That would be nice. If you happen to have time to put something like
"3*nrdomains_diff+memfree_diff" and see how it goes, I'll be happy to
include at least that change, even in next posting.

I did that. Guests are 2 VCPUs/2GB RAM.


The results looked much better.

That's very good to hear. :-)


So without any deeper thinking this looks much better than the original
version and possibly good enough for Xen 4.2.
Maybe the automated testing finds some leftovers.

So, here's what we can do:

  1) I can resend the series with this change in it (i.e., number of
    domains weighting 3 times more than free memory);

  2) I can resend the series like in 1) _but_ while also converting the
    domain counting in vcpu counting (I checked that and it's trivial);

  3) I can resend the series like in 1) and also send a separate patch
    turning the domain counting in vcpu counting, and we can apply that
    after it get some testing;

Which one you like better?

I'd prefer 2). To me it makes more sense and I can test it over the weekend and can send my acked-by on it.
