Same here, using Mitaka and dnsmasq process only are launched with --domain=mydomain when changed the dhcp_domain option in dhcp_agent.ini.

You need to checK your apache configurations. This error can have a lot of sources. If you installed using apache checK the logs to see about the error.

2017-06-06 07:45:54 -0500 answered a question IPv6 with Global Scope not getting assigned when VM Boots up

Could you show how you configured the subnets? For example, what is the combination of the parameters --ipv6_ra_mode and --ipv6_address_mode?

For example, from docs:

Setting DHCPv6-stateless for ipv6_ra_mode configures the neutron router with radvd agent to send RAs. The table below captures the values set for the address configuration flags in the RA packet in this scenario. Similarly, setting DHCPv6-stateless for ipv6_address_mode configures neutron DHCP implementation to provide the additional network information.

So, you could use tcpdump to see if RA are really being sent from network controller.

I suggest you to create rules in Security Groups to permit all network packets! So, you could debug to define if this really is a configuration problem. Otherwise could be just packets being filtered.

Regards.

2017-06-06 07:32:24 -0500 asked a question How to use --ipv6_ra_mode dhcpv6-stateless --ipv6_address_mode dhcpv6-stateless?

My environment has subnets configured with:

--ipv6_ra_mode dhcpv6-stateless --ipv6_address_mode dhcpv6-stateless

Addresses are well generated (slaac) and VMs have connectivity. But, dhcpv6 requests are not sent. I need that VMs request other information (like nameservers) from dhcpv6 on boot. I've tested manually after boot and it works.

I've seen that the file /etc/network/interfaces.d/50-cloud-init.cfg is generated at boot time. Its content is:

# This file is generated from information provided by
# the datasource.  Changes to it will not persist across an instance.
# To disable cloud-init's network configuration capabilities, write a file
# /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg with the following:
# network: {config: disabled}
auto lo
iface lo inet loopback

auto ens3
iface ens3 inet dhcp

To do what I'm thinking I just need to put these other lines in this configuration file:

iface ens3 inet6 auto
  pre-up sleep 5
  dhcp 1

This was tested, running dhcpv6 manually. Sleep 5 is due a Ubuntu bug and 'dhcp 1' indicates that information should be obtained from dhcpv6 server.

Anyone could suggest how can I get this configuration?

Remenbering that the name of interface is generated by the VMs. For example, in Ubuntu we have ens3 and in Debian eth0. So, bash scripts as user_data to write the interfaces file doesn't looks like a good solution.

I had hope cloud-init could do that.

Thanks.

Same problem here. I followed this reference:

http://docs.openstack.org/kilo/config-reference/content/configure-dashboard.html (http://docs.openstack.org/kilo/config...)

but got this "permission denied" error. I've already tried to change owner to www-data and a lot of permissions combination.

Thanks.
