guest side: turn off CONFIG_KVM_CLOCK for kernels older than -rc8
host side:  either apply the kvmclock fixes or disable support by
            removing kvm clock from the capabilities bit mask.

To fix the host you need this one:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=50d0a0f987b83a8dadb1134d834e35ec410392b5

Also this as dependency to make it build:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=7af192c954017499ec163bc9dbaaee2e593d7ef2ke

Host support doesn't depend on CONFIG_KVM_CLOCK.
