Hi to all! I can't use the after_xxxx hooks in the guest agent (version: 1.0.16-1.el7) installed in a centos 7 machine in a ovirt 4.3 cluster, but the before_xxxxx hooks are executed without problem The same machine in an old ovirt cluster was ok with the same hooks. This is the ovirt-guest-agent.log MainThread::INFO::2019-06-18 13:15:11,192::ovirt-guest-agent::59::root::Starting oVirt guest agent Dummy-2::INFO::2019-06-18 13:15:11,326::OVirtAgentLogic::322::root::Received an external command: refresh...

Dummy-2::INFO::2019-06-18 13:18:24,605::OVirtAgentLogic::322::root::Received an external command: api-version... As you can see, the agent does not receive the lifecycle-event for after-migration I look in the vdsm and supervdsm log, also in debug level, but seem all normal the xml of the machine contain the virtio-serial <controller index="0" ports="16" type="virtio-serial"> <alias name="ua-9785547d-0e2d-4139-8952-010fe4874800"/> <address bus="0x00" domain="0x0000" function="0x0" slot="0x06" type="pci"/> </controller> . . . . . <channel type="unix"> <source mode="bind" path="/var/lib/libvirt/qemu/channels/27f3d4d0-f3d2-41bf-a8da-e6e75aad51f6.ovirt-guest-agent.0"/> <target name="ovirt-guest-agent.0" state="connected" type="virtio"/> <alias name="channel0"/> <address bus="0" controller="0" port="1" type="virtio-serial"/> </channel> <channel type="unix"> <source mode="bind" path="/var/lib/libvirt/qemu/channels/27f3d4d0-f3d2-41bf-a8da-e6e75aad51f6.org.qemu.guest_agent.0"/> <target name="org.qemu.guest_agent.0" state="connected" type="virtio"/> <alias name="channel1"/> <address bus="0" controller="0" port="2" type="virtio-serial"/> </channel> I tried also with another 2 machines with a fresh install of centos 7 and guest-agent but nothing. The guest agent does not have any error in systemctl status ovirt-guest-agent This is my hook in /etc/ovirt-guest-agent/hooks.d/after_migration -rwxrwxrwx. 1 root root 34 Jun 14 12:48 01_example and this is the content: #!/bin/bash touch /tmp/prova this script in before_xxxx start without problems Someone have some suggestion or some log to see to solve this problem? Thank you!
