amount of host 'setup'. If a guest is using iSCSI as its storage, then there is a step where the host has to login to the iSCSI target and create device nodes for the LUNs before the guest can be run. You don't want every single host to be logged into all your iSCSI targets all the time.
I am interested to know why you think this is a no-no. If you have a set of hosts and you want to be able to migrate between all of them and your shared storage is iSCSI why would it make a difference whether you had logged in or logged in on the migrate on each host? What about if the shared storage was Fibre Channel and it was zoned so that _all_ nodes saw the disk. Should you disconnect the block device when not in usage?
