Cannot generate OpenStack image #7

Closed TheChymera closed 6 years ago

TheChymera commented 6 years ago

Generating an openstack image currently fails:

Turns out the offending line of code is:

builder ~/NeuroGentooProject/BuildServer # losetup --show -f roots/stemgentoo/openstack_images/image_20180109
losetup: cannot find an unused loop device

This might be failing due to a problem with the kernel module:

builder ~/NeuroGentooProject/BuildServer # modprobe loop
modprobe: FATAL: Module loop not found in directory /lib/modules/4.14.8-gentoo-r1

@Doeme any input on this? IF you agree that this is the issue - how exactly did you integrate the kernel config into the generation of new images? We would want to make sure that all buildserver-type images will be created with a kernel which can build images.

I extended the kernel config used by the Gentoo openstack team, but it is very minimal, so it probably doesn't have lodevs enabled.
