Hi everyone,
I see advice in replacing RabbitMQ with ZeroMQ. I've been running 2
clusters Liberty/CentOS7 with RabbitMQ now for while. The larger
cluster consists of 3x Controllers and 4x Compute nodes. RabbitMQ is
running is HA mode as per:
http://docs.openstack.org/ha-guide/shared-messaging.html
Hi,
I'm trying to do a simple customization to my Liberty/CentOS7
dashboard changing my Splash-Logo and after login, the small top-left
Logo.
I have tried to follow the online customization guide and created by

Hello, I got Error, no valid host was found while trying to provision

thx Clint! okay I will stick to RabbitMQ for now. Do you know any good
up2date guide for replacing RabbitMQ with ZeroMQ, or is the general
documentation http://docs.openstack.org/developer/oslo.messaging/zmq_driver.html
have you tried this?
I'm also not sure if the ZeroMQ support is here to stay,

Hi,
I wonder if there's any way of allowing my users to select fixed IPs for
the VMs? I do shared Provider networks, VLAN on Liberty/CentOS.
I know nova boot from the CLI or API has *v4-fixed-ip=ip-addr* option,
however is there any way in the Dashboard where the User can select static
IP?
I wou
and it’s gonna work.

Hi,
I changed a hostname on my cinder node, and now I can see two entries

How do I delete the old entry, there is no 'cinder service-delete'? In
meantime, I have disabled the old service.
Google mention cinder-manage, but I don't have that tool available on
my server Li
Thanks everyone for your replies! I did a safe select first to make

output.

Hi matt, the hardware depends on your workload requirements,
especially when we are talking latency. I do Dell PE R630s for

When I create projects with quotas configured, e.g. number volumes 8, and

I've been debugging cinder api.log and there are no errors. I believe it is

hi all, I have verified this and it seems to be a bug in horizon quota
related. The bug exist in Liberty, when running from Horizon master
pointing at the same deploy it works perfectly fine. thanks will

The live migrations works fine for Windows2012R2 and Ubuntu1404 VMs.

yes thx Corbin, I should try setting mem_stats_period_seconds = 0 in
libvirt section of nova.conf and then restart nova-compute on all hosts.
Then I can try the live-migration again and see if that prevents VMs from
unexpected shutdowns.
Hopefully this works, and maybe this goes away with 7.3 when
thanks everyone, I verified setting mem_stats_period_seconds = 0 as

While this seems to be a workable workaround I'm not sure what's the plans
to permanently fix this in CentOS7.2? th

My storage backend is CEPH. Can anyone advice if I can as a safe
