How to Add a Virtual CD-ROM Device to a Kernel Zone

Perform this task to add a virtual CD-ROM device to a kernel zone.

Become a zone administrator.

For more information, see Using Rights Profiles to Install and Manage Zones in Creating and Using Oracle Solaris Zones.
Create an empty removable read-only lofi device in the global zone.
```
global$ pfbash lofiadm -r
```
The following example shows sample output.
```
global$ lofiadm -r
/dev/lofi/1
```

Add the lofi device to the kernel zone.

Output is similar to the following:

global$ zonecfg -z kzone
zonecfg:kzone> add device
zonecfg:kzone:device> set storage=dev:path-to-device
zonecfg:kzone:device> end
zonecfg:kzone> exit

Reboot the kernel zone to apply the configuration changes.
```
global$ zoneadm -z kzone reboot
```
Log in to the kernel zone.
```
global$ zlogin kzone
```
On the kernel zone, update the device file system (devfs) and restart the hardware abstraction layer (hal).
This step enables the hal service to see the virtual CD-ROM device.
```
kzone$ pfbash devfsadm -i zvblk
kzone$ svcadm restart hal
```

On the kernel zone, list the removable devices.

Output is similar to the following:

kzone$ rmformat -l
Looking for devices...
     1. Logical Node: /dev/rdsk/c1d0p0
        Physical Node: /zvnex/zvblk@0
        Connected Device: kz       vDisk            0
        Device Type: Removable
        Bus: <Unknown>
        Size: 16.4 GB
        Label: <Unknown>
        Access permissions: <Unknown>
…

In the global zone, specify a path to an ISO image file to associate with the removable loopback device.

global$ lofiadm -r image-path device-path

The following example demonstrates associating the CD-ROM image /root/sol-11_3-repo.full.iso to the lofi device /dev/lofi/1:

global$ lofiadm -r /root/sol-11_3-repo-full.iso /dev/lofi/1
global$ lofiadm
Block Device             File                           Options
/dev/lofi/1              /root/sol-11_3-repo-full.iso        Removable,Readonly

In the kernel zone, mount the CD-ROM device.

kzone$ mount -F hsfs device-location /mnt

When you are finished using the virtual CD-ROM, unmount it from the mount point in the kernel zone.
```
kzone$ umount /mnt
```
Eject the CD-ROM virtual device in the kernel zone.
```
kzone$ eject cdrom
```

In the global zone, verify that the ISO image is no longer associated with the lofi device.

Output is similar to the following:

global$ lofiadm
Block Device             File                           Options
/dev/lofi/1              -                              Removable,Readonly
