Hi Kai, DNS configuration should be supported in the next oVirt version (4.2). In the meantime, editing the config manually as you did is the way to go. Thanks, Edy. On Tue, Apr 18, 2017 at 5:29 PM, Kai Wagner wrote: > Ok I found /var/lib/vdsm/persistence/netconf/ and fixed

Re: [ovirt-users] Passing VLAN trunk to VM

Passing a trunk to the vnic is supported long ago. Just create a network over a nic/bond that is connected to a trunk port and do not define any VLAN (we call it non vlan network). In oVirt, a non-vlan network will ignore the VLAN tag and will forward the packets as is onward. It is up to the VM

Re: [ovirt-users] Virtual Machines on same host / traffic stays local?

If the VM/s vnic/s are connected to the same network, then traffic will be forwarded by the bridge defined for that network, therefore for local VM/s the traffic will not exit the host. I'm not exactly clear what do you mean by "configured for bridging". Thanks, Edy. On Wed, Apr 26, 2017 at 2:30

Re: [ovirt-users] Recognizing Subinterfaces on oVirt Host

Hello, The sub-interface you are referring to is just an alias for adding a secondary IP to the same interface. In networking terms, it is the same network with multiple subnets (some can even overlap) and there is no separation between them. oVirt networks are considered layer 2, as such, only

Hi Alan, The oVirt host agent (VDSM) has a multi-gateway/sourceroute feature which allows gateways to be specified per network, in addition to the host level routes. By default and depending on which version you use, only the ovirtmgmt (management) network defines the host default route but all

Hi, Just adding to what Charles mentioned the patch that allowed this on the host side: https://gerrit.ovirt.org/#/c/66127/ Note that for a tipical VM network, one would not usually define an IP address, as it exposes the host to the VM/s. When a vnic is connected to the network, it will have L2

Hello Gianluca, Not sure if I can help with this one, but could you just clarify from where these DHCPv6 packets arrive? You mentioned IPv6 is disabled on the VM, therefore I assume these are ingress packets, right? If this is the case, then perhaps the stack just drops the ingress packets (as it

Not sure if I understand what you are asking here, but the need for a gateway per network has emerged from the need to support other host networks (not VM networks) beside the management one. As an example, migration and storage networks can be defined, each passing dedicated traffic (one for
