Based on what described in bugzilla
https://bugzilla.redhat.com/show_bug.cgi?id=1697301
I created at the moment the file
/etc/ovirt-engine/engine.conf.d/99-ansible-playbook-timeout.conf
with
ANSIBLE_PLAYBOOK_EXEC_DEFAULT_TIMEOUT=80
and restarted the engine and the python script to verify

Just to see if it completes, even if in my case with a 30Gb preallocated
disk, the source problem is qemu-img convert command very slow in I/O.
It reads from iscsi multipath (2 paths) with 2x3MB/s and it writes on nfs
If I run a dd command from iscsi device mapper device to an nfs file I have
140MB/s rate that is what expected based on my storage array performances
and my network.

Not understood why the qemu-img command is so slow
The question still applies in case I have to do an appliance from a VM with
a very big disk, where the copy could potentially have an elapsed of more
that 30 minutes...
