Yes!
I've got disk0_dev="sparse-zvol" in my vm-bhyve config file.

# zfs get volmode zroot/vm/f11b/disk0
NAME                 PROPERTY  VALUE    SOURCE
zroot/vm/f11b/disk0  volmode   default  default

# sysctl vfs.zfs.vol.mode
vfs.zfs.vol.mode: 1

I.e. "geom"

Should I change that to "dev"?

While I know I can change only one volume at a time, how would this 
impact Windows VMs?
