I have a CPU supporting Intel VT-x, but VMware is refusing to run a 64bit guest operating system ("This host is VT-capable, but VT is disabled."). I think VT is enabled in the BIOS, so I'm wondering if my problem is related to Windows 7 Home Premium 64bit. Do I need Win7 Professional, or should this be working?

Well, as so often, the solution was "Have you tried turning it off and on again?". I took the following steps to fix the problem:

  • Disabled VT in the BIOS (Advanced BIOS features -> CPU feature -> Virtualization)
  • Boot, shutdown (cold restart)
  • Re-enabled VT
  • Boot, shutdown (cold restart)

Now VMware works as expected. So my problem definitely was not related to having Home Premium.
