  CloudStack data source cannot determine Virtual Router address on
  RHEL/CentOS 8

Status in cloud-init:
  Fix Released

Bug description:
  The problem: cloud-init is unable to determine CloudStack Virtual
  Router address on RHEL/CentOS 8 machines.

  Why: because RHEL/CentOS 8 does not support systemd-networkd and
  NetworkManager lease files format cannot be parsed by current cloud-
  init CloudStack data source implementation.

  Please see more details about this in merge request
  https://github.com/canonical/cloud-init/pull/141: changes from this
  request were successfully tested.

  What else: most likely other data sources also have the same problem.

[Yahoo-eng-team] [Bug 1528977] [NEW] Neutron router does not work with latest iproute package included in CentOS-7.2-1511

2015-12-23 Thread Andrew Poltavchenko 
Public bug reported:

Seems that something has been changed in the new iproute version and now
attempts to add more than one interface to router cause errors posted at
the bottom. This affects neutron-l3-agent on CentOS-7.2-1511 and
possible on RedHat (cannot check this).

Quick solution is to simple downgrade the package:
# wget 
http://mirror.centos.org/centos/7.1.1503/os/x86_64/Packages/iproute-3.10.0-21.el7.x86_64.rpm
# yum -y downgrade ./iproute-3.10.0-21.el7.x86_64.rpm
