2017-11-08 01:53:02 -0500 answered a question how to create Neutron subnet

Subnet pools are an advanced feature. What you need is a CIDR - not a subnet pool. Try the following:

openstack subnet create --allocation-pool start=192.168.199.2,end=192.168.199.254 --network test1 --subnet-range 192.168.199.0/24 test_sub

allocation_pool must be an subset of the CIDR (i.e. 192.168.199.0/24).

2017-11-04 08:00:13 -0500 answered a question how to ssh in Openstack to 2 instances by same Key-Pair

If all instances are in the same private network the default security group allows any traffic. You must, however, copy the private ssh key to all the instances and store them in .ssh/id_rsa. Then ssh should work between the instances, too.

Enable the user liadolin01 and try again. See above.

First enable the user liadolin01 and then try again. In the first screen and in the logging we see that this user is disabled.

2017-09-13 11:18:24 -0500 answered a question Where is the MAC pool defined for OpenStack instances?

See the configuration settings base_mac and dvr_base_mac in neutron.conf. Documentation: https://docs.openstack.org/neutron/pike/configuration/neutron.html (https://docs.openstack.org/neutron/pi...)

2017-09-11 08:48:41 -0500 commented answer unable to create the container

An OpenStack user must have the swiftoperator or admin role in order to launch the swift stat command or the equivalent in the dashboard. Please verify that.

2017-09-11 08:37:02 -0500 commented question Nova - unable to attach encrypted volume

Did you set up keys in /etc/nova/nova.conf and /etc/cinder/cinder.conf in the key manager? See fixed_key in [keymgr].

2017-07-06 09:43:46 -0500 commented question what's role for service user on keystone?

did you read the help text from: keystone-manage bootstrap --help ? The keystone user and its role are passed as parameters to this command.

2017-07-05 03:21:46 -0500 commented question After I reboot the controllers node, the rabbitmq web can not access now.

I have a similar problem with rabbitmq. I tried the following setting: ListenStream=0.0.0.0:4369 in a systemd drop-in in /etc/systemd/system/epmd.socket.d, but this only alleviates the problem (rabbitmq-plugins still does not work). I try a single controller installation with Newton.

2017-05-11 10:42:26 -0500 commented answer Nested virtualization with KVM/OpenVSwitch

Let me repeat my previous question in another way. It does not make sense to define a single switch port (vnet8) as a VLAN trunk and all other ports as native VLANs. 2003 and 2004 need to be defined for other ports too. Did I miss something?

2017-05-10 09:50:58 -0500 commented answer Nested virtualization with KVM/OpenVSwitch

I do not understand why dev dev1 on databr0 is not a VLAN trunk with IDs 2003 and 2004? The traffic from vnet8 does not go to anywhere.

2017-05-10 04:21:07 -0500 commented answer Nested virtualization with KVM/OpenVSwitch

I have done a similar installation for a 'virtualized' SUSE OpenStack Cloud. The difference to what I see in your setting, is that I used portgroups in openvswitch for each of the node types in OpenStack (compute, controller, storage etc). I do not see any VLANs in your xml.

2017-05-07 14:38:35 -0500 answered a question Nested virtualization with KVM/OpenVSwitch

An instance usually gets its IP address assigned by DHCP. In your installation, what is the configuration of the network within KVM? Would you show us the output of virsh net-dumpxml?

2017-05-07 14:38:35 -0500 answered a question How does neutron choose subnet

If you have defined several subnets in a single network you may choose the subnet a port is created in. The syntax is: openstack port create --network <network> --fixed-ip subnet=<subnet> <port-name>. If you do not choose a subnet, I do not know what subnet Neutron chooses. (Newton release)
