If q35 machine type is detected the slot of the pci device is set to 0
and the bus to pci_id + 1.
Q35 models uses pcie-root-ports to attach PCI devices. Each PCI port is
selected by the bus parameter of the PCI address and it that does not accept a
slot number greater than 0.
Example:
A VM with 2 X710 VFs is defined OpenNebula as:
PCI=[
ADDRESS="0000:44:0a:0",
BUS="44",
CLASS="0200",
DEVICE="154c",
DOMAIN="0000",
FUNCTION="0",
NUMA_NODE="0",
PCI_ID="0",
SHORT_ADDRESS="44:0a.0",
SLOT="0a",
VENDOR="8086",
VM_ADDRESS="01:00.0",
VM_BUS="0x01",
VM_DOMAIN="0x0000",
VM_FUNCTION="0",
VM_SLOT="0000" ]
PCI=[
ADDRESS="0000:44:0a:1",
BUS="44",
CLASS="0200",
DEVICE="154c",
DOMAIN="0000",
FUNCTION="1",
NUMA_NODE="0",
PCI_ID="1",
SHORT_ADDRESS="44:0a.1",
SLOT="0a",
VENDOR="8086",
VM_ADDRESS="02:00.0",
VM_BUS="0x02",
VM_DOMAIN="0x0000",
VM_FUNCTION="0",
VM_SLOT="0000" ]
Each PCI VFs is attached to different pcie-root-port, selected with the
VM_BUS parameter:
00:02.0 PCI bridge: Red Hat, Inc. QEMU PCIe Root port
00:02.1 PCI bridge: Red Hat, Inc. QEMU PCIe Root port

Taking OpenNebula for a Test Drive
There are a couple of very easy ways to try out the OpenNebula functionality
- miniONE for infrastructures based on open source hypervisors.
- vOneCloud for VMware based infrastructures.
Installation
You can find more information about OpenNebula’s architecture, installation, configuration and references to configuration files in this documentation section.
It is very useful to learn where log files of the main OpenNebula components are placed. Also check the reference about the main OpenNebula daemon configuration file.
Front-end Installation
The Front-end is the central part of an OpenNebula installation. This is the machine where the server software is installed and where you connect to manage your cloud. It can be a physical node or a virtual instance.
Please, visit the official documentation for more details and a step-by-step guide. Using the packages provided on our site is the recommended method, to ensure the installation of the latest version, and to avoid possible package divergences with different distributions. There are two alternatives here: you can add our package repositories to your system, or visit the software menu to download the latest package for your Linux distribution.
If there are no packages for your distribution, please check the build dependencies for OpenNebula and head to the Building from Source Code guide.
Node Installation
After the OpenNebula Front-end is correctly set up, the next step is preparing the hosts where the VMs are going to run. Please, refer to the documentation site for more details.
