOT examine the hostname/FQDN for the requests and will not be able to distinguish a difference between myhpc and mycloud requests. As far as they are concerned, if they receive the request they will attempt to satisfy it if the resource exists.

vCloud Director Fast Provisioning condsiderations

The number of datastores affects manageability, and therefore the fewer datastores involved the better. In terms of fast provisioning, IOPs are a better metric to watch and using caching for the type of use (read caches for VMs that do a lot of lookup, write caches for VMs that write a lot) are larger benefits.

Factors to consider that affect performance include:
- total number of VMs on volume
- IOPS capability of volume (underlying disk aggregate)
- fast provisioning enabled
- thin provisioning enabled
- rate of power operations on VMs
- rate of cloning operations,
- cache size and balance (rea d/write)
- level of VAAI integration
- number of connected hosts.
