I don't know how the View Time Table plays into things, I've never looked at 
that before, mine is currently blank.

Unless I'm not understanding the setup, you have to have as many computers 
defined as you want to have instances of your image running. For each computer 
you define you assign a unique mac address. To make a reservation for the 
image, there has to be an available computer for the reservation to run on. If 
you want to have 10 concurrent reservations, you have to have 10 computers 
available.

The image also must be assigned to an image group, and that image group has to 
be mapped to a computer group which contains the computers the image can run 
on. There is good explanation of this at the Documentation link on the VCL home 
page.

Hi Mike, List,

Apparently, my understanding is still a bit off.

Since I've captured the image successfully "No Apps (Linux)", name:
vmwarelinux-base10-v1, with the appropriate files copied over to
$DATASTORE/golden/vmwarelinux-base10-v1/

I'm thinking that I'll be able to spawn as many "instance" of the "No
Apps (Linux)" as I configure the ESXi to handle.
That was the idea behind capturing an image right ?  How would I be
able to achieve that ?

I create another computer called "vm-tospawn", populate the mac
addresses field and assign it to my only ESXi host.
Nothing shows up on the "View Time Table". What are the fields that
say "vm-tospawn" is associated with the "No Apps (Linux)" image I
captured ? If I populate the mac address fields, if I spawn 2 version
of it, wouldn't I cause conflicts on the Mac address ?

I still need some guidance on how to go from successful image capture
to launch multiple of them on ESXi host.

What am I missing ?

Thanks
