B.17.3.2. Incorrect drive device type

Symptom

The definition of the source image for the CD-ROM virtual drive is not present, despite being added:

# virsh dumpxml domain
<domain type='kvm'>
  ...
  <disk type='block' device='cdrom'>
    <driver name='qemu' type='raw'/>
    <target dev='hdc' bus='ide'/>
    <readonly/>
  </disk>
  ...
</domain>

Solution

Correct the XML by adding the missing <source> parameter as follows:

<disk type='block' device='cdrom'>
  <driver name='qemu' type='raw'/>
  <source file='/path/to/image.iso'/>
  <target dev='hdc' bus='ide'/>
  <readonly/>
</disk>

A type='block' disk device expects that the source is a physical device. To use the disk with an image file, use type='file' instead.
