In addition to what Nicolás suggests you can also take inspiration from
how the "console" command is implemented in the "ovirt-engine-cli" tool:


https://github.com/oVirt/ovirt-engine-cli/blob/master/src/ovirtcli/command/console.py

That code shows how to obtain the required VM. Information (display
address, display port, etc). Then the virt-viewer configuration file is
created here:


https://github.com/oVirt/ovirt-engine-cli/blob/master/src/ovirtcli/platform/posix/spice.py

Note also that recent versions of the engine (including 3.6) can
generate the virt-viewer configutation file for you. For example, if you
know the id of the VM you can get the virt-viewer configuration file and
then launch the "remote-viewer" program with a simple script like this:

---8<---
#!/bin/bash -ex

# Connection parameters:
url="https://engine36.local/ovirt-engine/api"
user="admin at internal"
password="..."

# The identifier of the VM:
vm="3235367b-9bae-4ff1-87ed-b42446e97046"

# The name of the protocol, encoded in hexadecimal, it will
# be 5350494345 for SPICE and 564e43 for VNC:
protocol="5350494345"

# Download the "virt-viewer" configuration file:
curl \
--verbose \
--cacert /etc/pki/ovirt-engine/ca.pem \
--request GET \
--user "${user}:${password}" \
--header "Version: 3" \
--header "Accept: application/x-virt-viewer" \
--output "${vm}.vv" \
"${url}/vms/${vm}/graphicsconsoles/${protocol}"

# Launch the "virt-viewer" program (it will automatically delete
# the configuration file once loaded):
remote-viewer "${vm}.vv"
