ubuntu 里的virtualbox热键修改，急啊，跪求

用KVM装了个XP，现用vnc applet的方式远程访问，能打开虚拟机桌面，但是出现两个鼠标，也就是原系统的那个并没有隐藏起来。如果用VNCVIEWER客户端，打开该实例是正常的。
启动参数大致如下：
/usr/bin/kvm -S -M rhel6.1.0 -enable-kvm -m 1024 -smp 1,sockets=1,cores=1,threads=1 -name i-3FF40709 -uuid 9a796b1c-f573-ec9e-a5e1-c30616621a0a -nodefconfig -nodefaults
-chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/i-3FF40709.monitor,server,nowait
-mon chardev=charmonitor,id=monitor,mode=readline -rtc base=utc -boot c
-drive file=/opt/kProject/instance/admin/i-3FF40709/disk
-device virtio-blk-pci,bus=pci.0,addr=0x4,drive=drive-virtio-disk0,id=virtio-disk0
-drive file=/opt/kProject/instance/admin/i-3FF40709/disk2
-device virtio-blk-pci,bus=pci.0,addr=0x5,drive=drive-virtio-disk1,id=virtio-disk1
-device virtio-net-pci,vlan=0,id=net0,mac=d0:0d:3f:f4:07:09,bus=pci.0,addr=0x3
-net tap,fd=28,vlan=0,name=hostnet0
-chardev file,id=charserial0,path=/opt/kProject/instance/admin/i-3FF40709/console.log
-device isa-serial,chardev=charserial0,id=serial0
-usb -vnc :14135,password -vga cirrus
-device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x6

请大家多多指教，谢谢啦~
