The libxl driver currently sets the disk backend to LIBXL_DISK_BACKEND_TAP when <driver name='file'> is specified in the <disk> config. qdisk should be prefered with this configuration, otherwise existing configuration such as the following, which worked with the old Xen driver, will not work with the libxl driver
<disk type='file' device='cdrom'> <driver name='file'/> <source file='/path/to/some/iso'/> <target dev='hdc' bus='ide'/> <readonly/> </disk>
In addition, tap performs poorly compared to qdisk.

Thanks Stefano. This is a change that needed blessing from one of the Xen tools devs IMO. I've pushed the patch. Regards, Jim
