The issue with SMP guests is still present. Booting with "nohz=off" resolves it. Same symptoms as before, apic_timer_fn for one of the vcpu's is ticking way slower than the remaining ones: [root@localhost ~]# cat /proc/timer_stats | grep apic 391, 4125 qemu-system-x86 apic_mmio_write (apic_timer_fn) 2103, 4126 qemu-system-x86 apic_mmio_write (apic_timer_fn) 1896, 4127 qemu-system-x86 apic_mmio_write (apic_timer_fn) 1857, 4128 qemu-system-x86 apic_mmio_write (apic_timer_fn) Let me know what else is needed, or any patches to try. ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
