Did you test non-BSD guests, too? > Oh yes I tested Linux too (and FreeBSD), and I tested a Windows 7 beta guest that I had installed a while ago more out of curiosity than anything else, and that one seemed to bluescreen a little less than it used to also... (it usually only bluescreen at boot and sometimes at shutdown, once it gets past the boot stage it keeps running, altho slowly. Oh and -kernel-kqemu seems to always make it bluescreen so only `regular' kqemu is useful for that guest.) Everything else I tested seemed to still run like it used to, the Linux guests even _appeared_ to run a little faster than they used to, possibly because of the added verr/verw and lar/lsl handling in Jan's patches... > I noticed that Adrian has patches for OpenBSD host support in their > ports CVS repository, as pointed out by Mikolaj. > There appears to be some FreeBSD code in-tree though - so, is the > above patch the only one you've queued, or do you have host patches as > well that we could push "upstream"? I have a few more, as you can see on cvsweb: http://www.freebsd.org/cgi/cvsweb.cgi/ports/emulators/kqemu-kmod-devel/files/ (patch-tssworkaround is only applied for FreeBSD < 7.1 since later versions no longer have the issue it works around; look in that patch's commitlogs if you want links to the gory details...)
