Hi, we are currently preparing our Windows software packages for update oVirt from version 4.3 to version 4.4. One of the novelties[1] of version 4.4 is the change from the ovirt-guest-tools to the virtio-win guest tools. We are currently running version 4.3.9.4-1.el7 in our oVirt cluster. When we are installing the new virtio-win guest tools we get the tooltip message: "Actual timezone in the guest differs from the configuration". The guest agents of the two guest tools are completely different, the ovirt-guest-agent is written in Python, the qemu-guest-agent is written in C. So my guess was, that there would different result send to the ovirt-engine. As I looked into the sources of ovirt-engine, especially into the timezone Java stuff, I did not found any changes in the last few months. So is this bug fixed, with the new ovirt version 4.4, or is this aspect new? P.S. The os in the vm was Windows 10 version 1909 [1] <https://ovirt.org/release/4.4.0/> Best Regards Tobias Scheinert
