I also tried installing Ubuntu 18.04 shell (from windows store) and building on that. Build failed because of underlying structure.
I have a pretty old no-name desktop.
Intel(R) Core(TM) i7-2700K [email protected]
3.50GHz 4.40 GHz (the 4.4 is an overclock
20.0 GB, 64-Bit (Hardware ram is 24GB)
I assign the VBox 90% CPU, 8 cores (4 real cores hyper-threaded), and 12GB RAM
I have multiple drives assigned to the VBox. eg One for system, another for ROM source, and another for Out and another for ccache. Thus reads and writes go to different controllers and thereby occur in parallel. Some drives are RAID1 non-solid state (ie rotating drives), while at least one is a USB3 portable drive!
Even with the VBox, my build time is around 70min for Oreo, and 90min for Q (after CCache is built, ie second build, a cold build is around twice that I think, CCache is on a rotating drive)
