[Xen-changelog] [qemu-xen-unstable] xen: don't initialize the RTC timers if xen is available

    xen: don't initialize the RTC timers if xen is available
    
    Xen doesn't need full RTC emulation in Qemu because the RTC is already
    emulated by the hypervisor. Hence don't initialize the RTC timers when Xen 
is
    available so that Qemu doesn't need to wake up needlessly.
