Unable to start Windows 7

Post by TomTDM »

Hello All
I'm new to the group and I'm hoping that someone can help. I'm unable to start a Windows 7 VM. The log is attached. I don't get anything in the screen.

Thank You
Tom

The log says you got a Guru Meditation:
00:00:13.675375 !! VCPU0: Guru Meditation -4000 (VERR_VMX_VMXON_FAILED)
This despite:
Host OS:

00:00:12.978881 OS Release: 6.1.7601
00:00:13.136141 HM: HMR3Init: VT-x w/ nested paging and unrestricted guest execution hw support
You probably have 3rd-party Antivirus that recently updated with a 'hardware Virtualization' feature which gets in the way of Virtualbox. Find it & turn it off, then your VMs should start running again.
