Severity: 3-Major


With vCMP provisioned, upgrading to 13.1.x or later release will not enable IOMMU support after the upgrade.


Guests configured with FIPS functionality will fail to start until IOMMU is enabled.


-- Upgrading to 13.1.x or later. -- vCMP already provisioned. -- Running on the BIG-IP 10350F platform.


You can use either of the following workarounds: -- Re-provision vCMP after the upgrade to enable IOMMU support. 1. Modify the value of the DB variable kernel.iommu to 'enable'. 2. Restart the BIG-IP system.
