I have been investigating alternatives, as VMware is currently a non-starter (literally..) with Kernel 5.8..

I installed the latest VirtualBox (6.1.97 r139689) from SVN (another blast from the past…) and managed – after some messing around – to get it to compile OK on my Fedora 32 test system with Kernel 5.8 (from kernel.org..)    I had to disable documentation creation, as this seemed to be incompatible with Fedora?
$ ./configure --disable-hardening --disable-docs --out-path=/opt/VirtualBox

The kernel modules then compiled/installed OK:
$ lsmod |grep vb
vboxnetadp   28672  0
vboxnetflt   32768  0
vboxdrv      430080 2 vboxnetadp,vboxnetflt

After this, I ran the VirtualBox Manager and created a Fedora 32 KDE/Plasma vm, and installed Guest Additions etc..

So far, this seems to be running OK, but is a bit sluggish..

Update August 4th,,

Tried WinXP vm, converted from VMware, and this booted OK, but when I enabled USB support, it crashed.    Fedora 32 VM + USB also crashes..   This seems to match other test reports, where some said ‘it works’ and others reported crashes..
