This change addresses a long-standing issue in rST documentation imported from XML. That import process added backslash escapes in front of various characters. The three most common being '(', ')', and '_'. These instances are removed. Signed-off-by: Ron Stone <ronald.stone@windriver.com> Change-Id: Id43a9337ffcd505ccbdf072d7b29afdb5d2c997e

PCI Device Access for VMs
You can provide with passthrough or access to network interface cards and other devices.
Note
To use passthrough or devices, you must have Intel-VTx and Intel VT-d features enabled in the BIOS.
Note
When starting a where interfaces have binding_vif_type, the following parameter is required for the flavor, hw:mem_page_size=large enabled
where, page size is one of the following:
- small: Requests the smallest available size on the compute node, which is always 4KiB of regular memory.
- large: Requests the largest available huge page size, 1GiB or 2MiB.
- any: Requests any available size, including small pages. uses the largest available size, 1GiB, then 2MiB, and then 4KiB.
For a network interface card, you can provide access by configuring
the network interface. For more information, see Configuring PCI Passthrough
Ethernet Interfaces <configure-pci-passthrough-ethernet-interfaces>
.
For other types of device, you can provide access by assigning a
alias to the device, and then referencing the alias in a flavor extra
specification. For more information, see Expose a Generic PCI Device for
Use by VMs <expose-a-generic-pci-device-for-use-by-vms>
