Matt, you're right, allow me to correct myself below. Short: I still cannot reproduce it.
I just tested it below in a Single node DevStack with today's Nova git with the Nova instance being QEMU emulated, but I cannot reproduce the said failure in this bug description. Test environment ---------------- $ uname -r; rpm -q libvirt-daemon-kvm qemu-system-x86 4.0.0-0.rc5.git4.1.fc22.x86_64 libvirt-daemon-kvm-1.2.13-2.fc22.x86_64 qemu-system-x86-2.3.0-0.2.rc1.fc22.x86_64 I'm at these commits in my All-In-One DevStack environment: cinder: commit c7ca4b95b56539dd560dc88038ab994d50c8394d devstack: commit 72bdc8c27102db3b65651ded3a9944798238a2d4 glance: commit f84e49db5a455b36901b642125b5cf850f90c81d keystone: commit af568dd1afdcdc9ed7275a2824a2ca5ca50b004c neutron: commit 483de6313fab5913f9e68eb24afe65c36bd9b623 nova: commit 74ca660ab688e15ccd59ddfbfcdc9e1cecdc553d requirements: commit 56ab196ad1fb0e356d3fe0ec63e744ed10104a5d Test ---- $ nova flavor-show 1 +----------------------------+---------+ | Property | Value | +----------------------------+---------+ | OS-FLV-DISABLED:disabled | False | | OS-FLV-EXT-DATA:ephemeral | 0 | | disk | 1 | | extra_specs | {} | | id | 1 | | name | m1.tiny | | os-flavor-access:is_public | True | | ram | 512 | | rxtx_factor | 1.0 | | swap | | | vcpus | 1 | +----------------------------+---------+ Boot the instance: $ nova boot --config-drive false --flavor 1 \ --key_name oskey1 --image cirros-0.3.3-x86_64-disk cirrvm1 Nova instance's guest XML attached.
