A question about pci nic passthrough.
Apologies if an answer exists for this.
I searched the forum but couldn’t find it.
If you can passthrough the pci nic to the vm, please tell me how.
Thank you very much.

Yep, you’d want something like:
This will track down the PCI device for the interface eth1
on the host, detach it from the driver and pass the device to the VM.
An alternative would be:
Which is a generic PCI passthrough device. The former is preferred as having it as a nic device means that LXD will place the device in a virtual PCI slot in the range we use for NIC devices. This should reduce the likelihood of the address on the guest’s PCI bus changing and so keep a stable interface name in the VM.
Thank you very much @stgraber.
01, My environment is nested vm
Levono p15s - windows 10 - vmware worstation 16 - ubuntu 21.04 - c01(vm, centos 8.4)
enx nic is a usb nic card that is passthrough from host (window10) to ubuntu. And passthrough this enx back to the vm. (nested passthrough)
Thank you very much.
I don’t think we support non-PCI network cards at this time. As you say, this is a USB NIC.
One option you could do however is to use a NIC type of macvlan
to use that parent NIC in your VM.
E.g.
lxc config device add VM1 eth1 nic nictype=macvlan parent=eth1
It’s working very well.
The purpose of testing this is to test LACP on the vm.
Have a nice weekend.
Thank you very much. ^^
Great! The only limitations are that the VM won’t be able to communicate with the host (this is a limitation/feature of macvlan) and that it can only have 1 MAC address.
