Hello Team,
Here are the details about issue
- Created VM via CLI 2-3 times everything went well
- Than tried creating 5 VMs from Horizon at a single time out of which 3 were Active and 2 failed with network ERROR
Error: Failed to perform requested operation on instance "yess-vm-6", the instance has an error status: Please try again later [Error: Build of instance 45dc7fee-22ab-432f-b05b-4c4e7598e7ed aborted: Failed to allocate the network(s), not rescheduling.].
Error: Failed to perform requested operation on instance "yess-vm-5", the instance has an error status: Please try again later [Error: Build of instance 17c777ef-c938-4e28-b5ed-0d556185f891 aborted: Failed to allocate the network(s), not rescheduling.].
- Than we tried combination nova configs in nova.conf of controller
~~~
[DEFAULT]/vif_plugging_timeout=900
[neutron]/timeout=30
~~~
~~~
[DEFAULT]/vif_plugging_timeout=300
[neutron]/timeout=60
~~~
- Than we created 10 VMs out of which 5 were Active and 5 in ERROR with same `neutron error`
- The reason behind why always compute-7 is selected it has weight in +ve value whereas for rest its in -ve
- The issues seems to be call/request timeout between nova and neutron
