Hello all,
I am trying to virtualize a dvd-burner (i.e. assign the dvd-burner to the
guest) through HVM (the guest is Windows).
The line in the config file says:
''phy:/dev/dvdrw3,hdc:cdrom,r''
but on the guest side it appears as a read-only (and not perfectly working)
device.
I haven''t tried yet to mark it as ''w'' and I cannot
find documentation about
the disk node.
But the question is: is dvd-burner virtualization supported?
Thanks

GPLPV supports the scsi passthrough so if you are using that you might have some success but I''ve never actually tried it. If you try it and it doesn''t work for burning, send me the details and I''ll see if I can fix it. You do need scsi passthrough backend support in Dom0 though... what Dom0 kernel are you using? James
James, lsscsi reports: [13:0:0:0] cd/dvd Slimtype DVD A DL8ATS XP59 /dev/sr0 As for the kernel I am using Fedora 16 with Xen 4.1.2 out of the repository. -e On Tue, Jan 17, 2012 at 3:09 PM, James Harper <james.harper@bendigoit.com.au> wrote:> > > > Hello all, > > I am trying to virtualize a dvd-burner (i.e. assign the dvd-burner to > the guest) > > through HVM (the guest is Windows). > > The line in the config file says: > > ''phy:/dev/dvdrw3,hdc:cdrom,r'' > > but on the guest side it appears as a read-only (and not perfectly > working) > > device. > > I haven''t tried yet to mark it as ''w'' and I cannot find documentation > about the > > disk node. > > But the question is: is dvd-burner virtualization supported? > > If the DVD burner is seen by Dom0 as a SCSI device then scsi passthrough > should allow it to work. > > GPLPV supports the scsi passthrough so if you are using that you might > have some success but I''ve never actually tried it.
