Installing vShield Manager and vShield app service to the same ESXi host

[dbutch1976]

Hello, I am planning on evaluating vCloud director in a lab with only a single ESXi host.  When I attempt to install the vShield app service I get the following warning: Do not install on a host or cluster where the VC or vShield Manager reside. This can cause network disruptions. The IP address below should be a unique IP address allotted to this vShield App appliance. Please do not use an IP address assigned to some other machine including VC, vShield Manager or any ESX host. Using an incorrect IP address will require you to uninstall and re-install vShield App on this host. My question is: Is it is absolutely impossible to install vShield manager on the same ESXi host as the vShield Manager resides?  Or is this just bad practice?  What are the ramifications of proceeding with the install?

It is a commonly followed practice to segregate the management and resource infrastructure. What you see is just a warning. When there are very less resources available you can do it. Make sure you exclude the required VM's by refering to this post
