Thank you for the answer Gianluca, the windows vm is new, other linux vm don't have warning messages on the guest-agent. So the problem about shared folder is related to a bug on the old release of oVirt, if I understand.

On the VM (windows 10) i have installed: QEMU guest agent version 101.1.0 SPICE Guest Tools 0.141 Virtio-win-driver-installer version 0.1.185 UsbDk Runtime Libraries version 1.0.22 Spice webdavd 2.4 (64-bit) I can share the clipboard but can not mount a USB stick other than FAT-formatted or use a shared folder Is there a solution? oVirt as an upstream project cannot support every single release. Normally only the current one is under best (effort) support 4.2.1.7 released about 3 years ago. Any reason not to update in the mean time to a newer and better supported release? 4.3.0 has been released on February 2019 and is not supported any more, even if newer than yours. 4.4.0 has been released on May 2020 and now arrived at 4.4.4 I think that orange exclamation is there for a quite a long time... or did you update recently in any way from an older release and got it?
