Well, that's certainly the wrmsr instruction. But I don't see how this can happen.

Can you patch set_efer() in x86.c to print the value of the efer argument and of efer_reserved_bits?

Yes, but apparently set_efer() is never called. To verify, I patched kvm_set_msr_common() to print the msr parameter:


On 32-bit, we might actually reach the default: label of the switch in vmx_set_msr(). Can you add a printk() there? print both msr_index, and, if msr is not NULL, msr->index and msr->data.
