hi,

is it possible to avoid detection of clocksource=kvm_clock in a linux guest by
patching the qemu-kvm binary?
i would like to be able to avoid a guest detecting kvm-clock until bug #584516
is fixed without modifying all guest systems and reverting that later.


Newer qemu-kvm's will have this feature (using -cpu ...,-kvmclock).

with latest git, i can supply this switch, but

cat /sys/devices/system/clocksource/clocksource0/current_clocksource

still shows kvm_clock in an opensuse 11.2 64-bit or an ubuntu 10.04 64-bit guest.

Try again with tomorrow's git, I sent out a patchset earlier today that fixes this.

i don't see it in the git, do you mean:
[PATCH 0/5] Use more cpuid bits from upstream

thanks,
peter
