Hi,
http://www.libvirt.org/html/libvirt-libvirt.html#virNodeInfo says that
memory size is in kilobytes, however when I use this call I get an
answer in Megabytes, see below. The hypervisor has 16 GB of RAM.

This is the python bindings bug. From the code:
http://libvirt.org/git/?p=libvirt.git;a=blob;f=python/libvirt-override.c;...
We are shifting the mem amount left 10 times (effectively divide it by
1024). Hence you'll get MB instead of KB. Although I am not quite sure
how to fix this. I see two options:
1) fix the code (possibly breaking other applications already relying on
the bug)
2) document it as known bug (not consistent with C struct)
