Description of problem:
There are two failures that are in need of extra eyes:
A) https://rhos-qe-jenkins.rhev-ci-vms.eng.rdu2.redhat.com/view/ReleaseDelivery/view/OSP15/job/phase2-15_director-rhel-8.0-virthost-3cont_2comp-ipv4-gre-lvm/lastCompletedBuild/testReport/tempest.api.compute.servers.test_server_actions/ServerActionsTestJSON/test_resize_server_revert_id_c03aab19_adb1_44f5_917d_c419577e9e68_/

B) https://rhos-qe-jenkins.rhev-ci-vms.eng.rdu2.redhat.com/view/ReleaseDelivery/view/OSP15/job/phase2-15_director-rhel-8.0-virthost-3cont_2comp-ipv4-gre-lvm/lastCompletedBuild/testReport/tempest.api.compute.servers.test_server_actions/ServerActionsTestJSON/test_resize_server_revert_with_volume_attached_id_fbbf075f_a812_4022_bc5c_ccb8047eef12_volume_/

Build logs for both failing tests are here: https://rhos-qe-jenkins.rhev-ci-vms.eng.rdu2.redhat.com/view/ReleaseDelivery/view/OSP15/job/phase2-15_director-rhel-8.0-virthost-3cont_2comp-ipv4-gre-lvm/lastCompletedBuild/artifact/


It seems that both operations did not finish within 300 seconds:
