When I run Tiny Core Linux in a Qemu virtual machine, the guest mouse pointer is severely misaligned with the host mouse pointer. In the screenshot below, the guest mouse pointer is the one in the image. The red dot marks the location of the host mouse pointer.
I create the Qemu disk image with this command:
qemu-img create disk.img 500M -f qcow2
and launch the virtual machine with this command:
qemu-system-x86_64 -m 1024 -boot d -enable-kvm -smp 3 -net nic -net user -hda disk.img -cdrom TinyCore-current.iso
That starts a VNC session running on
::1:5900, which I access with Remmina by specifying
localhost:5900 as the server.
I'm using Remmina 1.3.3, Qemu 1.3.1, and Debian 10 ("Buster"). How do I correctly align these mouse pointers? The guest machine is difficult to use when they're misaligned.
EDIT: This issue also shows up in TigerVNC Viewer 64-bit v1.9.0, so it seems like it isn't a Remmina problem, but rather a Qemu problem.
EDIT: To clarify, in my version of qemu , I get the error
qemu-system-x86_64: -usbdevice tablet: '-usbdevice' is deprecated, please use '-device usb-...' instead, but when I use the
-device usb-tablet option I get the error
qemu-system-x86_64: -device usb-tablet: No 'usb-bus' bus found for device 'usb-tablet'. I've seen this suggestion on this site and elsewhere, but it doesn't seem like it's a proper, compatible solution to my problem.
