Hi,
> Result:mouse can not be used in guest
Which means what? Not working at all? No mouse pointer visible?
Is the spice guest agent installed?

Hi Gerd, Actually, there are two mouse in the guest, one mouse could be seen but another one which has actual control can't be seen, this bug will be happened when guest is using vnc+qxl mode and has feature <vmport state='off'/> but has not tablet in xml, so there is no service spice-vdagentd running in guest,thanks. Hmm, yes, qxl wants move the mouse pointer (on guest request). vnc doesn't support that (no rfb protocol message). No easy way out. No new issue, no regression, certainly not 7.3 material.

I think we can close this as wontfix (unsupported corner case). areis? spice is recommended for qxl anyway, and in absolute mode (i.e. with tablet, which is usually the case) qxl+vnc works fine too.

If the guest is rhel5.11, the mouse can't be used normally no matter graphic mode is spice+qxl or vnc+qxl even if guest doesn't have feature <vmport state='off'/> but have tablet <input type='tablet' bus='usb'> in xml
