[Starlingx-discuss] Is there any change to get SSH / Ping in VMs ?

[Sun, Austin]

Hi Ricardo:
     I don't think StarlingX change some openstack setting recently.
     is it enabling DPDK in system ?   could you check your duplex controller  free memory ?


Thanks.

Hello Team,

Currently I'm trying to launch a Cirros VM to perform the following operations (in a duplex config):

  *   Ping / ssh / scp

What I'm seeing is the following:

  *   I have created a security group with the following settings:

openstack security group create security1

openstack security group rule create --ingress --protocol icmp --remote-ip 0.0.0.0/0 security1

openstack security group rule create --ingress --protocol tcp --remote-ip 0.0.0.0/0 security1

openstack security group rule create --ingress --protocol udp --remote-ip 0.0.0.0/0 security1

  *   If I use any flavor with this property:
--property hw:mem_page_size=large


     *   I hit an error and the VM isn't launched:
controller-0:~# openstack server list
+--------------------------------------+-------+--------+----------+--------+---------+
| ID                                   | Name  | Status | Networks | Image  | Flavor  |
+--------------------------------------+-------+--------+----------+--------+---------+

+--------------------------------------+-------+--------+----------+--------+---------+

     *   However, if I use any flavor without the property mem_page_size I get a VM launched, with an IP, but I'm not able to ping it or ssh / scp to it, just login through virsh console.
controller-0:~# openstack server list, and there is no IP inside of the VM, please see below:
openstack server create --image cirros --flavor m1.tiny --network public-net0 --security-group security1 richo
+--------------------------------------+-------+--------+----------------------------+--------+---------+

$

With the latest changes is there anything that I'm missing to get this working ? even the "ip netns" command isn't giving me any value.

Thanks in advance
