Re: moving my virtual machines from vmware workstation to vmware vsphere

Well there is one more option but it requires a special quite expensive videocard.
ESXi allows to pass a small list of enterprise class hardware to be passed through to the guests.
I dont remember which videocards are on this list but if you have one of these cards you can setup a ESXi host that actually really allows to use the same host as a Workstation.
So you would start ESXi and then start a Windows VM with the physical video card in passthru mode via commandline.
Once the VM is up it will use the monitor to display its desktop in 32bit colour with a good / modern resolution.
