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
