[vbox-dev] (Bug?)VT-Bit

[Michal Necasek]

Thanks. Unfortunately, the log files were cut off too early due to the VM startup failure :( 

Could you please paste into the e-mail (or attach) the output of 'sysctl machdep' from your system? That will give us the information missing from the log. 

Regards, 
Michal

I also tried VBoxManage modifyvm Tiger --hwvirtex off VBoxManage modifyvm Tiger --vtxvpid off, from the command line, with VBox not running, and with it running, same result as my last post.

Could you please provide a VBox.log? You can just attach it to the e-mail. That will tell us what's going on.

I changed my CPU from one that supports VT-x to one that doesn’t, now none of my virtual machines will run 



Failed to open a session for the virtual machine Tiger . 
VT-x is not available (VERR_VMX_NO_VMX). Result Code: 	NS_ERROR_FAILURE (0x80004005) 
Component: 	ConsoleWrap 
Interface: 	IConsole {872da645-4a9b-1727-bee2-5585105b9eed} 

I edited the .vbox-prev of the virtual machines, and added: 


<HardwareVirtEx enabled=“false”/> 


But every time I launch VB, it overwrites the settings, removes <HardwareVirtEx enabled=“false”/>. 


I can’t access the Acceleration tab in VB, it’s greyed out, but it must have the VT-x checkbox checked? 


Is there some preference file I need to delete? 


macOS Sierra 10.12.2 


VB 5.1.14 r112924 (Qt5.6.2)
