Hi Roberto,
we already opened a bug on it:
https://bugzilla.redhat.com/show_bug.cgi?id=1352601
and we already have a fix: https://gerrit.ovirt.org/#/c/60142/

The fix will come with the next release but it's really simple:
if you are brave enough you could simply edit
/usr/share/ovirt-hosted-engine-setup/plugins/gr-he-setup/storage/blockd.py
on your host replacing 'devList' with 'items' in line 407.
