I see the same thing with a new 3.5-beta install.  libvirtd is running;
I ran the above vdsm-tool command, but that made no difference.

The libvirtd.conf has the following config (set by vdsm install):

## beginning of configuration section by vdsm-4.13.0
keepalive_interval=-1
log_outputs="1:file:/var/log/libvirt/libvirtd.log"
unix_sock_rw_perms="0770"
auth_unix_rw="sasl"
log_filters="3:virobject 3:virfile 2:virnetlink 3:cgroup 3:event 3:json 1:libvirt 1:util 1:qemu"
cert_file="/etc/pki/vdsm/certs/vdsmcert.pem"
unix_sock_group="qemu"
listen_addr="0.0.0.0"
ca_file="/etc/pki/vdsm/certs/cacert.pem"
key_file="/etc/pki/vdsm/keys/vdsmkey.pem"
host_uuid="74e1d154-d83f-4852-9c35-3c931f8b45cf"
## end of configuration section by vdsm-4.13.0

If I comment out the auth_unix_rw line and restart libvirtd, vdsmd will
start successfully.
