Hello all,

I'm wondering what the pro's and cons of all the volume format types are ?
what are the (dis)advantages of any of the following ?
raw, bochs, cloop, cow, dmg, iso, qcow, qcow2, qed, vmdk, vpc

and what would be the pro's and con's to put a certain volume format
on a storage pool type ?
Directory pool, Filesystem pool, Logical volume pools, Disk volume pools, ?

For example :
raw volume format is highly portable, most virtualization solutions
support this type
nfs is simple to set up as a remote storage pool without huge
investments, but performance may not be optimal.
iscsi is slightly more complex than nfs but also cheap to set up and
when configured properly performs better.
lvm partitions are very usefull
Does an iscsi lun that is a raw partition on the target server
outperform an iscsi lun that is a file on a disk on the target server

Does anybody know a site that has a good comparison between the ones
mentioned above. (or some of them)
