Hi!
Is there any way to have high resolution clock sources?
Currently the native kvm tool seems to support only jiffies:
$ cat
/sys/devices/system/clocksource/clocksource0/available_clocksource
jiffies
Using qemu-kvm with the same kernel/host I can use tsc, hpet, acpi_pm.
Thanks,

We'll do kvm_clock as well if you compile it in the kernel.
CONFIG_HIGH_RES_TIMERS is on both host and guest kernels enabled.
BTW: Why adds the kvm tool notsc to the guest's kernel command line?
I don't think that

You'll need CONFIG_KVM_CLOCK.
I'm not actually sure how close our implementation is to having tsc
working so far, Cyrill knows more about that than me.
We dropped tsc while were debuggin timer interrupts and

Yup, notsc was used in the early days to avoid APIC emulation.
Anyone care to send a patch to drop it from master?
