Running ESX.Next under Workstation 6.5.1 is supported. A few weeks ago I filled a support request, because I couldn’t start a virtual machine on ESX.Next while ESX.Next was hosted on Workstation 6.5.0. ESX.Next kept crashing at 95% during the VM Power On. An anonymous source just brought me up-to-date and whispered the following:
The WS 6.5 bug you noted earlier has been fixed. You will be able to run nested VMs under ESX.Next under WS 6.5.1, subject to the usual caveats (hardware virtualization has to be supported on your host for running the outer guest, and the inner guest is restricted to 32-bits).
What's New:
With this release of VMware Workstation, the following new features and support have been added:
Japanese localization — A localized version of Workstation is now available in Japanese for Windows hosts.
Smart card support for Linux guests — Smart cards are now experimentally supported with Linux guests.
Unity mode on Linux guests — Although support for Unity mode on Linux guests is still experimental, repainting of application windows is much improved.
3-D graphics — Additional improvements have been made to improve 3-D performance on Windows XP guests.
