[Xen-devel] HEADS UP: HVM cdrom/disk configuration changed

["Christian Limpach" <christian.limpach@xxxxxxxxx>]

Hi,

Changeset 10921:4c2fab8f8c34 changes how disk and cdrom drives are
configured for hvm domains.  Disks no longer need the ioemu: prefix,
it is ignored if it is present.  Cdrom drives are now configured like
disks by adding a :cdrom suffix to the target device (i.e.
'file:/root/mytest.iso,hdc:cdrom,r').  There is no default cdrom drive
any longer, to create an empty cdrom drive, use ',hdc:cdrom,r'.  Any
of the 4 ide devices can be cdrom drives now.

There is no compatibility support for the cdrom= option in old config
files.  I'll consider patches to add such compatibility support.  The
compatibility code should be implemented in xm.

 'file:/root/mytest.iso,hdc:cdrom,r'
- don't create default cdrom drive anymore - to create default empty
 cdrom drive use: ',hdc:cdrom,r'
