Hi Vishy, While launching an instance if key-pair injection fails, still the instance comes up running. It is possible to change the administrator password for an instance by performing the 'changePassword' action, however the support is available in Xen but not in KVM. I am therefore inclined towards having the instance creation fail if key-pair injection fails.
