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.

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

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?

Poornima.

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