Some registers like the CNTVCT register should only be written to the kernel as part of machine initialization or on vmload operations, but never during runtime, as this can potentially make time go backwards or create inconsistent time observations between VCPUs. Introduce a list of registers that should not be written back at runtime and check this list on syncing the register state to the KVM state.
