Even though vbox-kvm hasn’t really be updated recently, it still works. I still find it to be the fastest I’ve worked with on linux hosts. The issue for the last few virtualbox releases though as been in compiling from source, you have to omit guest additions from the config.kmk
Get all the dependencies in order on your host machine and follow the instructions from the vbox-kvm github, but right before you issue the final kmk you need to go into Config.kmk and change this config option:
VBOX_WITH_ADDITIONS = 1

VBOX_WITH_ADDITIONS =
Then, you will get a successful compile. It’s been this way for the last many releases. After compile, you can go get the additions inside the guest OS.
