I've got a couple of VMs giving me this error message, "the latest guest agent needs to be installed and running". These VMs have the latest guest agent installed and it is running (virtio-win-1.9.24.iso) The only change to the environment recently was one host has been upgraded from 4.5.2 to 4.5.3. It seems to be the VMs that had at one point ran on this updated host. However, that host is currently turned off they are running on 4.5.2 hosts and have been rebooted. These are Windows Server 2022, 2019 and Windows 11 VMs. I will be updating the rest of the hosts this weekend so can see what happens then. The qemu-guest-agent tools is the same version running elsewhere even tried to repair it no change. Any ideas? Cheers, Chris.
