On the Linux kernel, if huge pages are allocated the size they cut off from memory is accounted under the 'MemUsed' in the meminfo file. However, we want the sum to be subtracted from 'MemTotal'. This patch implements this feature. After this change, we can enable reporting of the ordinary system pages in the capability XML: <capabilities> <host> <uuid>01281cda-f352-cb11-a9db-e905fe22010c</uuid> <cpu> <arch>x86_64</arch> <model>Haswell</model> <vendor>Intel</vendor> <topology sockets='1' cores='1' threads='1'/> <feature/> <pages unit='KiB' size='4'/> <pages unit='KiB' size='2048'/> <pages unit='KiB' size='1048576'/> </cpu> <power_management/> <migration_features/> <topology> <cells num='4'> <cell id='0'> <memory unit='KiB'>4048248</memory> <pages unit='KiB' size='4'>748382</pages> <pages unit='KiB' size='2048'>3</pages> <pages unit='KiB' size='1048576'>1</pages> <distances/> <cpus num='1'> <cpu id='0' socket_id='0' core_id='0' siblings='0'/> </cpus> </cell> ... </cells> </topology> </host> </capabilities> You can see the beautiful thing about this: if you sum up all the <pages/> you'll get <memory/>.

LibVirt : simple API for virtualization Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes). It is free software available under the GNU Lesser General Public License. Virtualization of the Linux Operating System means the ability to run multiple instances of Operating Systems concurrently on a single hardware system where the basic resources are driven by a Linux instance. The library aim at providing long term stable C API initially for the Xen paravirtualization but should be able to integrate other virtualization mechanisms if needed.
