[libvirt-users] Can libvird use iSCSI direcly?
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?

Correct, iscsi pools are just a wrapper around mounting iscsi on your host. That said, libvirt via qemu supports directly connecting to iscsi as well, configured via the VM XML. Search for protocol='iscsi' in https://libvirt.org/formatdomain.html - Cole
