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. Libvirt Version is 6.0.0-0ubuntu8.5.
