Public bug reported:
Hi team,
I encounter this error in a lightly complicated situation:
OS : ubuntu
Branch : Icehouse
When booting a vm with admin role and assigning it with another tenant's
private network, it's fine to work.
But the update info cache action will started periodically, at this time, the
privous mentioned other tenant's
private network is filtered out from the function "get_available_network()"
if do not transfer the provisioned Non-None value net_ids parameter.
Then bad things happened as below:
The worst affect is the vm can not be deleted normally.
