From: Alexandru Avadanii Date: Fri, 25 Mar 2016 16:12:08 +0100 Subject: [PATCH] nova: Fix inject for direct boot with part table. See [1] for full bug description. For now, we detect direct kernel boot with a partition table inside disk image by passing target_partition when root kernel arg points to a partition (instead of the whole disk).
