The first time I tried to access the VMWare ESX 4 web client, I got this 503 Service unavailable error, which made me think I broke something. But on the second install, I got the exact same message.
While this is not important for most Windows users, as a Linux user I need this entry as there is no vSphere client for Linux.
In a default installation VMWare ESX 4.0 appears not to be running all required daemons to connect to the web client.
So what to do?
Log on to the server over SSH (console access)
Type service vmware-webAccess status to check the current status of the webAccess daemon
Type service vmware-webAccess start to start the webAccess daemon
run /sbin/chkconfig –level 345 vmware-webAccess on to make webAccess start automatically on booting the ESX server
Make sure to firewall the ESX management to prevent abuse.
