Setting up VirtualBox within VirtualBox but receiving only 32-bit choices
Setting up VirtualBox within VirtualBox but receiving only 32-bit choices
Windows 7 runs inside Ubuntu, then Ubuntu installs VirtualBox, which in turn runs on Ubuntu. When you try to install Ubuntu again inside a VM, the system only shows a 32-bit option. This is likely because the virtual environment restricts the OS type. To get a 64-bit OS inside a VM, you may need to adjust settings or use a different setup. Let me know if you'd like more details.
You seem confused about the setup. I put a virtual machine inside another one... Are you running a 64-bit version of Ubuntu? Also, I’ve only used 32-bit versions of Ubuntu on XP in 7, so I’m not entirely confident.
Yes, Windows and the initial Ubuntu version are 64-bit, but I couldn’t download the third one since it’s 32-bit and I don’t have a 32-bit Ubuntu installation on my computer at the moment.
VirtualBox and VMware Player/WS are Type 2 virtualization tools. You need a Type 1 hypervisor like Linux KVM, ESXi, or Windows HyperX. This is due to hardware limitations in virtualization, such as Intel Vt-d/vt-x and AMD-Vi/IOMMU features. In short, it’s a restriction based on how much processing power the CPU can handle for virtual instructions. Each virtual machine runs in its own sandbox, so running one inside another causes memory and CPU issues. You might manage basic paravirtualization within one VM to mimic another, but performance will likely be poor or nonexistent.
Trying to place a third VM3 inside VM2 isn't feasible with VirtualBox. You experienced issues similar to what you described—nested VMs on older systems with performance problems. It might be due to hardware constraints or configuration conflicts.
Open the BIOS and turn on the virtualization feature for the CPU. The process varies for AMD and Intel systems.
Running another VM inside it could severely impact performance. Fascinating. I assumed a Type 2 hypervisor like VM Player or Workstation wouldn’t be feasible. If it does function, I expect it to be extremely slow...
Oh, there was a mix-up... I’d never manage a virtual machine inside another one!
