vSphere work on graphical host?

Is it possible to work directly on the vSphere server and start your virtual machines (eg. windows) there instead remotely?
 
Maybe someone knows a trick I don't, but the short answer is no.

Is there a reason you can't just use the client on a PC?
 
If you use XEN for example, you can just start you operating system on the dom0 machine. So I thought there would also be something to do the same on vSphere.

The reason would be: no client available :D
 
So you want to put ESX on a machine, and then use a VM on that same physical machine?Definitely nothing that I'm aware of, but I'm more than willing to be wrong.

ESXi installs a very basic text based DCUI on the host machine, there is no client interface comparable to vSphere client available on that machine directly.

If you want to interact with a VM graphically (or do anything more than installing ESXi...) you will need two machines.
 
So what happens when you select exclusive rights on the graphics adapter for a single virtual machine. Won't the output be displayed on the host if I plug in a monitor?
 
Are you trying to pass a certain video card to a virtual machine?

Normally you would use the vSphere client to view a virtual machine.

That person is sitting at a PC, using the vSphere client to view a virtual machine that is running on the host (running ESXi).

Does that make sense?
 
Hi Adam12176,

you got me a bit wrong here. Nevertheless, I appreciate your help. Imagine I only have a single computer and want to install the virtualization server and also run the vm clients from/on this server.

As far as I know, XEN does offer this. So you can just start you virtual machine on the command line of the dom0. If vSphere does not support this directly. I thought it might be possible to enable exclusive rights of the gpu to a vm and then plug a monitor to the host and see the output.

Anything like this possible on vSphere?
 
I understand what you're saying, but what you are trying to accomplish - at least to the best of my knowledge, simply isn't possible.

I asked if you were trying to pass through a specific video card for a reason. If so, I know VMWare workstation offers limited 3D acceleration. Your original idea of trying to do this with ESX probably isn't going to fly.

You need two machines to manage/view ESX clients.
 
Well, in a sort of round a bout way you can somewhat accomplish this. However, it's hardly a supported or even viable method for a large number of reasons, and is still very hit or miss depending on hardware. And furthermore, you still really need a secondary system for initial setup and for recovery - thus, if you didn't have another system available for even mildly occasional use, you can end up in trouble.

In any case, if you were to successfully pass through a pcie VGA card (it can be the sole VGA on the system) to a Windows guest, along with a USB controller for I/O (kb/mouse), you can set the windows vm to boot on startup, so it'll come up when you boot up the host. Having vsphere on the guest will then let you do all the administration like any other vsphere instance. Yes, I have had this working personally, so it is possible.

The obvious problem is (not counting the somewhat pain it is to find hardware that does VGA passthrough successfully) that if the windows guest crashes or shuts down for any reason, you're not able to restart it without having a secondary access method.

Bottomline - If you need single system vm hosting, xen is probably a great option as somewhat already mentioned. The above method is more a convenience I could see in very niche cases, and I wouldn't recommend it as a real solution to your issue; rather, it exists. (And let me once more say that getting the VGA passthrough to work to even make this a discussion is much more the exception than the rule.)
