[libvirt] PCI devices passthough to LXC containers using libvirt
Hi All
Please let me know if anyone have given access to
PCI devices for a LXC container.
I have tried getting the xml from
"virsh nodedev-dumpxml pci_device" and
added to the libvirt xml file as shown below
<device>
<name>pci_0000_03_00_0</name>
<parent>pci_0000_00_03_0</parent>
<driver>
<name>nvidia</name>
</driver>
<capability type='pci'>
<domain>0</domain>
<bus>3</bus>
<slot>0</slot>
<function>0</function>
<product id='0x06fd' />
<vendor id='0x10de'>nVidia Corporation</vendor>
</capability>
</device>
But it didn't work. I see the logs and it says
couldn't get physical and virtual functions of these devices with error
get_physical_function_linux:323 : Attempting to get SR IOV physical function for device
with sysfs path '/sys/devices/pci0000:00/0000:00:00.0'

virtual functions for devicewith sysfs path

If anyone got some guidelines how to debug, please let me know.
Thanks in advance
