[Qemu-devel] KQEMU API change

[Fabrice Bellard]

Hi,

I just committed a few changes in the KQEMU API. People wishing to use
kqemu with the current QEMU version from the repository should download
the new KQEMU release (version 1.4.0pre1).

Fabrice.

Thanks for the great tools.

I've encountered a compile failure with KQEMU 1.4.0pre1.
I did not see anything in the kqemu-doc.html file which spoke to 
requirements ... nor on the website.  forgive me if I've overlooked 
something.

The addition of the following include in kqemu-linux.c allows for successful 
compilation:

#include <linux/sched.h>

Thanks again!
