Adding some additional testing I performed.

Just to ensure I didn't have some anomaly in my test system described above
(given that your internal test showed that running on Windows server 2016
HYPER-V didn't seem to reveal a problem running with virtual SCSI drives - I
can't replicate this as I don't have the server version of Windows), I repe=
ated
a test with another pc, running same O/S platform  as my test platform (Win=
dows
10PRO64 - but older 3rd gen Intel CPU platform, i5-3570K, 16 GB RAM).   That
system is running a VM image of NAS4FREE 10.3 based on FREEBSD 10.3
successfully with a ZFS volume of 4 drives using RAID-Z1 resiliency.

I created a new VM with newer NAS4FREE 11.1 image and imported the config f=
ile
of the 10.3 NAS image which all ran fine, however the SCSI-defined disk dri=
ves
attached to VM were no longer visible - same problem as reported on my test
platform.   I've done enough testing to know that this process  doesn't dam=
age
the content of an existing ZFS volume, so I wasn't concerned about going ba=
ck
to 10.3 after doing this (which worked fine).=20=20=20

If NAS4FREE 11 with FREEBSD11 runs fine in the Server 2016 version of HYPER=
-V
but not on the desktop version (which is the same series - Server 2016 late=
st
and W10 PRO Creators' Update then it begs the question as to what is differ=
ent
with those 2 platforms as it relates to virtual machines with integrations
services and how FREEBSD11 works with them differently than 10.3 did.=20=20=
=20

In the NAS4FREE support forum, someone else also reported running into this
problem with VMWARE ESX hypervisor but don't know which version so that led=
 me
to think that HYPER-V was not be cause.
