Just to add, if you're using vm-bhyve you should be able to add this with the
diskX_opts template/config option
I may adjust the sample templates to include a sectorsize option for Windows
guests, although I'm not 100% clear on what exact OS versions or applications
require specific settings. I do know that SQL Server has been reported to
suddenly fall over unless a valid block size is used (although I believe it did
install and run), but again I'm not sure exactly what the "correct" settings
Also note that you shouldn't need any grub_* template options if you're using
UEFI. Those options only apply to grub-bhyve.
