The rest is filled in as the VM writes to it. raw can do sparse as well, but 1) virt-manager doesn't default to it if you choose raw which means it is allocating the full 20GB, and 2) even if you do choose sparse the semantics are a bit different for NFS, not sure if it affects your use case though: https://serverfault.com/questions/731632/does-nfs-and-smb-support-sparse-files - Cole _______________________________________________ virt-tools-list mailing list virt-tools-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/virt-tools-list
