Comment 2 for bug 1300364

400 bad request seems a client side issue. what version of glance client are you using?
could you please also post debug logs for the command with --debug option? so we are see the http interactions.
glance --debug image-create --name cirros --is-public true --container-format bare --disk-format qcow2 --location http://download.cirros-cloud.net/0.3.1/cirros-0.3.1-x86_64-disk.img
