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.

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

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  |

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

| 8d22d73b-508c-478b-8d32-b9eb24e1b7a3 | richo | ERROR  |          | cirros | m1.tiny |

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

• 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

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

| ID                                   | Name  | Status | Networks                   | Image  | Flavor  |

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
