I don't think so, libxl_create_cpupool returns a new poolid for a newly
created pool, so they are not needed for that.
libxl_destroy_cpupool would only be used to delete a real cpupool, you
don't need dummy pools to remove pools.
BTW I noticed that we have libxl_list_pool vs
libxl_{create,destroy}_cpupool and
libxl_cpupool_{cpuadd,cpuremove,movedomain}. I think the interface
should use cpupool throughout and not just pool to make it clear what it
is a pool of. IOW libxl_list_pool should be libxl_list_cpupool, the type
should be called libxl_cpupool and functions such as
libxl_name_to_poolid should instead be libxl_name_to_cpupoolid.
Ian.
