2017-01-26 17:07:14 -0600 commented answer Horizon not showing overcommited hypervisor stats?

In that case, how can I tell how much capacity I have left?

2017-01-23 17:13:10 -0600 asked a question Horizon not showing overcommited hypervisor stats?

I've got an all-in-one packstack on CentOS7 install, inside a physical host with the following params: Intel Core i7 (4 cores, 8 with HT), 32GB RAM, 2TB HDD

In the 'hypervisors' view I'm observing the following stats: image description

As far as I'm aware, I'm using the default overcommit values (x16 for CPU, 1.5 for RAM, 1.0 for HDD), therefore I was expecting to see 128vCPUs and ~50GB RAM total.

Can anyone explain what's wrong or what do I need to change to have this dashboard display data corresponding to my setup?

2017-01-10 09:45:56 -0600 commented question Can't access Horizon by hostname

can anyone help?

2017-01-09 14:33:15 -0600 commented question Can't access Horizon by hostname

yes, telnet to port 80 works as well.

2017-01-09 04:41:30 -0600 asked a question Can't access Horizon by hostname
  • I've got 2 machines, A and B.
  • Machine A's hostname is 'mylab'
  • I've installed an all-in-one OpenStack using PackStack on machine A
  • I've modified the host file on machine B so that 'mylab' can be resolved as A's IP.

When accessing: - http://{machine A's IP}/dashboard - I'm seeing the Horizon dashboard as expected - http://mylab/dashboard - I'm getting an Apache-generated 404 error

Obviously, I'd like to access Horizon via the 'mylab' hostname, so what do I need to configure in order to fix this?

Best regards

2015-06-08 23:16:22 -0600 asked a question All in one OpenStack node with Neutron/Midonet networking?

I intend to setup a single all in one node at my office as a technology demonstrator - is it possible to configure Neutron/Midonet networking using a single node only?

What would the prequisites be?

Best regards, Maciej

2013-07-22 02:55:06 -0600 asked a question glance authorization failed: Errno 22 Invalid argument

Hello,

I'm performing an OpenStack manual installation, and I got stuck on the "glance" part.

I believe I've managed to follow the manual to the letter, with minor exceptions such as the IP address.

When verifying the installation I'm getting the following :

[root@localhost images]# glance --debug --verbose --os-username=admin --os-password=secrete --os-tenant-name=demo --os-auth-url=http://localhost:5000/v2.0 image-create --name="CirrOS 0.3.1" --disk-format=qcow2 --container-format bare < cirros-0.3.1-x86_64-disk.img 
Authorization Failed: [Errno 22] Invalid argument

I believe that I've managed to execute the MySQL part correctly :

Also, keystone returns and auth token when authenticating as "glance" :

I've tried reinstalling the glance package but I'm getting the same result. I'd apreciate if anyone would let me know what's going on - the --verbose and --debug options in glance aren't much help - in other words, I'm stuck and need assistance.
