Can you try moving the kvm_make_request() inside the if conditional and
see if it that also fixes it?
yes, changing to:
if (unlikely(vcpu->cpu != cpu) || check_tsc_unstable()) {
kvm_make_request(KVM_REQ_CLOCK_UPDATE, vcpu);
/* Make sure TSC doesn't go backwards */
s64 tsc_delta = !vcpu->arch.last_host_tsc ? 0 :

is also OK.

what about changing:
if (check_tsc_unstable()) {
kvm_x86_ops->adjust_tsc_offset(vcpu, -tsc_delta);
vcpu->arch.tsc_catchup = 1;
kvm_make_request(KVM_REQ_CLOCK_UPDATE, vcpu);
}

to:

if (check_tsc_unstable()) {
kvm_x86_ops->adjust_tsc_offset(vcpu, -tsc_delta);
vcpu->arch.tsc_catchup = 1;
}
kvm_make_request(KVM_REQ_CLOCK_UPDATE, vcpu);

this fixes thinks for me as well..
n.
?

Can you send a patch which does that? I think this is the correct fix.

Thanks,

Zach
