I can get the 9.0 sim to boot fine in VirtualBox 5.1.x, but when trying 9.1 or 9.2 the boot process halts almost immediately:
BTX loader 1.00 BTX version is 1.02
Consoles: internal video/keyboard
BIOS drive A: is disk0
BIOS drive C: is disk1
BIOS drive 😧 is disk2
BIOS drive E: is disk3
BIOS drive :F is disk4
BIOS 639kB/3668920kB available memory
FreeBSD/x86 bootstrap loader, Revision 1.1

That's it. It probably starts loading some binary which subsequently hangs.
Is anyone running 9.1 or 9.2 in VirtualBox without issues? 9.0 works rather well but seems to have intermittent network connectivity issues.
