Trouble Shooting

Error: VERR_VMX_MSR_LOCKED_OR_DISABLED

This issue may occur no matter which host operating system you’re using. The reason for this might be:

  • you’re not using a CPU that supports hardware virtualization
  • your BIOS does not support hardware virtualization properly
  • hardware virtualization is disabled in your BIOS settings (check it!)
  • there is a bug in your current BIOS version

regarding Known Workarounds Disable USB for the virtual machine

  • Reduce the amount of CPU cores to 1
  • upgrade your BIOS to the latest version (this might be dangerous)
  • Disable VT-X/AMD-V
  • Disable 3D acceleration
  • Shutdown your host machine, unplug (!) from electricity for say 30 secs, reboot then
