Yes, I've tried with 0 (without define a minimum size) and with large
sizes. Same error.

Two things that I've noted:

1) When I create a volume based on the image, I can boot the system
normally. But, when I try to launch the instance as ephemeral disk (without
volume on storage), I get the error.

2) When I use 'file' to compare the backing file on compute nodes (the
image that compute nodes download from glance on controller, in
/var/lib/nova/instances/_base) I see different information between the
Cirros image (that works) and Ubuntu (that fails).

file Cirros -> DOS/MBR boot sector; GRand Unified Bootloader, stage1
version 0x3, stage2 address 0x2000, stage2 segment 0x200

file Ubuntu -> DOS/MBR boot sector

Could this be the problem?
