Hi all,

We are running an oVirt 4.4 Hosted Engine as a VM, and after changing the Cluster's BIOS type from Q35 with Legacy BIOS (the default one after installation) to Preexistent, the VM fails with the following error:

XML error: The device at PCI address 0000:00:02.0 cannot be plugged into the PCI controller with index='0'. It requires a controller that accepts a pcie-root-port.


We need it so that we can run imported VMs from a previous version of oVirt, namely 4.0.
Applying the BIOS settings individually works but as an attempt to generalize the settings we decided to apply it to the full cluster.

Tell me if you need more data.



Cheers,
