I can reproduce with the following cmd: (without sse4.1, sse4.2)

/usr/libexec/qemu-kvm -drive file=/root/win2008r2-64-virtio.bak,index=0,if=virtio,media=disk,cache=none,format=qcow2,boot=on -net nic,vlan=0,model=virtio,macaddr=9a:2d:20:42:2a:60 -net tap,vlan=0,ifname=t0-140400-SfXj,script=/usr/Auto/autotest/client/tests/kvm/scripts/qemu-ifup-switch,downscript=no -m 2048 -smp 2,cores=1,threads=1,sockets=2 -cpu qemu64,+sse2 -vnc :0  -rtc-td-hack -M rhel5.6.0 -usbdevice tablet -boot c -monitor stdio -drive file=/root/storage.qcow2,index=1,media=disk

Which vnc client you are using?

Comment 4 Gerd Hoffmann 2010-11-30 09:25:43 UTC

How do you send Ctrl-Alt-Del?  Using the F8 menu?

In case windows doesn't accept the password:
Does it help to press the left Ctrl key once?
Does it help to press the left Alt key once?

Comment 5 Gerd Hoffmann 2010-11-30 09:26:39 UTC

Is possibly a duplicate of bug #643317

Comment 6 Gerd Hoffmann 2010-12-01 08:11:32 UTC

Can you test whenever kvm-83-218.el5 fixes the bug please?

Comment 7 Suqin Huang 2010-12-02 06:28:42 UTC

1. reproduce in kvm-83-213.el5
keyboard work after pressing the left Ctrl key once.
keyboard doesn't work after pressing the left Alt key once.

Ctrl+Alt+Delete is sent by F8 menu in bug #643317, Ctrl+Alt+Delete is sent by kerboard in this bug. they are not duplicate.

2. Can not reproduce in kvm-83-218.el5
