[PATCH v1 0/2] Disable Deprecated Features by Default on s390 CPU Models
The intention of reporting deprecated features and modifying the guest CPU model was to alleviate the user from the burden of preparing a guest with the necessary amendments to assure migration to newer hardware. While that goal was met by way of the "deprecated_features='on|off'" attribute, it still adds an extra step that the user must be aware to prepare a guest for migration and the errors that stem from an unsuccessful migration (due to feature incompatibility) is not always clear how to resolve. These patches make s390 CPU host models migration ready from the get-go by disabling deprecated features by default. They may still be disabled for other model types via the respective attribute, or reenabled if desired.

Currently, virQEMUCapsUpdateCPUDeprecatedFeatures only allows for disabling deprecated features. This locks the deprecated_features attribute to only do something if set to 'off'. Let's add a virCPUFeaturePolicy to the function's parameters which will allow the caller to decide what happens to these features. Additionally, group the relevant code in qemu_process.c.

There are no tests with deprecated_features='on'. Could you please add some before doing this change. I would also suggest to separate the code refactoring from code changes introducing an alternative behavior.

To ease the user with defining a guest with a migratable CPU model, let's disable the deprecated features from the get-go. If these features are still desired, they may be reenabled via the deprecated_features='on' attribute.

I think that Daniel's idea was when the default gets changed the user will see in the domain XML of an active domain the setting used for deprecated_features. https://lists.libvirt.org/archives/list/devel@lists.libvirt.org/message/MCDG... This does not happen. Example: I define a domain with: <cpu mode='host-model' check='partial'/> when it is started this is expanded into <cpu mode='custom' match='exact' check='partial'> ... What I expected is <cpu mode='custom' match='exact' check='partial' deprecated_features='off'> ...

The intention of reporting deprecated features and modifying the guest CPU model was to alleviate the user from the burden of preparing a guest with the necessary amendments to assure migration to newer hardware. While that goal was met by way of the "deprecated_features='on|off'" attribute, it still adds an extra step that the user must be aware to prepare a guest for migration and the errors that stem from an unsuccessful migration (due to feature incompatibility) is not always clear how to resolve.
These patches make s390 CPU host models migration ready from the get-go by disabling deprecated features by default. They may still be disabled for other model types via the respective attribute, or reenabled if desired.
