I have hundreds of Xen-based virtual machines running off a ZFS/iSCSI
service; yes, it's viable. I can't speak for CentOS specifically; our
infrastructure is using Debian Etch with our own build of Xen.

How does ZFS handle snapshots of large files like VM images? Is
replication done on the bit/block level or by file? In otherwords, does
a snapshot of a changed VM image take up the same amount of space as the
image or only the amount of space of the bits that have changed within
the

I had originally considered something similar, but... for ZFS snapshot

(FreeBSD, for example) can install onto NFS, it wouldn't actually be going
over the network, and it would allow file-level restore instead of
