When network type is ipv6_dhcpv6-stateful, cloud-init seems to enable dhcp for both ipv4 and ipv6. Network manager prefers dhcp over ipv4 and hence dhcp6 is not used to obtain the IP address. This is incorrect. For ipv6_dhcpv6-stateful networks, we should set: ipv4.method = disabled // disables all ipv4 dhcp ipv6.method = dhcp ipv6.may-fail = no // dhcp6 must succeed. For ifcfg files (sysconfig renderer), the corresponding changes should be: BOOTPROTO = none // instead of dhcp so that dhcp4 is disabled. IPV6_FAILURE_FATAL = yes // so that dhcp6 should succeed. This patch fixes this. This patch has been tested by Red Hat QE and it seems to fix the above issue.

Proposed Commit Message
Adding BOOTPROTO = dhcp to render sysconfig dhcp6 stateful on RHEL
BOOTPROTO needs to be set to 'dhcp' on RHEL so NetworkManager can
properly acquire ipv6 address.
rhbz: #1859695
Signed-off-by: Eduardo Otubo otubo@redhat.com
Additional Context
The original bz 1859695 is mostly marked as private but the bug as noticed while configuring an internal IPv6 network on Openstack between the instance and an NFS storage. No patch required or bug noticed if the instance was configured with a regular ipv6/dhcp interface.
Test Steps
(as described on the above mentioned BZ)
Steps to Reproduce:
Actual results:
The Nova assigned IPv6 address was not assigned to device Eth1
Expected results:
Expected the Nova assigned IP address to be assigned to Eth1 interface
