Opened: Mar 01, 2017
vCMP guests will fail to start on B2100 and B2150 when the user had enabled the input/ output memory management unit (IOMMU) before upgrading.
Cannot deploy vCMP guests.
* Run a pre-13.0.0 version of the software. * Run on a VIPRION B2100/B2150 blade. * Enable IOMMU before upgrading, using the following command: sys db kernel.iommu. * Upgrade to 13.0.0. * vCMP is provisioned.
Use the grub_open and grub_close commands to manually add "intel_iommu=on" to their kernel command line, as follows: ~$ grub_open /var/run/grub.conf.mdfy.24145 ~$ <edit the file above> ~$ grub_close
Upgrade on VIPRION B2100/B2150 blades with IOMMU enabled no longer prevents vCMP guests from starting.
