Open Stack

Hi Martin,

the directory needs to be owned by the nova user so it can create and remove directories. Take the permissions in /var/lib/nova as an example and replicate that to your desired directory. 

Personally I wouldn't put the instance path into /home more into a subdirectory of home (something like /home/nova)

I have enabled debug=true in the nova.conf and this is the error i am getting

Error: Failed to launch instance "test": Please try again later [Error: No valid host was found. ].   on THE HORIZON DASHBOARD

2015-04-20 09:32:43.681 3396 TRACE nova.compute.manager [instance: 7eb2a694-a256-43d6-89bf-ee6126be0b17] OSError: [Errno 13] Permission denied: '/home/7eb2a694-a256-43d6-89bf-ee6126be0b17'  --- on nova.conf

and this error when launching a test instance happened when i changed the instance path to /home .... tried changing permissions and its still the same

Hi Martin,

you can find some clues in nova.log,you can also try to enable debug log in nova.conf ( debug = True)

I have hit another wall ,i think its a result of my changing the instance_path to /home in the /etc/nova/nova.conf

Error: Failed to launch instance "test": Please try again later [Error: No valid host was found. ].

still checking the doc you sent me but just thought while i research on my own the mailing list will have something on the fingertips

I just installed openstack and im still learning everything I can get my
hands on , from youtube videos to openstack docs and just thought I can join
a mailing list to speed up the process of acquiring openstack knowledge.

This is my case : I have openstack all_in_one and right now everthing is
just on one machine [from reading the docs seems like I can expand my
openstack projects [cinder ,nova etc] to other nodes and that will be for
later]

Right now I have installed the RDO icehouse packstack and its on a centos
machine , with 4 gig. So far so good.On the same machine I have configured a
/home directory with 1 terabyte for storing my images and when I open
openstack dashboard , I cant seem to find a way to reference it ,how can I
add that filesystem as my storage for my VMs

My filestystem is as follows

[root at cumulonimbus ~]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/vg_cumulonimbus-lv_root
-------------------------------------------on open stack dashboard ,it seems
to recognize this only

Sounds like you're looking for instances path?  In other words the location you want the qcow files for the instances to live?

That's set up in the nova.conf file as: instances_path

Check out the docs page here and see if that helps.  Items like conf settings don't show up in the dashboard by the way.

Thanks,
John

thank you john , managed to read the doc you sent me and what i wanted seem to have worked ,let me get my hands dirty on youtube videos and any docs that can help me before i scale out my all_in one packstack
