Description Derek Higgins 2016-10-20 13:52:57 UTC

RHEL 6 images build and boot successfully (built with the following command)

DIB_REG_TYPE= DIB_CLOUD_IMAGES=file://$PWD DIB_RELEASE=6.8-20160425.0 disk-image-create --mkfs-options "-O ^64bit" rhel baremetal dhcp-all-interfaces grub2 -o rhel6-image

(Note: the --mkfs-options "-O ^64bit" is required if building a RHEL 6 image on a RHEL 7 host)

But when the instance boots its not getting any IP address

The problem seems to be that dhcp-all-interfaces isn't being installed correctly as its using dib-init-system to decide how to install itself.
dib-init-system is reporting that the image uses upstart as a init system instead of sysv

Also when localy forcing dhcp-all-interfaces down the sysv path it fails because 

/tmp/in_target.d/install.d/50-dhcp-all-interfaces: line 26: update-rc.d: command not found

We should instead be adding 
# chkconfig:         3 9 50
to the init script header and doing something like
chkconfig dhcp-all-interfaces on

Comment 1 Derek Higgins 2016-10-20 14:47:58 UTC

An update to the previous comment dib-init-system is probably returning the current value (it is upstart on RHEL 6) but the networking is being handled by the sysv compatibility layer.
here
/etc/rc.d/rc3.d/S10network -> ../init.d/network

Comment 4 Derek Higgins 2016-11-15 11:45:46 UTC

Tested using
diskimage-builder-1.21.0-6.el7ost.noarch

Built a rhel6 image with
DIB_RHSM_POOL=$POOL DIB_RHSM_PASSWORD=$P DIB_RHSM_USER=$U DIB_REG_TYPE= DIB_CLOUD_IMAGES=file://$PWD DIB_RELEASE=6.8-20160425.0 disk-image-create --mkfs-options "-O ^64bit" rhel baremetal dhcp-all-interfaces -o rhel6-image

Booted the image and all was well

[cloud-user@undercloud ~]$ ssh cloud-user.2.6 cat /etc/redhat-release 
Red Hat Enterprise Linux Server release 6.8 (Santiago)
