I found two problems with my process. To use the local copy from the above Debian site, the image type must be fullvirt and the source must be local and not CDROM.
But it failed at a different point this time. While it was loading additional software I received two error messages:
/tmp/O0nBXJSb.iso.part could not be saved, because the source file could not be read. Try again later, or contact the server administrator.
There is not enough room on the disk to save /tmp/O0nBXJSb.iso.part. Remove unnecessary files from the disk and try again, or try saving in a different location.
The 'not enough room' may be coming from my selection of storage space. The default was 8 GB, but when I selected it, the system complained that there was only 2.1 GB available. So I change it to 2 GB. The is 1 GB of RAM set.
I have searched for the O0nBXjSB file with no luck so I don't know what can be increased to achieve more space for the vms. I have created 1 failed vm via the command line and 3 failed vms via virt machine manager. I do not know where there are stored or how to remove them to free up the associated space. Virtual Machine Manager has a delete function but I don't know the scope of it. I used it and found that the selections I made resulted in deleting the iso I used to install the associated vm (and other vms).
Here's:

How do I make space for the vms?
How might I better set-up/manage the disk space on this laptop?
Thanks in advance,
Ray
