This sounds like a duplicate of bug 1648840 which was fixed and backported to stable/newton and release in 14.0.3: https://review.openstack.org/#/c/409706/ stable/mitaka is end of life upstream though so we don't have that patch in mitaka. Note that that change introduced a regression which was fixed by this backport: https://review.openstack.org/#/c/428671/ Which went into 14.0.4. ** This bug has been marked a duplicate of bug 1648840 libvirt driver leaves interface residue after failed start -- You received this bug notification because you are a member of Yahoo! Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1691850 Title: Nova doesn't cleanup port when instance launch fails due to virt issues Status in OpenStack Compute (nova): New Bug description: Description =========== Nova doesn't cleanup port when instance launch fails on a hypervisor due to virt issues, instance is automatically rescheduled to a different hypervisor which results in duplicate ports for the instance. Steps to reproduce ================== A chronological list of steps which will bring off the issue you noticed: * I booted a VM (openstack server create --image cirros --flavor m1.tiny --nic net-id=network-id test-vm) * then instance was scheduled on hypervisor h1 * then instance launch failed due to virt errors on h1 * then nova did not cleanup the port while cleaning up the failed instance * then instance was rescheduled on hypervisor h2 * then instance booted successfully * then I did openstack server list * then instance showed up with two IPs * then I did openstack port list * then there were two ports for the same instance Expected result =============== There should only be one port for an instance Actual result ============= There were two ports for the instance Environment =========== 1. Exact version of OpenStack you are running. openstack-nova-common.noarch 1:13.1.2-1.el7 openstack-nova-compute.noarch 1:13.1.2-1.el7 python-nova.noarch 1:13.1.2-1.el7 python2-novaclient.noarch 1:3.3.2-1.el7 2. Which hypervisor did you use? Libvirt + KVM libvirt.x86_64 1.2.17-13.el7_2.5 qemu-kvm.x86_64 10:1.5.3-105.el7_2.7 CentOS Linux release 7.2.1511 (Core) What's the version of that? 3. Which networking type did you use? neutron with OpenContrail Logs & Configs ============== Instance launch failure exceptions from the compute node:
