Guest OS cannot detect keystrokes/mouse clicks after system_reset

Guest OS cannot detect keystrokes/mouse clicks after system_reset

[Sachin Sant]

I used system_reset command from QEMU prompt with a SLES 11
Guest. After a reset the guest came up fine with the exception
that neither key strokes nor mouse click worked.

Host OS Info :
CPU Model 	: Intel(R) Xeon(R) CPU           X7350  @ 2.93GHz

KVM Version :
kvm-84

Host Kernel :
uname -a
Linux mx3850m2 2.6.30-rc6-git4 #2 SMP Tue May 19 17:44:37 IST 2009 x86_64 x86_64 x86_64 GNU/Linux

Guest Type :
Linux SuSE Linux Enterprise 11

Qemu Command Used :
qemu-system-x86_64 -hda sles11.img -m 512

Let me know if any other information is required.

Thanks
-Sachin

The version of libSDL that you are using is probably important too.

Cheers,
Mark.

Problem is specific to SLES11 guests as it works fine on other guests like
RedHat and Fedora.  We can get around the problem by using '-no-kvm'
option.  Any clues as to how to debug such guest specific problems?

Try using -kernel and -initrd to load the kernel directly.  Maybe the 
SLES boot loader screws things up.
