Hardware Virtualization 4.3 Not Working

[meatwad64]

I'm getting an error with 4.3 that says VT-x/AMD-v is not enabled. I double checked that hardware virtualization is enabled. I have used Hyper-V which requires Hardware Virtualization and it works fine.

I have attached the log.

Something is using VMX and preventing VirtualBox from accessing it. If Hyper-V is still installed you will need to set it to not load on boot.

[meatwad64]

I didn't realize Hyper-V got exclusive access to VMX but I removed hyper-v. I now get this error trying to install Windows 7:

Attempting to load a 64-bit application, however this CPU is not compatible with 64-bit mode.

I have attached the latest logs.

I would do a complete shut down and start instead of a warm boot. I am seeing VMX code but it does not finish like it should.

[meatwad64]

I did a shutdown and a cold boot but it still is giving me the same error. Any other ideas?

From the hosts terminal/command window type VBoxManage showvminfo <VM Name> --details and post here. Replace <VM Name> with the actual name of the VM. Use " " if the name has a space in it.

Note if the host is Windows you need to be in the directory that has VBoxManage.exe for the command to work.

Here is the output from that:

Here's your problem, but I have no idea what to tell you since I have never encountered it before.

Code: Select all

00:00:00.492839 HM: Guest support: 32-bit only.

Maybe you need to update your bios, but other than that you would need to post a ticket at bugtracker

[meatwad64]

OK. I will have to file a bug. I know the 64-bit VMs worked with 4.2.x. It sounds like a regression. I just installed the latest BIOS a few weeks ago.

Thanks!

[Ramshankar]

Change the guest OS type to 64-bit.

Via the GUI: Settings -> Basic Tab | Version

Via the command-line:

Code: Select all

VBoxManage modifyvm <vmname> --longmode on
