Hi,

I seems very difficult to get this working. I have a Fedora 17 client, installed spice-xpi and tried to access console from User Portal but console never shows up. engine.log prints:

(window briefly flashes and disappeares again)
warning: could not fetch host certificate info cause used backend/sdk does not support it.

And have also used "spicec" directly from F17 client:
# spicec -h cirrus2-1.slu.se<http://cirrus2-1.slu.se> -p 5900 -s 5901 -w v36BkUumraDG (The first ticket had by this time expired, so this is a new one)
(flashes)

Warning: connect error 5 - need secured connection

I wrote a simple script that collects the parameter needed to for spicec
in case of secure connection, I was using it on RHEL6, it probably will
be easy to convert it to Fedora if it does not already work OTB:

#!/bin/bash

# Usage: ./spice_to_vm.sh host vm_name

PASSWORD="root_password_to_the_host"
SECONDS="1200"

ssh-copy-id root@$1 >& /dev/null

ID=`ssh root@$1 vdsClient -s 0 list table | awk '{print $1":"$3":"}' |
grep ":$2:" | sed -e 's/\:.*//g'`
ssh root@$1 vdsClient -s 0 setVmTicket $ID $PASSWORD $SECONDS keep >&
/dev/null

PORT=`ssh root@$1 vdsClient -s 0 getVmStats $ID | grep displaySecurePort
| awk '{print $3}'`
SUBJECT=`ssh root@$1 openssl x509 -noout -text -in
/etc/pki/vdsm/certs/vdsmcert.pem | grep Subject: | cut -f 10- -d " " |
sed -e 's/\ //g'`

scp root@$1:/etc/pki/vdsm/certs/cacert.pem /tmp/cacert.pem >& /dev/null
COMMAND="sudo /usr/libexec/spicec --host-subject \"$SUBJECT\" --password
$PASSWORD --secure-channels all -h $1 --secure-port $PORT --ca-file
/tmp/cacert.pem"

echo $COMMAND

Thank you so much, this helped me realize what the issue was. I had at first added the hosts to my engine with a "black" address on the storage network. But I changed the "display network" to the public network, so that you can connect to a console from anywhere. This made the certificate of the hosts invalid, as the "--host-subject" doesn´t match the address that you connect to:

# spicec --host-subject "O=slu,CN=cirrus2-2.sto.slu.se" --password RFesfeuIGHhd -h cirrus2-2.slu.se<http://cirrus2-2.slu.se> -s 5903

So this means that changing your display network breaks SPICE consoles. Less than good, I would say.

I was able to solve this by removing the hosts from engine and adding them again, but with the public address instead, so now the connection address and host subject match. I logged in to the admin portal, clicked for console and voilá, console appears. BUT if I log in to the user portal with the same credentials and click for console on the same guest(or any other), a console screen briefly flashes and then disappears:( Bug.

The engine is installed with SSL as enabled by default, the hosts too. VDSM and libvirt are all active and validate fine towards the engine; have status "UP" and so on, but can't get SPICE console working. VNC works of course, but SPICE would be much cooler:) How do I get console working with SPICE?
