Fedora 21 iscsiadm errors (Could not insert module tcp.)

[Dan Prince]

When running Ironic on Fedora 21 I'm seeing the following iscsiadm deployment issue:

Mar 08 02:14:40 localhost.localdomain.localdomain ironic-conductor[11664]: Command: sudo ironic-rootwrap /etc/ironic/rootwrap.conf iscsiadm -m discovery -t st -p 192.0.2.14:3260
Mar 08 02:14:40 localhost.localdomain.localdomain ironic-conductor[11664]: Exit code: 12
Mar 08 02:14:40 localhost.localdomain.localdomain ironic-conductor[11664]: Stdout: u''
Mar 08 02:14:40 localhost.localdomain.localdomain ironic-conductor[11664]: Stderr: u"libkmod: kmod_module_insert_module: could not find module by name='iscsi_tcp'\niscsiadm: Could not insert module tcp. Kmod error -38\niscsiadm: iSCSI driver tcp is not loaded. Load the module then retry the command.\n\niscsiadm: Could not perform SendTargets discovery: iSCSI driver not found. Please make sure it is loaded, and retry the operation\n"

Running the same command manually gives similar results:

[root@localhost ~]# sudo ironic-rootwrap /etc/ironic/rootwrap.conf iscsiadm -m discovery -t st -p 192.0.2.14:3260
libkmod: kmod_module_insert_module: could not find module by name='iscsi_tcp'
iscsiadm: Could not insert module tcp. Kmod error -38
iscsiadm: iSCSI driver tcp is not loaded. Load the module then retry the command.

iscsiadm: Could not perform SendTargets discovery: iSCSI driver not found. Please make sure it is loaded, and retry the operation

    Install Fedora kernel-modules pkg for iscsi_tcp

    The newest stable Fedora splits out kernel modules into
    a separate package. By default this is not installed in
    the Fedora cloud image... and it contains some things we
    need for Ironic (iscsi_tcp module) among other things that
    might be very useful.
