Nikolay Shirokovskiy	3bd4ed4630	xml: nodedev: add class info for pci capability ... This info can be useful to filter devices visible to mgmt clients so that they won't see devices that unsafe/not meaningful to pass thru. Provide class info the way it is provided by udev or kernel that is as single 6-digit hexadecimal. Class element is not optional. I guess this should not break users that use virNodeDeviceCreateXML because they probably specify only scsi_host capability on input and then node device driver gets other capabilities from udev after device appeared. HAL driver does not get support for the new element in this patch. Signed-off-by: Nikolay Shirokovskiy <nshirokovskiy@virtuozzo.com> Reviewed-by: Daniel P.

Michal Privoznik	1c70277886	nodedev: Export NUMA node locality for PCI devices ... A PCI device can be associated with a specific NUMA node. Later, when a guest is pinned to one NUMA node the PCI device can be assigned on different NUMA node. This makes DMA transfers travel across nodes and thus results in suboptimal performance. We should expose the NUMA node locality for PCI devices so management applications can make better decisions. Signed-off-by: Michal Privoznik <mprivozn@redhat.com>	2014-06-06 15:10:57 +02:00
Laine Stump	8807b28559	nodedev: add iommuGroup to node device object ... This includes adding it to the nodedev parser and formatter, docs, and test. An example of the new iommuGroup element that is a part of the output from "virsh nodedev-dumpxml" (virNodeDeviceGetXMLDesc()): <device> <name>pci_0000_02_00_1</name> <capability type='pci'> ... <iommuGroup number='12'> <address domain='0x0000' bus='0x02' slot='0x00' function='0x0'/> <address domain='0x0000' bus='0x02' slot='0x00' function='0x1'/> </iommuGroup> </capability> </device>	2013-06-26 14:10:56 -04:00
