Hi,
I am not able to boot a vdi image on virtualbox using libvirt .It keeps showing me "Bootable medium not found". I have tried booting it manually with virtualbox GUI and it boots without any problem. May there is some problem with my libvirt domain XML . I also realized on some investigation that it is not detecting the vdi image file as a hard disk (when i am booting from a live cd)
A part of my libvirt domain XML is here:

<os> 
<type>hvm</type> 
<boot dev='hd'/>           
</os> 

<devices>
<disk type='file' device='disk'> 
<source file='disk.vdi'/> 
<target dev='hdd' bus='ide'/> 
</disk>
</devices>

Thanks for replying
