The reverst of the problematic commit was reverted in mainline kernel. I have spent several days trying to understand the problem but unfortunately I don't have enough time to troubleshoot this more. I tried switching to virtio but for my use case of remote Linux desktops it is not usable. If I scroll a fullscreen web page I can see how the whole screen is redrawn every time, Meanwhile I've switched from SPICE to RDP. GNOME in trixie supports headless RDP sessions that make this very convenient. Client support is also much better for RDP. I solved the authentication problem by isolating each VM from each other on network level and then deployed rdpgw (https://github.com/bolkedebruin/rdpgw) in front of everything with OpenID authentication. -Timo
