The UEFI code in vm-bhyve is currently limited to using slots 4/5/6 for disks so you should only see 3... (I put a CD device on slot 3) If you look in the /path/to/guest/vm-bhyve.log log file you'll probably see something like "ending disks as disk2 due to UEFI limitations". I've never been 100% on which guests have the limitation and which don't, so in UEFI mode I played it safe and just used the 3 slots. If you run the guest with the grub loader instead of UEFI you should get all the disks. If you want, you can comment out the limitation in the vm-bhyve source and see if the guest will pick up the extra disks. It's the 4 lines after the "can't go past slot 6" comment around line 364 of lib/vm-run. If it works it may be worth me adding a configuration option to toggle this limit. As mentioned in my last email FreeBSD CURRENT (12) now supports up to 32 disks per ahci device, and I've successfully had 8 disks in Windows using just 1 pci slot. This won't be in 11.0 unfortunately (as far as I'm aware) but I hope it gets merged into a future 11 release. Matthelp
