Can someone else verify that kqemu still works on FreeBSD-current? > I went back to openSUSE with the standard qemu-devel. I found that I could (usually) boot w/o problems if I put -no-acpi on the CL. Right now I have openSUSE runngin pretty well.

Now I'm thinking about giving the patched qemu-devel another try, since I've found some workarounds for booting. I'll see whether I can at least boot into the installed openSUSE using it. --- Gary Jennejohn
