Hi, with a guest set up as in the following example mouse behavior breaks: <graphics type='spice' port='5901' autoport='no' listen='0.0.0.0'> <listen type='address' address='0.0.0.0'/> <gl enable='no'/> </graphics> <video> <model type='qxl' ram='65536' vram='16384' vgamem='16384' heads='1' primary='yes'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x0'/> </video> <video> <model type='qxl' ram='65536' vram='16384' vgamem='16384' heads='1'/> <address type='pci' domain='0x0000' bus='0x08' slot='0x01' function='0x0'/> </video> Please note that this is for illustration purposes as this everyone can easily retry. I originally had QXL + GPU as mediated device, where the behavior is the same. If I know connect to that via spice, spice is smart and opens both displays: $ virt-viewer --connect qemu+ssh://ubuntu@10.246.115.255/system guestname But while with one display mouse integration (to move in/out smoothly) and positioning of the mouse pointer is fine. It is broken with this double display setup. What I see is: - no mouse integration anymore (falls back to capture the mouse) - often the mouse can not move upwards anymore - sometimes "left" also doesn't work Let me know if someone wants a video in case the description is still too odd. I have tried spice-client-gtk and virt-viewer, but both behave the same way. If I take away one of the displays it works well again. So I'm wondering how virtual-multi-monitor is supposed to work, are there known bugs or tweaks that would apply here? In my original case I wanted to take away the QXL device, to jst keep the Mdev as one screen (and the one I really want). But due to [1] the video section is re-added automatically. Maybe this comes down to not re-adding that default video entry if a hostdev has display=on set? I'd appreciate any pointers if this rings a bell or a discussion on not-auto-adding-video if display=on is present. Kind Regards, Christian P.S. I tried VNC but that just has "other" issues. It only shows 1 of 2 displays and on the one I see over amplifies the mouse movement by the amount the other display adds to ther overall desktop size. P.P.S. Sorry for cross posting, at least I avoided cross posting even further (spice-devel / qemu-devel) hoping that libvirt & virt-tools would be involved enough that if someone recognizes this he can point me to the right place.
