problem: glance image-list return error:
Unable to communicate with identity service: {“error”: {“message”: “The request you have made requires authentication.”, “code”: 401, “title”: “Not Authorized”}}. (HTTP 401)
solution: you can try
glance --os-tenant-name service --os-username glance --os-password your-password image-list
this is because you set environment variable to –os-tenant-name admin –os-username admin –os-password admin-password, while keystone create user glance to glance:service, so you must override those variable to generate valid request header.
You can use alias in your shell env, edit your ~/.bashrc file and add the following line:
alias glance='glance --os-tenant-name service --os-username glance --os-password your-password'
and export it to take effect: source ~/.bashrc
But if this is not help, something deep you should dig. Good luck.
horizon Volumes Internal Server Error
i set up cinder, and all cinder service is start/running, cinder-volumes vg is created. however, when i click the Volumes, it return internal server error. ?solution: i check /var/log/cinder/cinder-api.log, it says auth error. so i add user and service of cinder by keystone.
glance image-create Errno 111 Connection refused
solution: After you restart glance-*, please wait for seconds to run glance image-create commoand, or sometimes (in my case, it will case) it will cause the connection refused error. I think this is because the service is not completely finish, so your request will be refused.
pkg_resources.DistributionNotFound: python-keystoneclient==0.2.3.1.g3a3e254
solution: this is because the python_keystoneclient-0.2.3.2.g3ce7017.egg-info is installed but the keystone still require the old one. This will happen when you try to setup the new version and overwrite the old one.
linux-kernel-header-virtual
solution: apt-get install linux-headers-3.2.0-31-virtual, or you can use uname to get the version of linux, then install specific header virtual
