Description Qunfang Zhang 2009-09-22 05:27:22 UTC
Description of problem:
After migrated the rhel3.9-32 guest with smp kernel, the mouse and keyboard are abnormal. For example, I input the command "ls" in the terminal, but it will display "llllllssssss". And also when I right-click mouse on the desktop of guest to create a "New Window" or "New Folder", two or more windows or folders will be created rapidly.

And the issue does not occurs every time, when implement ping-pong migration it will be more easy to reproduce.

Version-Release number of selected component (if applicable):

How reproducible:
Not everytime but always

Steps to Reproduce:
1.Install a rhel3.9-32 guest and install smp kernel.
2.Boot rhel3.9-32 guest with smp kernel on source host and also on destination host with listening mode.
/usr/libexec/qemu-kvm -no-hpet -usbdevice tablet -rtc-td-hack -smp 4 -m 4G -net nic,vlan=0,macaddr=00:1a:4a:01:22:39,model=rtl8139 -net tap,vlan=0,script=/etc/qemu-ifup -drive file=/mnt/rhel3.9-32-smp.raw,media=disk,if=ide,index=0 -cpu qemu64,+sse2 -uuid c8647283-4f32-4d9c-a8be-a37d6edd2cd2 -monitor stdio -vnc :10 -boot c(-incoming tcp:0:5800)
3.Implement ping-pong migration for about 3 times.
4.Open a terminal in the guest and input "ls".
5.Implement migration again if this issue cannot reproduce. 
Actual results:
In the terminal of guest, "lllllssssss" will display

Expected results:
In the terminal of guest "ls" command display.
