Thanks for the info. From what I understand, if we are running less than Juno, the hw guest agent feature/fsfreeze is not fully functional even with the appropriate flags on the image.
I’ll keep an eye on the upcoming features before advertising this for the end users.

Any suggestions ? I could not find any documentation on how to do fsfreeze with QEMU GA other than the blueprints implementing the function.
