    A variety of answers to the fullscreeen conundrum, some of which are rather recent if you scroll downward sufficiently.

    Is Bookworm the VM client too? With GUI? Does this happen for all clients, just one, or one type?

    Off the top of my head, I think the scale always option may disappear if the guest display doesn't support it - I seem to recall VirtualBox Guest Additions being required for this functionality for some guests in VirtualBox (which I acknowledge you are
    not using, I'm just saying...) so I don't think it's "straightforward" functionality

    What video protocol are you using?

    I am most interested in installing Windows 10, as there computation

    I am most interested in installing Windows 10, as there computation

    problem is resent for Linux clients that I've installed.

    In

    virt-manager > Edit > Preferences > [console tab]

    I see options for

    Graphical console scaling [ Never / Fullscreen only / Always]
    Resize guest with window [System default / Off / On]

    This looks like it might just set defaults for options accessible from
    the VM view menu, but perhaps worth experimenting with?

    The only Linux VM I have in virt-manager used the spice display manager
    by default.

    If you are using spice too, this

    https://stackoverflow.com/questions/41990600/virt-manager-guest-resize-not-working

    suggests spice-guest-tools is required for Windows clients, with link
    to download page

    Does any of that help?

    Best wishes

    Just noticed the link you provided includes a ref to spice-guest-tools.

    With an Alpine client (and no "tools") I get less than optimal scaling from virt-manager - some black space at the horizontal edges, but there is a scaling of sorts going on, just not entirely using the available window space.

    Are you using the stock version of virt-manager?

    $ apt policy virt-manager
    virt-manager:
    Installed: 1:4.1.0-2
