For example, you can load a utility program called numactl. This means that you have to create the loop file (as shown above) or edit the data file at the end of the installation (which is even better and more portable) to make sure that it knows that you are using an NUMA node with more than one part. Such a number is not always available to it. Another known problem is that the installer needs to know the number of processors on the system. It will then assume that the disk is /dev/sda (most likely, the first hard disk on the system).
During the installation process, the program will not be able to find it. For some reason, the location of the virtual disk file on the DVD is actually stored in the file system, and not in the mounted filesystem thus, the filename is /dev/loop1.
