Due to a potential security issue, it's not safe to assign legacy DSA/IAA devices to virtual machines. This issue has been addressed by adding the legacy DSA/IAA device IDs to the VFIO denylist[1]. With the security issue fixed in newer DSA/IAA devices, which have new device IDs, these devices can be safely assigned to virtual machines without needing to add their IDs to the VFIOI denylist. Additionally, the new device IDs may be useful to identify any other potential issues with specific device as well in the future.
