Re: [libvirt] Mounting a raw DVD

Hello List,

I'm attempting to pass a DVD drive of a headless server into a virtual machine. So far I've managed to mount *something* into the VM, but it's being registered as a blank DVD within the VM. When I mount /dev/dvd into the bare-metal machine it registers normally as the DVD. How do I pass physical drives into a VM and back out using libvirt?
Command used:
#virsh attach-disk Montreal /dev/dvd hdc --mode readonly --driver phy --type cdrom
Connecting to uri: qemu:///system
Disk attached successfully

VM XML file:

<domain type='kvm'>
    <type arch='x86_64' machine='pc-0.11'>hvm</type>
    <boot dev='hd'/>
  <clock offset='utc'/>
    <disk type='file' device='cdrom'>
      <target dev='hdc' bus='ide'/>
    <disk type='file' device='disk'>
      <source file='(Mangled Purposely)'/>
      <target dev='vda' bus='virtio'/>

    <graphics type='vnc' port='-1' autoport='yes' keymap='en-us'/>

I haven't done this for a while but I believe you have to issue a 'detach' command afterwards.
