Bug Description
Booting image as root user with following command works randomly.
./qemu-
Most of the time it ends up on "800x600 Graphic mode"(been stuck there even for 4 hours before killed), but 1 out of ~20 it boots image correctly(and instantly).
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.
Please always use the latest version of QEMU (currently v2.10, soon v2.11) when reporting bugs to the upstream QEMU project - we don't support old versions like v2.5 any more. So I guess you wanted to report a bug agains v2.5 in Ubuntu instead and I changed the target of this bug accordingly.
