VF 최대 개수 제한
| Intel | Broadcom | Mellanox |
|---|---|---|
/etc/modprobe.d/ixgbe.conf options ixgbe max_vfs=7 | /etc/modprobe.d/bnxt.conf options bnxt_en max_vfs=7 | /etc/modprobe.d/mlx5.conf options mlx5_core max_vfs=16 |
(참고) 로컬에서 작업중이라면 임시로 다음과 같이 작업할 수도 있다.
LINE 1 : NIC 드라이버 언로드 (해당 드라이버를 사용하는 NIC의 네트워크 끊어짐)
LINE 2 : 새로운 옵션을 NIC 드라이버 로드
modprobe -r ixgbe modprobe ixgbe max_vfs=7
VF 개수 선언
/etc/rc.local
echo 3 > /sys/class/net/eno1np0/device/sriov_numvfs echo 6 > /sys/class/net/enp129s0f0/device/sriov_numvfs
재시작
# reboot
VF 생성 확인
상기 rc.local 에서 sriov_numvfs 에 선언한 개수만큼 VF가 생성되었다.
