Is euca-bundle-vol supported by Openstack with Keystone?

 I am using OpenStack that is as recent as mid-december 2011 version.
Glance is used to mange images.
Keystone is used for the authentication.
I want to save the image of a running instance.
I heard that "euca-bundle-vol" does the magic.
To run euca-bundle-vol, I need to provide euca-certificate, private key, euca user ID.
However, openrc file in the devstack tree does not have any entry to set those EUCA specific environment variables.
(Especially, EC2_USER_ID, EC2_PRIVATE_KEY, EC2_CERT.)

 Is euca-bundle-vol supported?

 Or, are there openstack APIs that save the image of a running instance and registers it to a new image?

 Here is my openrc file.
