I tried with qemu-*kvm*-0.12.1.1, no memstats yet, but dynamically setting the 
amount of memory now doesn't work at all. I'll try to isolate the problem, I 
suspect it comes from qemu-kvm-0.12.1.1.

I can't use  qemu-0.12.1:

$ ./configure --enable-kvm --disable-xen                            
#error Missing KVM capability KVM_CAP_DESTROY_MEMORY_REGION_WORKS
      NOTE: To enable KVM support, update your kernel to 2.6.29+ or install   
recent kvm-kmod from http://sourceforge.net/projects/kvm.
