CD, DVD and ISO Images

You can export a compact disc (CD) or digital versatile disc (DVD) the same way you export any regular disk. To export a CD or DVD to a guest domain, export slice 2 of the CD or DVD device as a full disk; that is, without the slice option.

Note - You cannot export the CD or DVD drive itself; you only can export the CD or DVD that is inside the CD or DVD drive. Therefore, a CD or DVD must be present inside the drive before you can export it. Also, to be able to export a CD or DVD, that CD or DVD cannot be in use in the service domain. In particular, the Volume Management file system, volfs service must not use the CD or DVD. See How to Export a CD or DVD From the Service Domain to the Guest Domain for instructions on how to remove the device from use by volfs.

If you have an International Organization for Standardization (ISO) image of a CD or DVD stored in file or on a volume, and export that file or volume as a full disk then it appears as a CD or DVD in the guest domain.

When you export a CD, DVD, or an ISO image, it automatically appears as a read-only device in the guest domain. However, you cannot perform any CD control operations from the guest domain; that is, you cannot start, stop, or eject the CD from the guest domain. If the exported CD, DVD, or ISO image is bootable, the guest domain can be booted on the corresponding virtual disk.

For example, if you export a Oracle Solaris OS installation DVD, you can boot the guest domain on the virtual disk that corresponds to that DVD and install the guest domain from that DVD. To do so, when the guest domain reaches the ok prompt, use the following command.

ok boot /virtual-devices@100/channel-devices@200/disk@n:f

Where n is the index of the virtual disk representing the exported DVD.

Note - If you export a Oracle Solaris OS installation DVD and boot a guest domain on the virtual disk that corresponds to that DVD to install the guest domain, then you cannot change the DVD during the installation. So you might need to skip any step of the installation requesting a different CD/DVD, or you will need to provide an alternate path to access this requested media.

How to Export a CD or DVD From the Service Domain to the Guest Domain

From the service domain, check whether the volume management daemon, vold, is running and online.

service# svcs volfs
STATE          STIME    FMRI
online         12:28:12 svc:/system/filesystem/volfs:default

Do one of the following.
- If the volume management daemon is not running or online, go to Step 3.
- If the volume management daemon is running and online, as in the example in Step 1, do the following:
1. Edit the /etc/vold.conf file and comment out the line starting with the following words.
```
use cdrom drive....
```
  See the vold.conf(4) man page.
2. Insert the CD or DVD in the CD or DVD drive.
3. From the service domain, restart the volume management file system service.
```
service# svcadm refresh volfs
service# svcadm restart volfs
```

From the service domain, find the disk path for the CD-ROM device.

service# cdrw -l
Looking for CD devices...
   Node                   Connected Device                 Device type
----------------------+--------------------------------+-----------------
/dev/rdsk/c1t0d0s2    | MATSHITA CD-RW  CW-8124   DZ13 | CD Reader/Writer

Export the CD or DVD disk device as a full disk.

primary# ldm add-vdsdev /dev/dsk/c1t0d0s2 cdrom@primary-vds0

Assign the exported CD or DVD to the guest domain.
The following shows how to assign the exported CD or DVD to domain ldg1:
```
primary# ldm add-vdisk cdrom cdrom@primary-vds0 ldg1
```

Exporting a CD or DVD Multiple Times

A CD or DVD can be exported multiple times and assigned to different guest domains. See How to Export a Virtual Disk Back End Multiple Times for more information.

How to Export an ISO Image From the `primary` Domain to Install a Guest Domain

This procedure shows how to export an ISO image from the primary domain and use it to install a guest domain. This procedure assumes that both the primary domain and the guest domain are configured.

For example, the following ldm list shows that both the primary and ldom1 domains are configured:

# ldm list
NAME             STATE    FLAGS   CONS    VCPU  MEMORY   UTIL  UPTIME
primary          active   -n-cv   SP      4     4G       0.3%  15m
ldom1            active   -t---   5000    4     1G        25%  8m

Add a virtual disk server device to export the ISO image.
In this example, the ISO image is /export/images/sol-10-u8-ga-sparc-dvd.iso.
```
# ldm add-vdsdev /export/images/sol-10-u8-ga-sparc-dvd.iso dvd-iso@primary-vds0
```
Stop the guest domain.
In this example, the logical domain is ldom1.
```
# ldm stop-domain ldom1
LDom ldom1 stopped
```
Add the virtual disk for the ISO image to the logical domain.
In this example, the logical domain is ldom1.
```
# ldm add-vdisk s10-dvd dvd-iso@primary-vds0 ldom1
```

Restart the guest domain.

In this example, the logical domain is ldom1.

# ldm start-domain ldom1
LDom ldom1 started
# ldm list
NAME             STATE    FLAGS   CONS    VCPU  MEMORY   UTIL  UPTIME
primary          active   -n-cv   SP      4     4G       0.4%  25m
ldom1            active   -t---   5000    4     1G       0.0%  0s

In this example, the ldm list command shows that the ldom1 domain has just been started.

Connect to the guest domain.

# telnet localhost 5000
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

Connecting to console "ldom1" in group "ldom1" ....
Press ~? for control options ..

Verify the existence of the ISO image as a virtual disk.

{0} ok show-disks
a) /virtual-devices@100/channel-devices@200/disk@1
b) /virtual-devices@100/channel-devices@200/disk@0
q) NO SELECTION
Enter Selection, q to quit: q

In this example, the newly added device is /virtual-devices@100/channel-devices@200/disk@1.

Boot the guest domain to install from the ISO image.
In this example, boot from the f slice of the /virtual-devices@100/channel-devices@200/disk@1 disk.
```
{0} ok boot /virtual-devices@100/channel-devices@200/disk@1:f
```
