Following up, when I attempt to launch a medium flavor image, here's the output in the nova scheduler log file:

"openstack@lists.openstack.org<mailto:openstack@lists.openstack.org>" <openstack@lists.openstack.org<mailto:openstack@lists.openstack.org>> Subject: [nova] No valid host found Hi everyone, Whenever I try to launch an image instance beyond 'micro' (anything that has more than 0 GB disk space) I get the "no valid host found" error, even though my disk has 100+ GB of space, even displayed in the dashboard. The error in the nova scheduler says "Flavor's disk is too small for requested image." Any suggestions as to what I should try or what may be happening? FYI I'm running a DevStack based install of OpenStack. Thanks, Mark
