Recently I implemented ESX 3.5 with VirtualCenter 2.5. After I installed the ESX Hosts and the VirtualCenter server the customer told me that I had to change the ip-addresses of the service console. I removed the ESX hosts from the VirtualCenter server, removed the vswif of both hosts with “esxcfg-vswif -d” and created it again with the correct ip-address and subnet. I added both hosts to the cluster again and every thing seemed to work again… until I decided to rollout a template. It took over 10 minutes before the error “failed to connect to host” appeared.

When looking for the “maximum number of allowed console connections, I stumbled upon another handy option in VirtualCenter, “Edit -> Client Settings”.
- Set the maximum number of allowed console connections (0 to 100) to all virtual machines.
- Close all “Getting Started” tabs at once.
