     DROP DATABASE IF EXISTS nova_api;
     CREATE DATABASE nova_api;
     DROP DATABASE IF EXISTS nova_cell0;
     CREATE DATABASE nova_cell0;
     DROP DATABASE IF EXISTS placement;
     CREATE DATABASE placement;
     GRANT ALL PRIVILEGES ON nova.* TO \’nova\’@\’localhost\’ IDENTIFIED BY \’${NOVA_PASSWD}\’;
     GRANT ALL PRIVILEGES ON nova.* TO \’nova\’@\’%\’ IDENTIFIED BY \’${NOVA_PASSWD}\’;

to “host-passthrough” to use the host CPU model exactly;
to “custom” to use a named CPU model;
to “none” to not set any CPU model.
If virt_type=”kvm|qemu”, it will default to “host-model”,
otherwise it will default to “none”

(StrOpt) Set to a named libvirt CPU model
(see names listed in /usr/share/libvirt/cpu_map.xml).
Only has effect if cpu_mode=”custom” and virt_type=”kvm|qemu”
