Re: [Xen-users] Xen How to pass the whole physical hard disk (raw disk) to vm

I think the signed driver you provided is intended for hvm windows. 

For linux vm like Debian, do I need GPLPV driver? I noticed that I accidentally create the NAS vm (Debian) with —hvm. That could be the reason that I can’t use bus “virtio”. Instead, libvirt changed the bus to “ide”.

That makes sense, in xl we use "phy" for block/raw devices or "file" for image files!

Now that I look better the guide gives and example for "cdrom"

<disk type='block' device='cdrom'>
  <driver name='phy'/>
  <source dev='/dev/hdc'/>
  <target dev='hdc'/>
  <readonly/>
</disk>

Anyway, since I'm no expert with vrish I suggest doing it like Felix suggests leaving the driver out might be the best option.

Also, if you want to use "virtio", or in this case (xen) paravirt, you can set recent and signed drivers from:

As a side note, this ones work even in none Linux Dom0's like NetBSD.
