[SOLVED] noVNC & Windows XP KVM mouse pointer alignment

Hi all,

When I use the noVNC option to view an XP KVM, the host system mouse pointer never aligns with the VM mouse pointer. Attempting to use the VM in this manner is similar to pushing strings. :)

I found an old thread about the issue but nothing was fully resolved.

The mouse pointer aligns fine with a Win 7 KVM albeit with a little lag.

When I use a VNC client to view the XP VM, such as Remmina, the mouse pointer aligns nicely with no lag.

I am using Firefox 52.8 ESR. I tried chromium and google-chrome and saw the same alignment issues.

The qemu guest agent and virtio drivers are installed with no related event viewer issues. The Proxmox host is configured with the qemu agent enabled.

Any ideas how to fix?

why do you specify 'qxl' as display (spice) and use novnc? use spice instead

also maybe setting tablet to 1 helps (with 'qm set <VMID> -tablet 1')
