I have an ISO datastore. In that datastore I'm using symlinks to
point to my ISOs on an NFS share. All was working great.<br>
<br>
Along comes Black Friday and a shiny new 3TB hard drive. Out goes
the 5 yo old 500gb drive with EXT 4 and in comes new 3TB drive with
BTRFS.<br>
<br>
I installed new drive, shutdown VMs and use tar c | tar x to move
data over. unmount old, remount new. Fire up VMs, all us well.
Create new VM, attach boot ISO and I get:<br>

past...Follow the suggestions...Run the nfstest python script,
passes, check getsebool shows virt_use_nfs --> on.<br>

If I copy the ISO directly to the directory it works fine. What am
