64-bit, default graphical anaconda.

At 250MB it's obviously page-thrashing.  Testing to see if it actually
finishes is drudgery, yet it's important to observe the details
of any failure.

The motivation for such low memory is old laptops (thus subtracting
a couple MB for video frame buffer in main RAM) and old servers, or
perhaps new virtualized servers.
