Hi,
I have a VM using SRIOV interfaces based on X710 interfaces. This VM is connected to a physical router through the VF.
I would like to enable vlan tagging on the VM.
I can ping the physical router from the VM if I'm not using VLAN tagging on the interface.
When I add VLAN tagging on the interface (on the VM and on the physical router), the network connectivity is broken.
The physical router correctly receives the packets/frames from the VM.
The VM receives the packets/frames but without a VLAN tag, it seems that the VLAN tag has been stripped.
Here are some informations on my setup:
[root@SLI-SRV3 sysadmin]# ethtool -i eth1

[root@SLI-SRV3 sysadmin]# ip link show eth1

VIRSH network config:
<interface type='hostdev' managed='yes'>

<driver name='vfio'/>
<source>
<address type='pci' domain='0x0000' bus='0x19' slot='0x02' function='0x0'/>
</source>
<alias name='hostdev0'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/>
</interface>
Any idea about what could be the issue ?
Thanks,
Stephane
