Hi All,
I am facing the following issue on kernel 4.14.14.
Enable SRIOV on Intel x710 card.
echo 32 > /sys/class/net/eth1/device/sriov_numvfs
start net_pool
virsh net-start intel_pool
case 1)
attach the VF while creatig VM:
virt-install --accelerate --import --disk /home/disk.img --network
network=intel_pool --boot uefi --name poza-guest --os-type linux
--os-variant rhel7 --ram 8000 --vcpus 4
case 2)
create VM:
virt-install --accelerate --import --disk /home/disk.img --boot uefi
--name poza-guest --os-type linux --os-variant rhel7 --ram 8000 --vcpus
4
attach it:
virsh attach-interface --domain oza-guest --type network --source
intel_pool --target eth1
kernel logs:
[44287.825287] i40evf 0000:01:02.0: Unable to send opcode 2 to PF, err
I40E_ERR_QUEUE_EMPTY, aq_err OK
[44287.962640] i40e 0000:01:00.0: VF 0 still in reset. Try again.
error: Failed to attach interface
error: Cannot set interface MAC/vlanid to 52:54:00:e9:f1:b5/0 for ifname
eth1 vf 0: Resource temporarily unavailable
The same use case works with following card with the same kernel version
and rootfs.
Ethernet controller: Mellanox Technologies MT27710 Family [ConnectX-4
