The mouse pointer will be drawn by the Android system being run by the 'Fast Model'. Despite having the name 'fast', the emulation of the ARM system is a lot slower than real hardware, and for the first few minutes after boot the Android system tends to be very busy doing various background task and doesn't have much emulated cycles for updating the display. However, I see from you screen shots that the emulator has been running for 20 minutes, which should be enough time.
I also see from the screenshots that you are running a model with one emulated CPU. Can you say which fast model you are running? Is it one of the pre-built ones that ARM supplies? And which Linaro Android build/release are you working with? I want to see if I can reproduce the problem.

I download fastmodel from https://silver.arm.com/browse/FM000. Branch is:Fast Models 8.3 for Linux The loaded project is: RTSM_VE_Cortex-A15x1.sgproj Linaro-android : vexpress-linaro-13.09-release, download from http://snapshots.linaro.org/android/~linaro-android/vexpress-linaro-13.09-re...

I know this bug --> https://bugs.launchpad.net/linaro-android/+bug/1227665 doesn't have exactly the same symptoms as you describe, but it was my experience that on a fast model emulating a single CPU it was very difficult to get Android to be usable, could you try with an A15x2 model?
Linaro-android : vexpress-linaro-13.09-release, download from http://snapshots.linaro.org/android/~linaro-android/vexpress-linaro-13.09-re...
Any reason not to use a newer release? If for no other reason than the later releases have the boot animation disabled which makes boot times go a lot faster. (You may have disabled boot animation yourself?)
I also know for all vexpress-linaro-14.??-release's this year I have personally booted them OK on a A15x2 model. Though because they are rather slow and difficult to use I usually unlock the display by running the 'disablesuspend.sh' command from the Android console, as using the mouse to unlock the screen is extremely difficult.
Dear Tixy, I am glad to get your help.I have tried that a fast model is with an A15X4,but the trouble is working.And do you give me help again?
