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? - JLC On Fri, Jan 20, 2017 at 11:47 AM, George Mihaiescu <lmihaie...@gmail.com> wrote: > Check if the flavour you chose has a large enough root disk. > > On Jan 20, 2017, at 08:25, Jorge Luiz Correa <corre...@gmail.com> wrote: > > Hi, I need some help with images that I can't boot.
