[OmniOS-discuss] zvol devices not seen in child (non-global) zones

[gate03 at landcroft.co.uk]

Hello;  I'm trying to use some raw storage in a non-global zone, as a VirtualBox disk image.  However, although I believe I'm following the correct procedure, the storage is not seen.

First, confirm that 'zfs create -V 15G rpool/vol/Gentoo1' did its work:
	root at world:~# ls -l /dev/zvol/dsk/rpool/vol/Gentoo1 /dev/zvol/rdsk/rpool/vol/Gentoo1
	lrwxrwxrwx 1 root root 0 Jan  9 12:31 /dev/zvol/dsk/rpool/vol/Gentoo1 -> ../../../../..//devices/pseudo/zfs at 0:41
	lrwxrwxrwx 1 root root 0 Jan  9 12:31 /dev/zvol/rdsk/rpool/vol/Gentoo1 -> ../../../../..//devices/pseudo/zfs at 0:41,raw
	root at world:~# ls -Ll /dev/zvol/dsk/rpool/vol/Gentoo1 /dev/zvol/rdsk/rpool/vol/Gentoo1
	brw------- 1 573 100 170, 41 Jan  9 12:39 /dev/zvol/dsk/rpool/vol/Gentoo1
	crw------- 1 573 100 170, 41 Jan  9 12:39 /dev/zvol/rdsk/rpool/vol/Gentoo1

So the volume is there.  I chowned it to 'me' (573:100) in the child zone but it makes no difference if they're owned by root.

Then ensure the zone knows about the zvol:
	root at world:~# zonecfg -z person export
	create -b
	set zonepath=/zone/people
	set brand=ipkg
	set autoboot=true
	set ip-type=shared
	add fs
	set dir=/home
	set special=/home
	set type=lofs
	end
	add net
	set address=192.168.1.3/24
	set physical=e1000g0
	end
	add net
	set address=192.168.0.3/24
	set physical=e1000g1
	end
	add device
	set match=/dev/vboxdrv
	end
	add device
	set match=/dev/zvol/dsk/rpool/vol/Gentoo1
	end
	add device
	set match=/dev/zvol/rdsk/rpool/vol/Gentoo1
	end

Ensure that the zone knows about the changes, then login and check:
	root at world:~# zoneadm -z person reboot
	root at world:~# zlogin person
	[Connected to zone 'person' pts/3]

	root at person:~# find /dev/zvol ! -type d
	root at person:~#

So what's gone wrong there ?
