my vm is starting with libvirt xml definition file.
using sdl2|gtk ui ( not using spice client)
guest vm = windows seven
last qxl drivers
=> there is no mouse cursor visible in windows.
same with windows 8.1 guest
=> there is mouse cursor visible
there 's no problem with linux guest.
Qxl video card is necessary for dual monitor configuration under windows OS .
Any suggestion, it 's seems a bugzilla was submitted long time ago without answer.
