RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Comment 3 Peixiu Hou 2019-12-13 10:05:26 UTC
Hi Yuri,

I cannot reproduce it with our lab used mouse device, just connect it to vm, maybe my steps has some problem, so could you help provide some simple reproduce steps to reproduce it?

I used command as:
    -enable-kvm \
    -device virtio-mouse-pci,id=input_input1,bus=pcie.0,addr=0x5 \
    -monitor stdio -qmp tcp:0:5888,server,nowait \
    -vga qxl \
    -spice port=3001,disable-ticketing -soundhw hda \
    -device virtio-serial,bus=pcie.0 -chardev spicevmc,id=vdagent,debug=0,name=vdagent \


Thanks a lot~

The problem happens with vioinput

The repro procedure is described in the referenced issue, involved virio-input and input-linux. But this requires also high resolution mouse (not an usual one).

Comment 6 Peixiu Hou 2019-12-16 08:08:32 UTC
Hi Yuri,

I reproduced this issue with build virtio-win-prewhql-173, tested with a mouse support 1000/1200/1600 DPI on win2019 guest, when set mouse DPI to 1600 and change the display resolution to 2560*1600(keep the display refresh rate 64Hz, due to we cannot adjust it in guest vm), can reproduce this issue easily, the mouse move similar with the video for https://github.com/virtio-win/kvm-guest-drivers-windows/issues/385.

Steps as:
1. Boot a guest vm up with virtio-mouse-pci device, I did not use command "-object input-linux,id=mouse1,evdev=/dev/input/by-id/***":
/usr/libexec/qemu-kvm \
    -name 'avocado-vt-vm1' \
    -machine pc  \
    -nodefaults \
    -device VGA,bus=pci.0,addr=0x2 \
    -m 8192  \
    -smp 24,maxcpus=24,cores=12,threads=1,dies=1,sockets=2  \
    -cpu 'Skylake-Server',hv_stimer,hv_synic,hv_vpindex,hv_reset,hv_relaxed,hv_spinlocks=0x1fff,hv_vapic,hv_time,hv-tlbflush,+kvm_pv_unhalt  \
    -device pvpanic,ioport=0x505,id=idAHFs9n \
    -device qemu-xhci,id=usb1,bus=pci.0,addr=0x3 \
    -device virtio-scsi-pci,id=virtio_scsi_pci0,bus=pci.0,addr=0x4 \
    -drive id=drive_image1,if=none,snapshot=off,aio=threads,cache=none,format=qcow2,file=/home/kvm_autotest_root/images/win2019-64-virtio-scsi.qcow2 \
    -device scsi-hd,id=image1,drive=drive_image1 \
    -device virtio-net-pci,mac=9a:79:5b:20:70:4a,id=idP1WKM0,netdev=idfheR18,bus=pci.0,addr=0x5  \
    -netdev tap,id=idfheR18,vhost=on \
    -drive id=drive_cd1,if=none,snapshot=off,aio=threads,cache=none,media=cdrom,file=/home/kvm_autotest_root/iso/windows/winutils.iso \
    -device scsi-cd,id=cd1,drive=drive_cd1  \
    -vnc :0  \
    -rtc base=localtime,clock=host,driftfix=slew  \
    -boot order=cdn,once=c,menu=off,strict=off \
    -enable-kvm -qmp tcp:0:4448,server,nowait \
    -device virtio-mouse-pci,id=input2,bus=pci.0,addr=0xb \
    -monitor stdio

2. Change the display resolution to 2560*1600(guest supported maximum is this).

3. Change the mouse DPI to 1600. 

4. Fast move mouse to left/right. ---will saw the mouse messy drift.

Tried tested with build virtio-win-prewhql-174, cannot reproduce this issue, the mouse can move normally.

As above results, this bug seems can be verified, just I'm not sure if my steps are correct, because I didn't use "-object input-linux" command.
Could you help to confirm if correct? If yes, I'll change this issue to verified. 

BTW, we don't test with "-object input-linux" before, does it supported by downstream and what is this role? and it seems also used qemu simulation, not same with virtio input device pass-trough, if any update we need added to our test plan for this?

Thanks and Best Regards~
Peixiu

Yes, thank you, this test procedure is also correct.
In both cases (one I described and one you use) the same events come to the driver.
