Just to clarify, setting arbitrary resolution works through client <-> guest agent messages. When the guest has the capability (since RHEL7), spice-server reacts to that message, pass it along to QEMU which interrupts the guest' kernel with the resolution change. IIRC, windows guest agent is the one to set the resolution indeed. Either way, for both Win and Linux guests, the agent is needed indeed.

With all SPICE stuff properly installed, everything works out of the box: clipboard, resizing, file transfer from host to guest. With "properly installed" I mean: installed SPICE drivers manually from virtio-win ISO by loading them since the Windows installation beforehand, then once booted into Windows downloaded the vdagent ZIP from spice-space website and manually installed the service according to instructions. > >> > > >> > >> I'll check, maybe is not handled by driver but agent > >> > >> > As additional detail, in QEMU I use the option "-display spice-app", which automatically starts remote-viewer; though curiously it doesn't seem to create a virt-viewer directory inside ~/.config unlike when running remote-viewer manually... > >> > > >> > Thanks again. > >> > > >> > El vie, 14 oct 2022 a las 12:41, Frediano Ziglio (<freddy77@xxxxxxxxx>) escribió: > >> >> > >> >> Il giorno gio 13 ott 2022 alle ore 16:58 Carlos González > >> >> <piteccelaya@xxxxxxxxx> ha scritto: > >> >> > > >> >> > Hello. > >> >> > > >> >> > I'm trying a virtual machine with a live CD distribution called AntiX Linux, which is directly based on Debian. > >> >> > > >> >> > I'm using direct QEMU commands. > >> >> > In the VM configuration I have this for SPICE configuration: > >> >> > "-vga qxl -device virtio-serial-pci -spice unix=on,addr=path/to/vm_spice.socket,disable-ticketing=on -chardev spicevmc,id=spicechannel0,name=vdagent -device virtserialport,chardev=spicechannel0,name=com.redhat.spice.0 \" > >> >> > Then I boot the live ISO, double check that QXL driver is installed -which normally always is-, and install spice-vdagent package (version 20 here).
