2019-12-20 10:24:55 -0600 asked a question openstack over openstack external network

Hello there.

Hope you are fine.

I am deploying openstack using kolla on top another openstack platform.
lets name the two platforms OSLe0 and OSLe1: OSLe1 is the OpenStack platform installed on top of OSle0 instances.
my own architecture is a clustered control plane with network nodes separated of controller nodes.
my network nodes have interfaces on an OSLe0 subnet (extnet): this subnet is expected to OSLe1 external network.

My own problem resides on the external network of OSLe1 : basically an instance inside OSLe1 cannot ping the external network which is here the gateway of extnet's subnet.

I have tried to ping inside the namespace from a qrouter inside OSLe1 to this gateway but it fails.

the external network is created as type flat on OSLe1.

Do you have any idea on some points that i should take into account about external network in the case of OpenStack over OpenStack

Thank you.

I like the network design diagrams used in OpenStack, I would like to know which tool is used to make such diagrams.

2015-08-06 08:18:50 -0600 asked a question slow download from instances in Kilo release, 3 nodes version.

Hi everyone.
i need some help about slowness of wget from my instances. I have installed 3 nodes' KILO release of openstack on fedora 21 as described in the official documentation. everything is ok during the installation and verifications proposed at the docs.
right now i runned some instances based on fedora 22 cloud image .. but yum doesnot work correctly at the begining i thought it was a problem with repository but checked nothing appeared wrong then i choosed to download my rpm using wget but i noticed that it is too slow and if the file is just more than 10MB it interrupts before termnating download.
during the download by an instance form an external server I checked traffic im my external interface enp0s3 by tcpdump i see a lot of packets coming from external server of length 1420, in parallel with a tcpdump of router interface qg-xxxxxx i see one packet of length 1420 then a lot of packet with length 140 that come slowly then another packet of 1420 and so on.

on external interface enp0s3
-------------------------------------
external_serer.10361 > 10.0.2.103.50746 (my instance) :length 1420

on vRouter qg interface
--------------------------------
external_server.50280 > network.49281 : length 1420
network.ssh > 10.0.2.15.34502 : length 140


any help what could be the problem.

2015-04-29 13:02:28 -0600 commented question cirros instance cannot get ip address

to SGPJ : I assigned a static ip i am now able to ping only the router interface from the instance nothing else. to dbaxps : the state of private network port is ACTIVE but public network is DOWN unless if i remove the gateway and create a simple interface to PUBLIC, but with no port for floating ip
2015-04-29 10:46:04 -0600 asked a question cirros instance cannot get ip address

Hi i am working in an all-in-one VM openstack Juno, i launched the cirros instance (private ip 10.1.0.6) and associate to it a floating ip address (10.0.2.18)
My external network is 10.0.2.0/24
the private network is 10.1.0.0/24
a router between the two networks
from the log of the instance it seems like a dhcp problem as it tried to discover the ip address but in vain.
here is the log :

2015-04-28 09:58:27 -0600 asked a question error : network_type_value 'flat' not supported while creating a new external network

HI everyone,
i installed Openstack juno all-in-one in a single VM using the RDO packstack. i configured the external bridge to meet the configuration of my environment then i wanted to create the external network from the begining so i deleted the default network and also the router. when i tried to create a new external network i encounter the error : 

create failed (client error): Invalid input for operation: network_type value 'flat' not supported.

Hi everyone,
i follow the steps given by the official documentation of the Openstack Juno release, i am using fedora 20. everything is ok until the step of starting the openstack-nova-compute.service in the compute node it takes time to start then it fails. this question is already asked but i didn't found any appropriate answer for my case.

with this systemctl start openstack-nova-compute.service, i got :

Job for openstack-nova-compute.service failed. See 'systemctl status openstack-nova-compute.service' and 'journalctl -xn' for details.


here is the output of journalctl -xn.

i stopped the service and started to run again without any environment variables, it returns a connection problem

[root@controller etc]# keystone --os-username admin --os-password adminp --os-auth-url http://localhost:35357/v2.0 token-get Authorization Failed: Unable to establish connection to http://localhost:35357/v2.0/tokens

when i reply the commend with debug option, it retuns this: [root@controller etc]# keystone --os-username admin --os-password adminp --os-auth-url http://localhost:35357/v2.0 --debug token-get DEBUG:keystoneclient.session:REQ: curl -i -X POST http://localhost:35357/v2.0/tokens -H "Content-Type: application/json" -H "Accept: application/json" -H "User-Agent: python-keystoneclient" -d '{"auth": {"passwordCredentials": {"username": "admin", "password": "adminp"}}}' INFO:requests.packages.urllib3.connectionpool:Starting new HTTP connection (1): localhost Authorization Failed: Unable to establish connection to http://localhost:35357/v2.0/tokens

and nothing is added in the log file after running these commands.

Hi everyone i have a problem with keystone, I am istalling openstack following this tutorial https://github.com/ChaimaGhribi/OpenStack-Icehouse-Installation/blob/master/OpenStack-Icehouse-Installation.rst (https://github.com/ChaimaGhribi/OpenS...) when i enset the environment variables OS_SERVICE_TOKEN and OS_SERVICE_ENDPOINT and load the credential file admin_creds, then when i started the command keystone user-list or keystone token-get i got the error :

Authorization Failed: An unexpected error prevented the server from fulfilling your request. (HTTP 500)

here the configuration i have: in /etc/keystone/keystone.conf

[database]
connection = mysql://keystone:KEYSTONE_DBPASS@localhost/keystone

[DEFAULT]
admin_token=ADMIN
log_dir=/var/log/keystone

when i set the environment variables to 

OS_SERVICE_TOKEN=ADMIN
OS_SERVICE_ENDPOINT=http://controller:35357/v2.0

everything work but when i unset these variables and load the file

export OS_USERNAME=admin
export OS_PASSWORD=admin_pass
export OS_TENANT_NAME=admin
export OS_AUTH_URL=http://controller:35357/v2.0

then that error appears, can anyone help to know what is my problem ? here is the output of keystone debug
