The error "... but the cause is unknown" appeared for XMLs similar to
this:
<disk type='file' device='cdrom'>
<driver name='qemu' type='raw'/>
<source file='/dev/zero'/>
<target dev='sr0'/>
</disk>
Notice unsupported disk type (for the driver), but also no address
specified. The first part is not a problem and we should not abort
immediately because of that, but the combination with the address
unknown was causing an unspecified error.
