Open Stack

Hello guys,
I am fairly new to Openstack and am building a home lab to experiment with
it at my own pace.

Here's my present setup:

host/hypervisor: vmware workstation 10 (1 xeon 4 cores, 40 GB RAM)
os: Centos 7
openstack realease: Newton

Architecture is fairly simple:

1x Controller node (1 vcpu, 4 GB RAM)
1x Compute node (1   vcpu, 4 GB RAM)

After a couple of days of work I now have a working lab but am stuck not
being able to create and start basic cirros instance.

The issue has been confirmed using Horizon as well (instance creation fails
with same errors)


*root at controller1 nova]# openstack server create --flavor m1.nano --image
cirros --nic net-id=cd37f4c3-7860-4183-8901-deeb48448fe4 --security-group
default   --key-name mykey selfservice-instance*

root at controller1 ~]# openstack server list

*nova-scheduler.log*

Filter results: ['RetryFilter: (start: 1, end: 0)']

['RetryFilter: (start: 1, end: 0)']

As for the installation process I followed the openstack official
documentation at

*https://docs.openstack.org/newton/install-guide-rdo/index.html
<https://docs.openstack.org/newton/install-guide-rdo/index.html> *

After a bit of digging I've found that the instance had failed network setup

*/var/log/nova/nova-compute.log*

2018-03-05 11:35:08.939 20920 ERROR nova.compute.manager

bad15e4bc5714298b275e2f45ec8a6ff - - -] *Instance failed network setup
after 1 attempt(s)*

Up to this point I reviewed the whole configuration several time with a
special focus on nova<>neutron integration but at present I haven't been
able to figure out what is going on

Rabbitmq seems to work fine and communications between controller and
compute nodes work as expected (no logs to prove otherwise found).

Just in case here's the output of 'openstack network list' in case anyone
was wondering whether or not openstack had interfaces to play with.

I am using QEMU with KVM acceleration.

*[root at controller1 etc]# openstack network list*

Clues anyone ?

Thanks in advance

Cheers
Andrea
