Normally you would enter your Virtual Center server host name when logging in with the Virtual Machine MKS Client. But in some circumstances it may be necessary to logon to your ESX server directly. Bypassing the Virtual Center is never a good idea because you can make your cluster instable, but on the other hand if you don’t have a Virtual Center Server anymore and still want to use the Virtual Machine MKS Client you received an error. Until now, with version 1.8 you can both logon to your VC server and directly to your ESX host. Keep in mind that when you logon to the ESX server directly you have to use the service console Linux account instead of your Windows account.
