New VMware KB Article – Cannot not add ESXi Host

MikeLaverick MikeLaverick Profile: MikeLaverick

This new KB article caught my eye from VMware today… At first I thought it might be an answer to my disconnects to ESXi when was doing the upgrade to vSphere 4.0 Update 1. It’s entitled:

“Adding an ESXi 4.0 host to vCenter Server 4.0 fails with the error: Cannot install the vCenter agent service. Unknown installer error.”


My favorite bit was the part on how to resolve this problem – which stems from lack of memory on the ESXi host:

This issue can occur if the ESXi host is low on RAM. The host can be low on RAM either because it does not have enough physical memory allocated to it, or because too many virtual machines are consuming RAM at the same time.

If the host does not have enough physical memory allocated to it, you can allocate more physical RAM:

1. Power off the virtual machines on the host.
2. Power off the ESXi host.
3. Allocate more physical RAM to the host.
4. Reboot the ESXi host.

Priceless, huh. I literally laughed out loud when I read it. Especially the step by step instructions! :-)
