Query-cpus-fast should serve the same purpose as query-cpus there, being less intrusive on the VM and allow to complete the deprecation process, if this is still wanted. If not, adding an option that lets hmp 'info cpus' call the old API doesn't seem unreasonable. > > Dave > >> Thanks, >> Sergio. > > -- > Dr. David Alan Gilbert / dgilbert@redhat.com / Manchester, UK > -- Kind Regards, Viktor
