Public bug reported: Problem: vsock can't be used with Secure Execution ---uname output--- Linux se1 5.4.0-62-generic #70-Ubuntu SMP Tue Jan 12 16:27:38 UTC 2021 s390x s390x s390x GNU/Linux Machine Type = z15 8562 ---Debugger--- A debugger is not configured ---Steps to Reproduce--- In a Secure Execution environment the Qemu driver vhost-vsock-ccw driver requires the argument "iommu_platform=on".
E.g. "qemu-system-s390x -device vhost-vsock-ccw,guest- cid=42,iommu_platform=on ..." Currently Libvirt does not support this argument. Therfore Vsock can't be defined in XML correctly.
