Otherwise Linux boot stops with this error: MP-BIOS bug: 8254 timer not connected to IO-APIC So the multimedia timer is added again here.Which distribution and Windows version is that? Also, have they tried the non-dynticks timer (win32)?Paolo
The bug was reported for a tinycore 3.5.1 guest (linux kernel 3.6.33-3).The iso image is available from http://distro.ibiblio.org/tinycorelinux/3.x/release/.
QEMU was running on XP SP3. Other Linux live CD-ROMs (e.g. FC14) were reported to show the same bug when run as guest. APIC can be disabled (kernel parameter), without APIC there is no problem. I see the same bug here with two XP hosts and also tried both timer variants of current QEMU (without a difference). I don't get the bug when running on a Linux host using wine. Regards, Stefan
