Hi. I was expecting that qemu-kvm process would connect directly to iSCSI server, but https://libvirt.org/storage.html#StorageBackendISCSI says that it wants symlinks in `/dev/disk/by-path` . That suggests it relies on Linux iSCSI client that will act as mediator and create block devices. So is "iSCSI volume pools" just a convenience thing giving no performance gain compared to attaching block devices to my guest?
