2018-08-01 08:01:02 Rock_Zhao description For example: Theres compute Nodes: A and B and C instance "vmtest" runs on A now. Repreduce: 1.nova host-evacuate A 2.Assumed instance "vmtest" evacuated failed on B with libvirt error. And found the instance xml of vmtest is still in /etc/libvirt/qemu 3.Then try again "nova host-evacuate A".If vmtest is scheduled on B again, there will throw exception: Instance instance-vmtest already exists. Whether it should be clean up the instance xml of vmtest on the failed evacuated node B? Description =========== For example: Theres compute Nodes: A and B and C instance "vmtest" runs on A now. Steps to reproduce ================== 1.nova host-evacuate A 2.Assumed instance "vmtest" evacuated failed on B with libvirt error. And found the instance xml of vmtest is still in /etc/libvirt/qemu 3.Then try again "nova host-evacuate A".If vmtest is scheduled on B again, there will throw exception: Instance instance-vmtest already exists. Expected result =============== When vmtest first evacuated failed on B, remove instance xml of vmtest on B Actual result ============= If vmtest is scheduled on B again, there will throw exception: Instance instance-vmtest already exists. Whether it should be clean up the instance xml of vmtest on the failed evacuated node B? Environment =========== openstack mitaka
