I think, this is an issue of the Redhat Xen installer(I assume you are
not trying to manually run anaconda somehow but use virt-install), not
Xen in general.

Why?
1) this problem never occured to me with xen-tools on Debian and Yast on
SuSE

2) Sure, a user has always the chance to make wrong settings and break
stuff, but in your case, the writers of the Redhat Xen install scripts
should know how much memory is needed by their anaconda.

So, it is undoubtedly easy to check for them at the very start, and at
least give out a visible warning that you try to run the stuff with not
enough memory, instead of let you run into a strange blocking state.
( In case I missed you writing you found the fix through such a warning,
I admit you that point!)
