failed to start VM in multi-node environment

Hello

Due to some errors in selective distribution I decided to disable this feautee and continue running the tests to start VMs.

I am running 2 nodes environment.
I executed the following commands:

cd ~/devstack
source ./openrc admin demo
nova boot --flavor m1.tiny --image cirros-0.3.4-x86_64-uec --nic net-name=private --security-group default test2

After some time I am getting an error in "nova list" command:
+--------------------------------------+-------+--------+------------+-------------+-------------------------------------------------------+
| ID | Name | Status | Task State | Power State | Networks |
+--------------------------------------+-------+--------+------------+-------------+-------------------------------------------------------+
| 318dc00b-09a6-4758-9193-fa078cdb23ce | test2 | ERROR | - | NOSTATE | |

When checking the staatus of VM i see an error message:
{"message": "Build of instance 318dc00b-09a6-4758-9193-fa078cdb23ce aborted: Failed to allocate the network(s), not rescheduling.", "code": 500, "details": " File \"/opt/stack/nova/nova/compute/manager.py\", line 1779, in _do_build_and_run_instance
