VirtualBox Won't Start Virtual Machine

Project:Trisquel
Component:Programs
Category:bug report

Status:closed
Description

I receive the message below any time that I try to start a VM inside VirtualBox using Trisquel 4. (I'm trying to boot the virtual machine using the gNewSense 2.3 .iso file.) It looks like there's something in the kernel it doesn't like... Failed to start the virtual machine gNewSense. VirtualBox can't operate in VMX root mode. Please disable the KVM kernel extension, recompile your kernel and reboot (VERR_VMX_IN_VMX_ROOT_MODE). Result Code: NS_ERROR_FAILURE (0x80004005) Component: Console Interface: IConsole {6375231a-c17c-464b-92cb-ae9e128d71c3}

I have the same problem. It's because the KVM kernel modules conflict with VirtualBox. I've been using the following workaround: Blacklist the KVM kernel modules. This will stay in effect until you change it back.

  1. At the desktop, press Alt+F2.
  2. Type gksudo gedit /etc/modprobe.d/blacklist.conf in the box.
  3. Click Run
  4. Add the following lines to the end of the file:
    # Conflict with VirtualBox
    blacklist kvm-intel
    blacklist kvm-amd
    blacklist kvm
  5. Save
  6. Quit
  7. Reboot

Should be fixed in version 5.0 (will test this weekend). See:

I use VirtualBox on 5.0 and I don't get this problem. :)

Yes it works normally but do you have qemu-kvm installed? That is because this issue happens specifically when you have both virtualbox and this package installed at the same time.
