Looking at some very sparse notes I made on the decision, I think what tipped the choice was that both qcow2 and lvm added overheads, but lvm was on the whole system i.e. the host has additional processing on every i/o whereas qcow2 overheads was only for guest i/o. More critically my note was the thought as well that it would be easier to move a qcow2 file to another machine/disk if necessary than to move a partition. _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
