Introduce a new method to get an immutable reference to the kvm_run struct. Replace uses of `as_mut_ref()` with `as_ref()` where possible. Signed-off-by: Carlos López <[email protected]>
Add support for bus lock detection. The feature can be enabled via KVM_CAP_X86_BUS_LOCK_EXIT, which enables a new exit (KVM_EXIT_X86_BUS_LOCK) and a new flag (KVM_RUN_X86_BUS_LOCK) in the kvm_run->flags field. Add two tests as well to verify that enabling the feature works. Signed-off-by: Carlos López <[email protected]>

Can we also check the inner error? Maybe using .errno() like in other tests.

nit: I would prefix the name with is_ (is_bus_...) to match the naming conventions used for such functions.
Also, can we add a test for it?
