   I noticed that when trying to put Linux on laptops
   with the early nvram 'disks'. At the time most GRUBs
   would not recognize them properly, you couldn't boot
   from them. However the GRUB that came with MX Linux
   was a tad smarter. Still have MX on those old laptops,
   hell, have it on THIS newer laptop.

   KVM is perfectly good - UNTIL you want to maybe ENLARGE
   a virtual disk. Then you've gotta edit config files and
   do some other weird stuff. With VBox its just sliding
   a control and VBox does the rest. KVM also uses a custom
   kernel wheras VBox generally doesn't need that.

   All in all, I'd say the two were kinda "even".

   Also tried Xen ... but that seems to have fallen well
   behind the curve at this point and the commercial ops
   are, well, $$$ for not ALL that much extra goodness.

   Anyway, for the poster, I'm still gonna suggest he install
   in a VM on his Winders CrapBox rather than set up dual-boot.

   Tricky thing is setting up VMs on a box so each one seems
   to have its own local IP address, can talk to other machines
   and the net and vice-versa kinda on its own. Tutorials too
   often assume that you don't want to DO that, that you're
   just playin' rather than want multiple virtual servers.
   Hey, if you've got a hot i9 with gobs of ram then lots
   of usable VMs are kinda the logical step.
