In my organization, we moved to ubuntu from Windows , We are using Vmware esxi 5 as our virtual platform.
There is no client tool available to access Vmware esxi in Linux.
How can I access Vmware esxi 5 from ubuntu 12.04 ?
If you are using vCenter then you can use the Web Client to administer vSphere hosts.
If not then you can try running the vSphere Client in Wine on Ubuntu.
See previous discussion here: Access Vmware Esxi from Ubuntu 12.04.1
Hope that this helps.
