I am switching to VirtualBox from VMware Player because I want more network options. VMware_Player has been working fine with my 64bit isos. I uninstalled VMware Player. The 64bit options show up in VirtualBox when I boot into safe mode but don't show up when I boot normally.

When I try to launch a 64bit machine in VirtualBox, it says "AMD-V is disabled in the BIOS (or by the host OS) (VERR_SVM_DISABLED)" but I have Virtualization enabled in the BIOS. I have tried the BIOS setting with it on and off, neither works. I do have Android Studio installed if that makes any difference. VirtualBox "Version 5.1.10 r112026 (Qt5.6.2)"

I have tried reinstalling VirtualBox mulitple times.

It seems like windows or some program is blocking or using the AMD-v. I have spent hours trying to fix this.

What do you think could cause this? Do you have any idea how to fix it? Any help would be appreciated! Thanks

Here are some pictures:

  • If virtualization is enabled in the bios then it might be that you have HyperV enabled in the Windows optional programs applet, or I have seen some antivirus tools that steal or block virtualization. Right click the Windows button and go to "programs and features" then in the top left should be optional components, make sure HyperV is unchecked. Otherwise what AV do you use? google.co.uk/… – Mokubai Dec 13 '16 at 7:59
  • I don't know think it's Hyper-v because Windows 7 doesn't support it and there is no option for hyper-v in Windows features. I use Bitdefender but I also have Malwarebytes installed. Would either of those do it? – DarinL Dec 13 '16 at 8:06
  • LeoMoon CPU program says that AMD-v is supported but not enabled. – DarinL Dec 13 '16 at 8:14
  • I doubt either of those would do it. The fact that it work in safe mode suggests that there is something stealing it from the OS hence my comment. Perhaps an important part of VMware Player got left behind. – Mokubai Dec 13 '16 at 8:24
  • Thanks! That is definitely possible. Is there any way to tell what is using(grabbing) it? Also there are still some VMware registry entries. – DarinL Dec 13 '16 at 8:28

In my case I had to: Disable it in BIOS, boot in windows, restart and re-enable it.
