2015-05-29 13:49:54 -0500 commented answer cinder-api and bind_host parameter

Thanks for pointing me to the cinder-volume A/A problem.

For cinder-api, even if i set my_ip to, the bind occurs on *:8776 and not on To work around the problem, i set the cinder endpoint and the VIP to port 8777.

2015-05-28 20:29:46 -0500 asked a question cinder-api and bind_host parameter


My 3 controllers run all OpenStack APIs and HAProxy service. I must tell to cinder-api to run on a specific IP address to avoid conflict with HAProxy (port 8776) but i can't find how. For Glance, i used the bind_host variable to do that but it doesn't works with Cinder.

I looked in this documentation but i found nothing.

Thanks for your help.

I had the same issue with Kilo and HAProxy setup. glance image-list worked fine but nova image-list gave me the same error as yours.

I solved the problem by setting registry_host value to point to my virtual IP in glance-api.conf :



registry_host = vip-int

I already had this problem. Are you installing OpenStack on a virtual machine? If yes, you have to change the hypervisor type in /etc/nova/nova.conf. Search for virt_type and change it from 'kvm' to 'qemu'.

2014-07-27 20:50:35 -0500 edited question Terminating LXC instance fails

LXC instance fails to terminate with this message in nova-compute.log :

libvirtError: Failed to kill process 1618: Permission denied

1618 ? 00:00:00 dhclient

If i kill this process before trying to terminate the instance, it works.

I have this problem with the official Ubuntu 14.04.1 cloud image and also with my own LXC images created with lxc-create.

Thanks for your help.
Host system: Ubuntu 14.04.1, Icehouse and LXC 1.0.5

I replaced dhclient with dhcpcd in my Ubuntu image and the problem is gone. The instance get his IP from Nova and it can be terminated without error. For dhclient, maybe something in dhclient.conf could solve the problem?
