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
