@Itamar - this is recurring problem, what about creating a wiki page for
it?

1) your command line is missing '--ca-file $CA_FILE' altoghether

2) you don't mention password

3) you shouldn't need to specify host subject at all because your host
(-h) matches name of server in CN field of host subject. If you override
it anyway, strip white spaces after commas in it:
--host-subject='C=US,O=ICL,CN=vm-srv'

4) you could omit -p and --secure-channels altogether in order to
achieve tls-only connection, but you can hit
https://bugzilla.redhat.com/show_bug.cgi?id=723582 then

So you should do (out of my head, may contain typos):
get CA:
* on engine, it is found here:
CA_FILE=/etc/pki/ovirt-engine/ca.pem
* on host, it's here:
CA_FILE=/etc/pki/vdsm/libvirt-spice/ca-cert.pem
* on any other host, get it from engine web interface:
wget -O ${CA_FILE} http://ovirt-engine.example.org/ca.crt

on the host, get UUID of the VM:
$ VM_UUID="$(ps -ef | grep ${VM_NAME} | sed -e 's/^.*-uuid[ \t]\+\([ \t]\+\)[ \t].*$/\1/')"

as root on the host, set ticket (password and its period of validity):
# vdsClient -s 0 setVmTicket ${VM_UUID} ${PASSWORD} ${VALIDITY_SECONDS}
(doing it via REST API is cleaner but more cumbersome for me)

if the hostname you're connecting does not match what is in CN field of
Subject of the server cert, get the subject without spaces after commas
on the host:
$ grep Subject: ${SERVER_CERT_FILE} | sed -e 's/^.*Subject:[ \t]*\(.*\)$/\1/;s/,[ \t]*/,/'

connect to the spice-server:
$ spicec --ca-file ${CA_FILE} -w ${PASSWORD} -h vm-srv -s ${SECURE_PORT}
OR, with newer, shinier and overall better client :)
# yum install virt-viewer
$ remote-viewer --spice-ca-file /etc/pki/ovirt-engine/ca.pem spice://vm-srv/?tls-port=${SECURE_PORT}
(you'll have to provide the password through the pop-up dialog)

if you need to provide host subject (host name/IP not matching the one from server cert Subject):
$ spicec --host-subject ${HOST_SUBJECT} [...]
OR
$ remote-viewer --spice-host-subject ${HOST_SUBJECT} [...]
