      Hmm. If you remove the qemu-agent can I assume this goes away?

        When I stopped qemu-ga service zombie processes died.
        I have checked it several times. But I need qemu-ga in my oVirt installation.

          Hmm, well can you configure it not to query the disk status? I would assume that also solves it.

          Can you test qemu-agent in a FreeBSD 12.3 install? Hard to see what but it might be something in base that's changed.

            I am trying to disable query for file system status in qemu-ga.

              With this parameters -d -v -l /var/log/qemu-ga.log -b "guest-get-fsinfo" qemu-ga does not generate zombies.
              -b "guest-get-fsinfo" - means - blacklist guest-get-fsinfo command

                Mmm, OK. And does that still provide the info you need?

                  qemu-ga provides information about interfaces, logged in users and fqdn. I cant see information about guest agent version, OS, timezone, architecture and file systems (i have disabled file system info by myself).

                    And that's sufficient?

                      I would like to get all info from qemu-ga. Like from Linux VM.
                      FreeBSD qemu-ga has strange behavior - in default config (when -m is not present) I see method - isa-serial. But in VM config - virtio-serial. And when I set virtio-serial in qemu-ga config, qemu-ga can't get any request from oVirt.

                      qemu-ga -d -v -l /var/log/qemu-ga.log -m virtio-serial - does not work
                      qemu-ga -d -v -l /var/log/qemu-ga.log - works with some restrictions in info

                        Ok, the next thing I would test here is whether it works as expected in FreeBSD 12.3.
                        Is this an upstream regression or something we are doing in pfSense specifically.

                          Today I will try FreeBSD 12 on ovirt.
                          There is qcow image on download.freebsd.org
                          I will try clear iso and qcow image.

                              Hmm, so something different about our filesystem perhaps?

                              Permissions issue?

                              Same qemu-agent version?

                              There can't be much different there.

                                On FreeBSD 12.3 - qemu-ga -V
                                QEMU Guest Agent 5.0.1

                                On pfSense - qemu-ga -V
                                QEMU Guest Agent 5.0.1

                                Command line on FreeBSD - qemu-ga -m virtio-serial -d -v -l /var/log/qemu-ga.log

                                Command line on pfSense - /usr/local/bin/qemu-ga -d -v -l /var/log/qemu-ga.log -b guest-get-fsinfo

                                  In FreeBSD I have run /usr/local/bin/qemu-ga -d -v -l /var/log/qemu-ga.log -b guest-get-fsinfo.
                                  And everything works fine.

                                      Ok, lets get a bug report open to track this.

                                      What steps are required to replicate this?

                                        I have installed pfSense 2.5 from ISO on virtual machine in oVirt 4.4.5, then I have upgraded it to 2.6 from WEB interface. Then I added qemu-guest agent using this instruction - https://forum.netgate.com/topic/162083/pfsense-vm-on-proxmox-qemu-agent-installation
                                        And got the problem, described above.
