Does that sound about > right? 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 > I'm a bit confused about this, though.

Host support doesn't depend on CONFIG_KVM_CLOCK. HTH, Gerd -- http://kraxel.fedorapeople.org/xenner/
