<div>Hi,<br>
<br>
Just to add on the previous mail, the vNIC is added over a
Physical NIC that does not have any IP address, but enabled and
connected.<br>

Hi,<br>
<br>
I have a peculiar problem with oVirt 3.6. Any VM connected to
ovrtmgmt is working absolutely fine, bu the VMs (Windows Guests)
in different VLANs say 10, 32, 34, 40, 48 & 69 are not able to
even ping their respective gateways. In other words, network
packets are not coming out of the VMs at all.<br>
<br>
1. Our infrastructure consists of Lenovo Flex Chassis with 3
Lenovo x240 Compute nodes. All nodes are up and running and VMs
are also created and guest OS installed.<br>
2. Chassis switch has a trunk port that carries all VLAN traffic.<br>
3. I have created logical networks and added VLAN tags (10, 32,
24, 40, 48 & 69).<br>
4. I have attached the vNIC to each host and assigned static IP in
respective VLANs. For example in VLAN 32, the vNIC is assigned
with 172.20.101.70, subnet: 255.255.255.192, Gateway:
172.20.101.65<br>
5. VMs are mapped with respective vNIC and assigned IPs in
respective VLAN. For Example, VM in VLAN 32 has 172.20.101.79 as
IP, 255.255.255.192 as subnet and 172.20.101.65 as gateway.<br>
<br>
Now, VM is able to ping vNIC in VLAN 32, but neither VM is able to
ping the gateway nor hosts are able to ping vNIC or the VM.<br>
<br>
We even attempted with replacing a trunk port with access port,
but same issue continues.<br>
<br>
What could have gone wrong? Any thing missing on oVirt
configuration?<br>
<br>
A quick help is highly appreciated.<br>

<br></blockquote></div><br></div><div class="gmail_extra">Only a guess: On the VM OS, do not define any VLAN on its vnics. Each VM that is assigned to a vlan network on the host will have its traffic tagged only when traffic will go out of the network to the 'world'. So the VM is not aware that the traffic will be tagged when passing through the host.<br><br></div><div class="gmail_extra">If this is not the case, please share the screenshots of what you configured for one of the networks (including the vnic) and on the VM.<br><br></div><div class="gmail_extra">Thanks,<br></div><div class="gmail_extra">Edy.<br></div></div>
