[libvirt-users] ps/2 mouse cannot be removed from guest

Hi, I installed Solaris 11(x86_64) as a guest in Fedora 19 KVM host and it works well. It seems that Solaris 11 can recognize only USB mouse but cannot recognize PS/2 mouse. When a PS/2 mouse is attached to the solaris 11 guest, something conflict occured and the mouse pointer is not moving on the solaris desktop. So, I tried to remove the PS/2 mouse from the guest, but I cannot remove it using virt manager. The "remove" button is grayed out by virt manager. I have to edit the /etc/libvirt/qemu/xxx.xml file to remove it. Why is it prevented from removing the PS/2 mouse by virt manager? I hope it wil be fixed. -- hisao
