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.

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.
2. Chassis switch has a trunk port that carries all VLAN traffic.
3. I have created logical networks and added VLAN tags (10, 32, 24, 40, 48 & 69).
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
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.

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.

We even attempted with replacing a trunk port with access port, but same issue continues.

What could have gone wrong? Any thing missing on oVirt configuration?

A quick help is highly appreciated.

Thanks & Regards,
