Dec 23, 2010I just noticed this in /config/tmm_base.tcl:
----------------------------------------------------------------------------------------------
if { [string compare $platform "C36"] == 0 } {
scheduler::rtc_frequency 2048
scheduler::sleep_range 122070 1000000
} elseif { [string compare $platform "Z99"] == 0 } {
scheduler::sleep_range 1000000 1000000
VirtualBox has a disagreeable LAPIC. Workaround by using the RTC
if { [ file exists "/var/run/VirtualBox" ] } {
scheduler::rtc_frequency 256
scheduler::use_rtc true
} else {
scheduler::rtc_frequency 1024
scheduler::use_rtc false
}
}
----------------------------------------------------------------------------------------------
and this in dmesg:
----------------------------------------------------------------------------------------------
ENABLING IO-APIC IRQs
..TIMER: vector=0x31 apic1=0 pin1=2 apic2=0 pin2=0
Using local APIC timer interrupts.
WARNING calibrate_APIC_clock: the APIC timer calibration may be wrong.
ACPI: Using IOAPIC for interrupt routing

* Found PM-Timer Bug on the chipset. Due to workarounds for a bug,
* this clock source is slow. Consider trying other clock sources

So on Xen you might want to touch /var/run/VirtualBox
