-qemu-system-x86_64 does not boot image reliably
-
-Booting image as root user with following command works randomly.
-
-./qemu-system-x86_64 -enable-kvm -curses -smp cpus=4 -m 8192 /root/ructfe2917_g.qcow2
-
-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.
-
-I want a fix ;) and I do expect qemu to get it faster then Ubuntu.
-So I set up Ubuntu Zesty(to fullfill dependencies) and build qemu:
-QEMU emulator version 2.10.1 (v2.10.1-dirty)
-and... it's still there.
-
-Can you tell me how and what logs to provide?
-
-And it still happens on:
-
-QEMU emulator version 2.10.93 (v2.11.0-rc3-dirty)

-
-This looks not a QEMU bug to me. You may drop "-curses" first, and run again. Once get inside, change grub file(/etc/default/grub) by uncomment GRUB_TERMINAL=console. It should work then. If still not, then blacklist vga16fb and add "fbcon=map:99 text" in grub command line. Remember to run update-grub after change configure file.
-
-Have you ever tried the suggestions from Liang Yan ?
