VirtualBox - No 64-bit
-
I just reinstalled VB and now don't have the option to choose 64-bit during setup for VMs... I installed the amd64 version at www.virtualbox.org so I'm stumped... Anyone else ever have this issue?
-
Yup. had that issue.
-
Now you are going to want the answer....
-
Install it twice? (2x32=64)
-
But I'm going to make you sweat for a bit...
-
I had this issue once when I had Client Hyper-V enabled on Windows 10.

Haha k I'll think about this one for a minute...

This is because hardware virtualization is either not enabled in the BIOS, not available on the CPU or for some reason is not being passed through the OS. This is pretty common. 32bit is pretty easy to emulate in software and so VirtualBox does that. VBox predates hardware virtualization assistance just as Xen does.
To virtualize AMD64 you need hardware assistance. So you have to have that enabled and working or VBox can't do it.

I've had this issue in Hyper-V when migrating hosts, but just had to go into processor compatibility... But this is nothing like that, because this is a brand new VM on a brand new installation and I'm just trying to choose a 64-bit VM template.

So I've just already gone through the BIOS, all virtualization is enabled except for some stuff regarding TPM. I know all is enabled that needs to be because I just reinstalled VB was all... and Hyper-V on my local workstation (8.1) works fine.

Is Hyper V enabled on that computer? If so, disable it.
-
Ooooo here's an interesting one. You can't use Hyper-V and VB on the same system, if your BIOS is already setup correctly...

I wonder why that might be.

You beat me to it.

Probably because Hyper-V permanently takes over VT-x instead of sharing like VMware Player for instance (VB forum)... Because it's a level 1 hypervisor?
In either case, sharing is not caring I guess.

Type 1. It has nothing to do with sharing. It is because you are doing nesting. Hyper-V does not support hypervisor nesting. Why do you want to nest your hypervisors?

Correct, because Hyper-V does not virtualize the virtualization functions.
-
Whatever you are wanting to install into VirtualBox you could just install directly onto Hyper-V.

A dev has a vmdk that I tried converting for HV but it just comes up as user: drac and no commands will execute. So basically the conversion is botched. I need to spin up that VM and grab some files that he needs to compare against others. I do everything in HV so I had just wanted to install VB with the intention I'd convert the vmdk (used to be just CLI only but now you can copy to VHD then attach in HV).
So I'm just using VB again as a one time use.
