According to VMWare's documentation 'cdrom-raw' is an acceptable value
for deviceType for a CD-ROM drive. The documentation states that the VMX
configuration for a CD-ROM deviceType is as follows:
ide|scsi(n):(n).deviceType = "cdrom-raw|atapi-cdrom|cdrom-image"
>From the documentation it appears the following is true:
- cdrom-image = Provides the ISO to the VM
- atapi-cdrom = Provides a NEC emulated ATAPI CD-ROM on top of the host
CD-ROM
- cdrom-raw = Passthru for a host CD-ROM drive. Allows CD-R burning from
within the guest.
A CD-ROM prior to this patch would always provide an 'atapi-cdrom' is
modeled as:
<disk type='block' device='cdrom'>
<source dev='/dev/scd0'/>
<target dev='hda' bus='ide'/>
<address type='drive' controller='0' bus='0' target='0' unit='0'/>
</disk>
This patch allows the 'device' attribute to be set to 'lun' for a raw
acccess CD-ROM such as:
<disk type='block' device='lun'>
<source dev='/dev/scd0'/>
<target dev='hda' bus='ide'/>
<address type='drive' controller='0' bus='0' target='0' unit='0'/>
</disk>
