I'm using 10.0-RELEASE-p7 as a host, and 9.3-RELEASE as a guest. VM is created using vmrc script, it installed fine. But on attempt to create additional fs inside the vm, newfs just silently fails without writing anything to disk. file -s on a filesystem reports just 'data', instead of the usual "Unix Fast File system" for example, quotacheck also fails from inside the vm - quotacheck: Cannot find file system superblock: No error: 0. I'm getting this error message for a working filesystem, a filesystem created outside the vm and mounted inside it. bhyve uses zvol for a block device, mounted using ahci-hd. Commands used to start the vm are these: /usr/sbin/bhyveload -m 4096 -d /dev/zvol/data/vm/bsd-ix0 bsd-ix0 /usr/sbin/bhyve -c 4 -m 4096 -A -H -s 0,hostbridge -s 2,ahci-hd,/dev/zvol/data/vm/bsd-ix0 -s 3:0,virtio-net,tap8000 -s 5,lpc -l com1,/dev/nmdm0A bsd-ix0
