I am creating a Centos 7 VM inside Proxmox 4.x with ZFS. I plan on using Ext4 or XFS for a file system in the Centos VM. When setting up the disks on Centos should I use "Standard Partition", "LVM" or "LVM Thin Provision"? I would not mind the ability to make the root partition bigger down the road if needed but its not essential.
