Now testing with core-advanced zone. I have configured several traffic types and have defined the labels for them. For example the public network is defined at the physical network 1 and has label cloudbr0 as below: [image: image.png] But I am not able to add a vNIC at the guest VM which will be connected at the cloudbr0 interface. Whatever I try all the VM NICs will be connected at the guest network which is cloudbr2. > Try network with vlan = "vlan://untagged" > For some reason all guest networks get a VLAN from the guest VLAN range defined at the initial zone creation.

What type of zone and network do you use ? Try network with vlan = "vlan://untagged" On Friday, May 17, 2024, Alex K wrote: > Hi All, > > Is it possible to create untagged guest networks in cloudstack and have > them assigned to different OVS bridges? > > I have created several OVS bridges at the KVM host and then tried to attach > the different VM NICs to the different OVS bridges without any VLAN > tagging, but it seems that whatever I try there is always VLAN tagging at > the guest VM interfaces at the VLAN ID range given at the initial zone > creation. > > Also any NIC I add at the VM seems to be mapped only at the single guest > network.

I understand this is not possible in cloudstack?

Create untagged guest VMs
Hi All, Is it possible to create untagged guest networks in cloudstack and have them assigned to different OVS bridges? I have created several OVS bridges at the KVM host and then tried to attach the different VM NICs to the different OVS bridges without any VLAN tagging, but it seems that whatever I try there is always VLAN tagging at the guest VM interfaces at the VLAN ID range given at the initial zone creation. Also any NIC I add at the VM seems to be mapped only at the single guest network. Although I have defined different types of networks (guest, management, public) during zone creation, defining also the traffic labels according to the OVS bridge names, there does not seems to be a way to attach these different networks to the different OVS bridges through the cloudstack UI. My intention is to have the VM connected to different networks, with or without VLAN tag. I am testing now with an edge zone with a KVM server. Thanks for any input. Alex
