virtmanager and boxes for qemu/kvm have freed me from the accursed Oracle product and it’s dkms modules
I still use VirtualBox but a version built to work with KVM.

It does not need a kernel module or DKMS because it uses KVM.
Oracle is accused though.
Remember : using virtualbox at work is not free
And… you need the correct licenses for any Windows VMs.
So those Windows 2025 servers running on your laptop needs a license too… or use Linux…
I keep forgetting that Virtual Box exists because Hyper-V has been available since Win7 and nix has qemu or KVM for native virtualisation.
I still use Virtualbox, configuration is way easier with the GUI and defaults don’t pass any USB devices.

To be fair you can pair KVM/qemu with any GUI manager and have a similar interface to VirtualBox/Hyper-V/VMWare/etc. virt-manager (https://virt-manager.org/) is a popular one for example, I just started using it and it seems to work well for what I need.
Normally I’ve been using VirtualBox but for whatever reason it asks me to recompile the kernel on Debian 13 just to launch. Meanwhile qemu just works.
You can use VirtualBox with KVM as well.

You are probably not recompiling the kernel but rather just a kernel module (DKMS). Still annoying.
You do not need a kernel module for the version above as it KVM is already in the kernel. That is why QEMU does not need a kernel module either.
VirtualBox also has snapshots, which is useful when the VM is used to “play around the OS” and possibly break the OS, such as sandboxing a custom OS build, checking out a malware, etc
KVM/Qemu and Hyper-V also have snapshots, but hyper-v has a dumb name for them that I always forget.
Yup. Virtualbox has some really sane defaults. It is very easy to use.
