Hi,
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.

Hi,
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.

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.
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.
Thanks,
Edy.
