[Qemu-devel] guest OS crash during shutdown/reboot

[Qemu-devel] guest OS crash during shutdown/reboot

Hi,
I have compiled qemu 0.11.0 for x86 64 bit. I run Fedora Core 10 64 bit as
my guest OS.
Sometimes, when I shutdown the guest OS gracefully (using halt command), I
see a kernel crash with a stack trace on guest OS window at *
native_machine_shutdown()*. The RIP points to *native_smp_send_stop()*. This
doesn't happen on every shutdown/reboot though.

I did see this issue in older versions of qemu too(0.10.0 and 0.10.6). This
could be a minor issue for most of you but I need to fix this because I run
some automated scripts on the guest OS which reboots it.

Does anybody has a fix or any other idea to get around this issue?

Any bit of help on this would be really helpful.

Thanks,
PurnaChandar M

The culprit seems to be a soft lockup during shutdown because of the smp
code. Adding nosmp command line option to the guest kernel does not cause
this problem.
