Windows 10

After upgrade from win8.1 to Win 10 my Virtual box 4.3.2 would not start after upgrade to virtualbox 5.0 I get this error when I try to run a VM AMD-V is not available. (VERR_SVM_NO_SVM). Return code: E_FAIL (0x80004005) component: ConsoleWrap Maps: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}

Any difference with the latest test build from here? If you still see this error, please attach a VBox.log file from such a VM session.

Please reopen if you still have problems with VBox 5.0.2 and you provided the VBox.log file I asked for.

I can confirm this issue. Virtualbox 4.3.2 was runing without problems. After upgrade from Windows 8.1 to Windows 10 VirtualBox did not start any more (not even the VirtualBox Manager). I upgraded to the latest 5.0.3 test build. The VirtualBox Manager opens again. But starting the VM fails with the error message reported above. I attached a VBox.log. SVM is enabled in BIOS.

Could you also attach a VBox.log file when you ran this guest with VBox 4.3.2?

You can close the ticket. The problem was not caused by VirtualBox. Instead, the upgrade to Windows 10 automatically installed Hyper-V and I had to stop the Hypervisor by running the following command as admin: bcdedit /set hypervisorlaunchtype off

Now, VirtualBox is running again.
