http://unix.stackexchange.com – I am setting up a machine to run a number of virtual machines. I am using a single HDD with a boot partition and an LVM partition. I read on the Arch wiki that logcial volumes which will be used for swap should be setup with -C y To create a contiguous partition, which means that your swap space does not get partitioned over one or more disks nor over non-contiguous physical extents. How important is this? If i have a dozen VMs each with a contiguous logical volume for swap and a non-contiguous logical volume for /, how will having so many contiguous logical volumes affect my abilit (HowTos)
