Re: [ovirt-users] ?==?utf-8?q? 2 Vlans on one VM nic
That's what I understood
I don't have problem configuring VLANs on nics and switches, I've already done
many times
What I said is
If I have 3 VMs
VM1 needs vlan1 and 2
VM2 needs vlan3 and 4
VM3 needs vlan5 and vlan6
for security reason I don't want any of these VM to be able to "see" traffic
of other VLAN
I will need 3 interfaces, one per trunk
Could Vswitch be the solution ? It seems to be implemented in ovirt, but documentation
looks very poor ( or I didn't find the documentation ;) )

No, on the hypervisor side you will have a physical nic that you configure
as non tagged network in ovirt.
The port on the physical network switch where the physical nic connects
should be configured as a trunk and allow all the vlan ids you want it to
transport.
Then on the vm you configure one single vnic on this oVirt network and
configure at os level all the vlan ids you want into the vm itself. See
here for the methods landing page:
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/...
And this for the manual one and ifcfg files syntax:
