When an error status VM was deleted which a port belong to, The port can not be assigned to other VM again

[JianGang Weng]

In version liberty:
1. When you create an VM with a given logic port, for some problem(such as all of the neutron agents is offline), the instance fall to the error status.

2. Resolve the problems, and delete the error VM Instance.

3. Create an new VM with the old port, then you will find the port can't be assigned

@JianGang Weng:
Looks like an actual bug. I would expect that the port can be reused
after I delete the error'ed VM. Could you please attach a log to
show where in the code this happens?

I'm adding the Neutron tag as the root cause could be in the
nova<->neutron interaction.

sorry, the log of #3 is a new bug.

[Anusha Unnam (anusha-unnam)]

There is no patch submitted for this bug for more than 6 months, removing the assignee and setting the bug status back to confirmed.

[Anusha Unnam (anusha-unnam)]

This is not reproducible. I followed the same steps you mentioned and I didn't get port already in-use error. I was able to reuse the port. SO i think now this bug is invalid.

@JianGang Weng:
Sorry I didn't notice this is in liberty. I tried in current master and it worked well.
Is this bug still valid in liberty?

[Anusha Unnam (anusha-unnam)]

Since the reporter of this bug hasn't replied back, marking this bug as incomplete.
If you think this bug is still valid in liberty, please provide the logs for this bug from liberty and change the status.
