I know that some virtualisation have possibility to do > dynamic slices(4 example Virtul box) Do you mean storage overcommit? That is, assign more storage to domU than what you actually have? If yes, it's not a matter of Xen vs VirtualBox. It's a matter of what storage backend you use. If you use one of these: - sparse raw file (with file: or tap:aio:) - qcow - vmdk/vdisk (I think full support is only in newer Xen or Opensolaris) - zvol (on Opensolaris) then you can overcommit storage. But if you use disk/partition/LVM for domU storage, you won't be able to. -- Fajar _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
