I'm not concerned with performance.  The F32 installs took time too.  But it isn't as if
I was in a hurry.  These VM's are mostly only used to duplicate issues others are having
on the users list.  So, install time and user experience are irrelevant, to me.

I performed the above after assigning 1248mb and the install completed fine.

My suggestion would be that if the install process could detect/know that it is below the limits
needed it would notify the user and not proceed.  That is, not just crash.

Speed isn't the issue, for me.  It is crashing v.s. not crashing
