I tested libvirt 6.0.0-0ubuntu8.7~ppa1 on a z15 SE enabled LPAR in Ubuntu 20.04.
I can now add "<driver iommu='on'/>" to the vsock section in the Libvirt XML file.
Qemu then runs with the 'iommu_platform=on' argument of the vsock device driver.
Communication between the hypervisor and a SE enabled KVM guest via Vsock now works as expected.
Thanks for the quick fix!
