Comment #1 on issue 161 by [email protected]: Wrong calculation of free
memory using xen-pvm (2.4.2 under Gentoo)
http://code.google.com/p/ganeti/issues/detail?id=161
I believe you're mistaken as to how xen-pvm works. "free" shows the memory on dom0, but that is not from where the instance memory is taken. Take a look at xm info.
