I attended the course, just finished it on Friday. Still a bit confused on how Windows is involved. For every VM we create for an app we must associate a guest OS, correct? I am perplexed because Windows is a VM. I understood a lot from the course. Its just the beginning stuff - Windows. Right now I use Windows to do everything. But, are you saying that I no longer use Windows but instead ESXi? If I have 15 VMs, that means all VMs have Windows as their guest OS if I only installed one OS? If I update the OS VM that gets reflected on the guest OS? Do I do a full install of Windows on the VM as if I was doing it on a new box and not using VMware? Regarding the .iso, what do you mean? Do I convert first the Windows cd/dvd into an .iso and place that on the datastore with other .iso files? Do I then create a VM and call it Windows 2008 and point it to the .iso to install? Do I do a normal install as if I was doing it to a new box without VMware? Or is it a different type of install?

Does vCenter server get installed on the Windows VM?
If I have two host does that mean I must have only one Windows VM but two licenses for Windows? does both host share that Windows VM?

ASKER

When I install vCenter server, do I first create a VM and install it on it with a Windoes guest OS?

I need answers to these questions. I am taking the certification exam on Monday, if I don't understand this part I might fail. It is the building block. I understand everything else about VMware, its only this beginning stuff that is perplexing. Once I get the concept down it is simple afterwards to understand it. Please help.

I am wondering if I do an update to the original VM with the Windows OS and if it is good can I pass that updated version to the other VMs since they were from templates or clones?

So, that means I have to update each VMs guest OS manually?

I attended a seminar and they said I apply the update on one and pass it to all. It now sounds like that is not the case. It sounds like I have to clone the OS VM and update that one, if nothing is wrong then I switch the VMs and delete one of the them. Since the update worked on the OS VM and it passed then I could do the update on the rest of the guest OS that is on each VM individually or as a group. I am wondering if I would have to do a restart on that VM if the guest OS requires it.
