Hello,
testing what in subject, without the tablet definition in guest I'm unable to use my mouse:
the pointer moves, but the click doesn't produce any effect...

Instead the graphical install phae of F18 tc7 from netinst.iso in the same vm was without problems regarding mouse, only after reboot

I supposed that nowadays tablet was not necessary any more....
(I was told it consumed cycles of cpu to have it inside guest)
Any hints?

The link in xml file I had to add for the mouse to be able to work was:

<input type='tablet' bus='usb'/>

Thanks,
Gianluca
