It is possible that you got hit by the kqemu tsc vs smp problem, i.e. passing `notsc' to the guest kernel or forcing qemu onto one cpu (cpuset -l 0 qemu ...) may have helped there, sorry I should have thought of that earlier... Also, did I get that right that this opensuse 10.3 install worked with the original qemu-devel port (without kqemu)? So we do seem to have a regression here... (thats a 20080620 qemu svn snapshot, for the folks on the qemu list.) Thanx, Juergen
