Hi, as there were recently few questions about KQEMU I decided to dedicate few minutes at answering them and to post a few comments. > I'm trying to find out why qvm86 crashes the host (instant reboot when right clicking on some icons on the guest desktop). > So i thought if it is possible to use some code from kqemu-win32.c to update qvm86-win32.c No, I wrote both of the files and I can honestly tell you that copying between them will not help. There is one known case where QVM86 on WinNT platforms crashes the host machine and that's when NOEXECUTE support is enabled (see boot.ini). The method QVM86 uses for executing the code involves copying executable code into an allocated page which unfortunately has the NX bit set. I have an experimental fix for this, but I need someone with adequate environment (AMD64 and Win XP SP2+) to test it... Of course host crash can be caused by other bug. (Also note that this may apply to KQEMU too though I have no proof.) > The changelog mentions that the KQEMU accelerator is now available as > a preliminary executable for Windows.

You can compile it yourself on either Windows machine with MinGW or on linux machine with MinGW cross-compiler. I'm temporary hosting a set of QEMU / KQEMU 0.7.1 for Windows binaries here: http://www.volny.cz/xnavara/qemu-0.7.1.zip. If anyone can offer me hosting for these binaries I would be glad. As a final note (especially for Fabrice), attached are patches for KQEMU for easier driver installation (quite not there yet, but a bit closer) and implementation of kqemu_schedule (as requested). I'm planing to port this to QVM86 shortly. Best regards, Filip
