how can fstack uses sr-iov(vf) #734

Hello, I want to modify config.ini so that f-stack can use vf. Is there any case?

uvletter commented 1 year ago

just set pci_whitelist to the pci address of VF

CHRIS123540 commented 1 year ago

Thank you for your answer, I did not use pci_whitelist, I directly set the port_list parameters and correctly obtained the MAC address of VFs, but I can only ping the address of the PF that created VFs. 20230213203646 20230213204554 ZOLY098}V235AQNE4I}78V8 20230213205511 I would appreciate it if you could give me some advice

Use the command lspci to find out the pci address of the VF, and then replace pci_whitelist with it, if not I guess fstack would bind to the first available pci device, i.e. the PF.

If you use multi port in one subnet, maybe you should use ff_ipfw to set some policy routing.

Or you can try set every port to different subnet and retry it.

May be you can get some info with google search rp_filter.

Setting different subnets works, could you tell me why?
