[et-mgmt-tools] Adding -usbdevice=tablet for qemu domains

[Jonathan Underwood]

Hi,

I am using virt-manager to create a guest Windows XP installation
using qemu-kvm. I am finding that the mouse doesn't work well in
virt-manager sessions, but it works fine when starting a qemu SDL
window from the command line. My reading leads me to understand this
is because virt-manager sessions use VNC to communicate with the guest
domain.

Further reading about qemu-dm and VNC and mice suggests that the way
around this ubiquitous problem is  gotten around by passing
usbdevice=tablet to qemu. So my question is, how to do this within
virt-manager/virsh?

Also, given that this problem won't go away until the VNC client is
fixed, and that this same issue affects Xen domains, wouldn't this be
a useful defaul anyway?

Thanks,
Jonathan
