I installed VMWare Server 2 in a Centos 5.2 virtual machine which runs in a VMWare ESXi Server. When I try to start, via browser, a VM I created in VMWare Server, it gives me the following message: "You may not power on a virtual machine in a virtual machine.". Is there a way to put the VM to work?

    Is there a particular reason why you are trying to run a VM inside of a VM? – TimK Dec 2 '09 at 16:15

    That's by design. Is there something that you specifically need VMWare Server for when you already have an ESXi system? – ewwhite Dec 2 '09 at 17:04
  • Starting a land-war in Asia
  • Inventing the hoola-hoop
  • Trying to VM inside a VM

All bad ideas

  • +1 for the land-war in Asia. But you forgot: "Never go against a Sicilian when death is on the line". :) – osij2is Dec 2 '09 at 17:30
  • There is nothing wrong with starting a VM inside a VM, in fact, VMware now directly supports this feature. – Brennan Apr 16 '10 at 18:34

    Just because something works and is supported does not make it a good idea, have you tried it? did it work in a way you'd be happy to support in production? well I, and a number of other SF'er and others outside SF have - and we agree that it's a bad idea. – Chopper3 Apr 16 '10 at 19:19

You may want to see this. It may not work with VMware Server, but if it works with ESX/ESXi, it probably will.


Why not use VMware Converter (free standalone) to convert the VM to ESX format and save yourself some machine power by not doing VM-inside-VM?

  • Because my concern is not about weight on the server, but in the clients, which are old desktops with serious processment restrictions, unable to run the heavy-load VMWare ESXi client (vSphere), but perfectly able to run the VMWare Server 2 browser client. But instead of going on trying this experimental "nested virtualizaion", I'm thinking about simply substitute VMWare ESXi by VMWare Server. – CHUCO Dec 3 '09 at 18:52
  • In this case you may want to look at VMware View. Kinda like Terminal Services, but with VMs. – Rafael Fonseca Feb 16 '10 at 0:30

VMware Workstation now supports this feature, you can run ESXi via Workstation.
