No matter how old. or a Script that we Should activate?\n\nexpecting Something similar to OpenNebula:\n\n**To use PCI passthrough in OpenNebula, the devices first has to be listed. OpenNebula is using host monitor to collect the available devices. This monitor is a script that is run regularly by OpenNebula on each host. It is located at:\n\n/var/lib/one/remotes/im/kvm-probes.d/pci.rb\n\nand it is configured with a configuration file at:\n\n/var/lib/one/remotes/etc/im/kvm-probes.d/pci.conf\n\nIn this configuration, you can define which devices will be listed in OpenNebula as available for PCI passthrough. You can select devices based on PCI Id, PCI address or PCI device name. Example of configuration selecting Mellanox ConnectX-5 Virtual Functions:\n\n:filter: '15b3:1018'\n:short_address: []\n:device_name: []**\n\n![Image](https://github.com/user-attachments/assets/48df943d-8aff-4cec-beb9-340f77a53aef)\n\nThank you\n\nTata Y.","author":{"url":"https://github.com/tatay188","@type":"Person","name":"tatay188"},"datePublished":"2025-06-17T05:24:52.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/11043/cloudstack/issues/11043"}
