To expand on this, 'bhyvectl --get-stats' returns lots of info, but no
disk
IO stats.

using ZFS for a dataset.
Apparently ZFS only tracks RW stats for mounted disks, but not raw
disks stored
as a ZFS dataset. Below is a running VM, but the stats reported are all
zero.
kstat.zfs.storage.dataset.objset-0x1d41.nread: 0
kstat.zfs.storage.dataset.objset-0x1d41.reads: 0
kstat.zfs.storage.dataset.objset-0x1d41.nwritten: 0
kstat.zfs.storage.dataset.objset-0x1d41.writes: 0
kstat.zfs.storage.dataset.objset-0x1d41.dataset_name:

Can't use gstat as ZFS datasets don't show up as GEOM devices it
appears.
iostat has the same issue.
'zfs get all' for the dataset in question does not return any RW stats.
Any one have any thoughts on this?
