Hi Eric, Thanks for pointing this out. This BP (https://blueprints.launchpad.net/zun/+spec/use-privsep) was created to track the introduction of privsep.

Re: [openstack-dev] [zun][unit test] Any python utils can collect pci info?
You may get a little help from the methods in nova.pci.utils. If you're calling out to lspci or accessing sysfs, be aware of this series [1] and do it via the new privsep mechanisms.

Re: [openstack-dev] [zun][unit test] Any python utils can collect pci info?
Hi Shunli, I am not aware of any prevailing python utils for this. An alternative is to shell out Linux commands to collect the information. After a quick search, it looks xenapi [1] uses “lspci -vmmnk” to collect PCI device detail info and “ls /sys/bus/pci/devices//” to detect the PCI device type (PF or VF). FWIW, you might find it helpful to refer the implementation of Nova’s xenapi driver for gettiing PCI resources [2]. Hope it helps.

Hi all, For https://blueprints.launchpad.net/zun/+spec/support-pcipassthroughfilter this BP, Nova use the libvirt to collect the PCI device info. But for zun, libvirt seems is a heavy dependecies. Is there a python utils that can be used to collect the PCI device detail info?
