Hi
After i am installing ovirt-guest-agent-common shutdown of a VM = takes about 90 seconds instead of 30 seconds without the agent. I am running on rhvm 4.1 build 4, host, engine and VM all are = rhel 7.3, agent version is ovirt-guest-agent-common-1.0.13-2.el7ev.noarch. Has anyone encounter this issue ?
This is pretty normal as there=E2=80=99s a timeout letting the = users logged in save their work etc. So the reboot is scheduled. This is not an issue, this is simply by design.
=20 @Vinzenz If there is no logged in user this should be as quick as = without the tool and I guess there isn't a user logged in @Guy? =20 Well, the definition of =E2=80=98Someone is logged in=E2=80=99 is = quite difficult to answer on linux machine. =20 Correct but if the system is doing nothing why would adding guest = agent is adding > 1 min to the shutdown? =20
The agent adds that, what it gets told to, it=E2=80=99s not hardcoded if = that is your point. =E2=80=9CIf the system is doing nothing=E2=80=9D is = again very subjective and not easy to answer. Anyway you=E2=80=99re welcome to change that delay if you insist. It=E2=80= =99s sent by the engine via the VM.shutdown verb on vdsm as the delay = parameter in seconds. Just I don=E2=80=99t support this change and I do see too many potential = pitfalls in trying to determine if we should skip the delay or not - As = I said, it=E2=80=99s a matter which is too subjective.
