Description of problem:
the guest agent doesn't start, because ovirt-guest-agent.py is not exectuable

Version-Release number of selected component (if applicable):
ovirt-guest-agent/stable,now 1.0.10.2.dfsg-2 all [installed]

installed from official debian repo

How reproducible:
always

Steps to Reproduce:
1.
2.
3.

Actual results:
guest agent won't start

Expected results:
guest agent starts just fine

Additional info:
the systemd unit file calls /etc/init.d/ovirt-guest-agent start
on start which performs the following check:

bash -x /etc/init.d/ovirt-guest-agent start
+ PATH=/usr/local/sbin:/usr/local/bin:/sbin:/usr/sbin:/bin:/usr/bin
+ DESC='oVirt management agent'
+ NAME=ovirt-guest-agent
+ DAEMON=/usr/share/ovirt-guest-agent/ovirt-guest-agent.py
+ DAEMON_ARGS=
+ PIDFILE=/var/run/ovirt-guest-agent.pid
+ SCRIPTNAME=/etc/init.d/ovirt-guest-agent
+ '[' -x /usr/share/ovirt-guest-agent/ovirt-guest-agent.py ']'
+ exit 0

just add the executable bit and you are fine :-)

tested on debian 8.5 x64

PS: I hope this is not fixed in later versions, because this fix should really make it into debian stable, shouldn't it?

HTH
