This is visible in v2.5.0 build from sources, v2.5.0 from Ubuntu Xenial and v2.1.2 from Debian Jessie. The image in question was converted from vmdk using: qemu-img convert -O qcow2 file.vmdk file.qcow2 The image contains Ubuntu with grub. I can provide debug logs, but will need guidance how to enable them(and what logs are necessary). As a side note, it seems that booting is more certain after connecting(or mounting) partition using qemu-nbd/mount.
