[kaitian521]

I use Havana openstack, and after installing all the modules, i use :nova boot --image XXX --flavor 1 instance_name" , BUT the instance come to ERROR state. I looked up the compute.log,

ERROR is :

    "%(unit)s") % locals()

WHEN I comment the line out , boot can be active.

    msg = _("%(type_)s limit: %(limit)d %(unit)s, free: %(free)d %(unit)s") % locals()

BY THE WAY, when I change it to

    msg = _("%(type_)s limit: %(limit)f %(unit)s, free: %(free)f %(unit)s") % locals()

nova boot can success also, "limit" may be a float instead of a integer.

Thank you

    Fix format error in claims.

    I have now seen two bug reports today about log message formatting
    in the claims code. I'm not 100% sure what's going on here, but
    I've removed the use of locals() in the hope it makes it clearer.
    I've also moved to treating limits as floats because I think it
    makes the messages clearer, but it is not a functional change.

    Resolves bug 1175923.
