Hello !

If you want to use all the features of Proxmox, including live migration 
and/or High Availability,
you should not use local storage (directory).

When you create a storage, you can choose iSCSI, Proxmox will manage the 
block storage.
After that, you can (and I think it's the best use case) create a LVM 
storage, based on the iSCSI storage.

Then, when you create your VM, it will use a logical volume of the LVM 
in the iSCSI LUN.
Theses LV can be seen from every proxmox nodes and Proxmox can manage 
which VM has access to which LV.
