This RFC patch series introduces initial libvirt support for guest
dedicated crypto adapters on S390.
It essentially allows to specify a vfio-ap mediated device in a domain.
Extensive documentation about AP is available in patch 6 of
the QEMU patch series.

Maybe it is time to explain what the models actually are? Or is this not
in the scope of libvirt's documentation?
I am not sure what the libvirt policy
regarding the documentation is.
Therefore it would be good if some familiar with it could answer this
question.
I just stuck to the style of the already supported vfio models.

This RFC patch series introduces initial libvirt support for guest
dedicated crypto adapters on S390.
It essentially allows to specify a vfio-ap mediated device in a domain.
Extensive documentation about AP is available in patch 6 of
the QEMU patch series.
