to one interface in oVirt? No, not at this time. You can have one untagged network and N tagged networks on the same device, but only up to one untagged network. If you need multiple untagged networks on a single device then you're very welcome to report an RFE :) Assaf Muller, Cloud Networking Engineer Red Hat ----- Original Message ----- From: "Trey Dockendorf" <treydock(a)gmail.com&gt; To: "users" <users(a)ovirt.org&gt; Sent: Monday, February 3, 2014 10:45:44 PM Subject: [Users] Mixing tagged and untagged VLANs Using 3.3.2 I seem unable to mix tagged and untagged VLANs on a single interface. I'm trying to put the following logical networks on a host's eth0. ovirtmgmt: - Display Network - Migration Network - NOT VM Network - NO VLAN private: - VM network - NO VLAN ipmi: - VM Network - VLAN 2 In the host's network setup ovirtmgmt is already linked to eth0. If I attach 'ipmi (VLAN 2)' then try and attach 'private' the message is "Cannot have more than one non-VLAN network on one interface". Same occurs if I try and attach 'private' when only 'ovirtmgmt' is assigned to eth0. Is it not possible to have multiple untagged VLAN networks associated to one interface in oVirt?

I attempted to set ovirtmgmt to untagged and making it a VM network but that would not save. The configuration: ovirtmgmt: - Display Network - Migration Network - VM Network - NO VLAN ipmi: - VM Network - VLAN 2 When I go into a host's Network Interfaces and attempt to sync the removal of VLAN 1 from ovirtmgmt I get the following message: "Cannot setup Networks. The following Network Interfaces can have only a single VM Logical Network, or at most one non-VM Logical Network and/or several VLAN Logical Networks: eth0." So simply having one untagged and the rest tagged doesn't work. Is that expected? The use case here is simply to minimize cabling and hardware requirements as our current hypervisors have two GbE interfaces and a single IB interface. Our connectivity requirements are to 3 networks, public (direct connected to switches we have no control over for campus) and private (internal LAN) and our dedicated IPMI / Out-of-Band network (internal LAN). To interface VMs with all 3 networks and only 2 uplinks we used a tagged VLAN on our primary private network switch to link up our IPMI network as long as interface is tagged VLAN 2. The private continues to work as-is by remaining untagged. At the moment since the untagged ovirtmgmt + tagged ipmi logical network isn't allowed in oVirt we've had to explicitly set VLAN 1 (private) to tagged for specific ports on our switch. While this isn't a huge issue, to us it's an unnecessary complication of something that "should" work. I'm able to achieve the desired untagged + tagged setup using bridges in Linux when configured by hand, so I know that it technically can be done.
