Hi All, I've just had a little check on a hyper-visor (based on Centos 6.3) VDSM versions: vdsm.x86_64 4.10.0-0.44.14.el6 vdsm-cli.noarch 4.10.0-0.44.14.el6 vdsm-python.x86_64 4.10.0-0.44.14.el6 vdsm-xmlrpc.noarch 4.10.0-0.44.14.el6 BUT - my concern is more that a VMs virtual memory (VSZ) allocation is much higher than that of its configuration ? qemu 24233 11.0 1.0 *3030420* 1008484 ?
