it seems default enabling ovirt-guest-agent is dropped with tuned* stuff from rpm scripts:

- comparison between 1.0.14.1 an 10.0.14.2

 /sbin/udevadm trigger --subsystem-match="memory"
 
 /bin/systemctl daemon-reload
-
-TUNED_ADM=/usr/sbin/tuned-adm
-TUNED_PROFILE=virtual-guest
-if ! /bin/systemctl status tuned.service > /dev/null 2>&1; then
-    /bin/systemctl start tuned.service
-fi
-if (! $TUNED_ADM active > /dev/null 2>&1 || $TUNED_ADM active | \
-        grep -q "balanced$") && $TUNED_ADM list | grep -q $TUNED_PROFILE; then
-    $TUNED_ADM profile $TUNED_PROFILE
-fi
-if [ $1 -eq 1 ] ; then
-    /bin/systemctl enable ovirt-guest-agent.service
-fi
 preuninstall scriptlet (using /bin/sh):
 if [ "$1" -eq 0 ]
 then
