[Xen-devel] [PATCH OSSTEST v2 2/2] Make guest cdrom empty after installation completes

[Wei Liu <wei.liu2@xxxxxxxxxx>]

Previously an iso image that contains nothing was inserted to cdrom
after guest installation had finished.

With this patch we make cdrom really empty.  This helps catch bug that
prevents booting hvm guest with empty cdrom drive.

Remove empty iso image generation in ts-{debian-hvm,redhat}-install as
well.
