Re: [Xen-users] Xen cLVM and iSCSI



Hi,

Unfortunately I don't have that level of control over the iSCSI partitioning.
(I buy the storage per LUN and I don't think the provider will like it
if I buy 100's of 10-100 GB LUNS)

Otherwise it would definitely be best as you would just devote a whole
"hd" to a VM.
