Create an operating system tailored for VirtualBox.
Consider setting up a custom OS inside VirtualBox by using lightweight distributions like Arch Linux. You can install only the essentials and remove unnecessary software. Another option is to use a minimal Linux image and configure it for your needs. Let me know if you'd like more details!
The top choice is a lightweight, low-overhead solution that connects directly to hardware with minimal resources.
Arch offers the newest features, while Debian provides more stability. Xen focuses particularly on this goal.
I intended to test it on a laptop using one single hard drive and 2-3 operating systems. I planned to format it as VHD and then run it via VirtualBox. That would let me use Arch as the base system and switch to Ubuntu or another virtualized OS.
But none of these alternatives fit either. You still require a kernel to handle storage, network, interface, booting, and similar tasks. So just install Fedora or Ubuntu (though choosing a different distro can be tricky). Then use KVM on Linux—it's superior to VirtualBox.
