I always used standard PS/2 mouse emulation and that was enough for me. + +Now, I bought two new monitors, instead of old one, and setup them as one logical monitor, using technology called Eyefinity - it's a part of standard Radeon software. Now Windows thinks, that I have one monitor with resolution 2160x1920 (I bought Dell monitors with a thin borders and use them in portrait mode). + +Windows uses it without any problems, but mouse become crazy - sometimes (~3 times from each 5) I can't move cursor to the right border of the screen, it looks like the invisible vertical border. I spent really huge amount of time to understand, which component is the root of problem and found, that it's really a mouse. I tried all possible variants (standard, tablet, virtio-mouse-pci, virtio-tablet-pci), and found, that in both mouse variants bug is reproducing, and in both tablet variants - cursor stuck near all real borders and corners, so it's not a variant too. +The only working variant becomes passing real USB port to my VM and insert second mouse to this port. So, now it's working, but I have two mice on my working place, which doesn't seems very useful. + +Here is my command line: + +QEMU_AUDIO_DRV=pa QEMU_PA_SAMPLES=4096 qemu-system-x86_64 -enable-kvm -M q35 -m 12168 -cpu host,kvm=off -smp 4,sockets=1,cores=4 \ +-bios /usr/share/qemu/bios.bin -rtc base=localtime -vga none -device secondary-vga \ +-drive id=virtiocd,if=none,format=raw,file=/home/akushsky/virtio-win-0.1.141.iso \ +-device driver=ide-cd,bus=ide.1,drive=virtiocd \ +-device ioh3420,bus=pcie.0,addr=1c.0,multifunction=on,port=1,chassis=1,id=root.1 \ +-device vfio-pci,host=05:00.0,bus=root.1,addr=00.0,multifunction=on,romfile=/opt/kvm/images/Sapphire.RX580.8192.170320_1.bin,x-vga=on \ +-device virtio-scsi-pci,id=scsi \ +-drive file=/dev/sdb,id=disk,format=raw,if=none,discard=on,cache=none,aio=native,detect-zeroes=unmap -device scsi-hd,drive=disk,id=scsi0 \ +-device ich9-intel-hda,bus=pcie.0,addr=1b.0,id=sound0 -device hda-duplex,id=sound0-codec0,bus=sound0.0,cad=0 \ +-usb -usbdevice host:046d:c52b + +All in all, I checked on Windows 7 and Windows 10, and on qemu 2.10 and 2.11 - bug is always reproducible. \ No newline at end of file |
