Hi, My two cents is that shouldn’t be doing mac spoofing protection as a default. There are several use cases where you may use virtual nics defined withing the guest and this feature is going to create problems to users that may not know that there’s a mac spoofing protection withing ovirt. Think of keeaplived vmac option, openvpn and any tap adapter you need to create. If you need to protect against spoofing attacks, you should use the hook or more powerful tools and in any case, you must be aware that you used this kind of protection. Regards,

vlan-tagging on non-tagged network
by Felix Pepinghege 19 Aug '15

19 Aug '15

Hi everybody! I am experiencing a behaviour of ovirt, of which I don't know whether it is expected or not. My setup is as follows: A virtual machine has a logical network attached to it, which is configured without vlan-tagging and listens to the name 'trunk'. The VM is running an openvpn server. It is a patched openvpn version, including vlan-tagging. That is, openvpn clients get a vlan tag. This should not really be an issue but should satisfy the "why do you want to do it in the first place"-questions. Anyhow, effectively, the VM simply puts vlan-tagged ethernet-frames on the virtual network. These frames, however, never make it to the host's network bridge, which represents the logical network. My observations are: According to tcpdump, the vlan-tagged packages arrive at the "eth1"-interface inside the VM (which *is* the correct interface). Again, according to tcpdump, these packages never arrive at the corresponding network-bridge (i.e., the interface 'trunk') on the host. I know that the setup itself is feasible with KVM---I have it working on a proxmox-machine. Therefore, my conclusion is, that ovirt doesn't like vlan-tagged ethernet-frames on non-tagged logical networks, and somehow filters them out, though I don't really see on what "level" that would happen (Handling the ethernet frames should be a concern of KVM/QEMU/Linux only, once ovirt has started the VM). So this problem could be a CentOS issue, but I really don't see why CentOS should act differently than debian does (proxmox is debian-based). Is this a known/wanted/expected behaviour of ovirt, and can I somehow prevent or elude it? Any help is much appreciated! Of course I am happy to provide more information if that helps helping me :) Regards, Felix

This has happened twice now, these messages start spewing into the both /var/log/messages and /var/log/vdsm/vdsm.log with slightly different formats but the same information. Restarting vdsmd fixes this but I'l like to find why it gets into this state. CentOS 6.7 oVirt 3.5. Any ideas?

live migration
by Demeter Tibor 18 Aug '15

18 Aug '15

Hi, I reinstalled one of my nodes (node1) because I have to replace my hdds. I installed centos 6.6 minimal, but on node re-adding procecure it installed newer qemu-kvm-rhev packages. Since reinstall I can run VMs on this node and I can do live migrate from this node to other, but not backwards. I remember, maybe one years ago it was required to install redhat's version of qemu-kvm-rhve package for this feature. Is it necessary yet? my versions: node0 KVM: 0.12.1.2 - 2.415.el6_5.14, LIBVIRT: libvirt-0.10.2-46.el6_6.1 node1 KVM: 0.12.1.2 - 2.448.el6_6.4, LIBVIRT: libvirt-0.10.2-54.el6 node2 KVM: 0.12.1.2 - 2.448.el6_6.4, LIBVIRT: libvirt-0.10.2-46.el6_6.1 Can I upgrade manual these hosts? I haven't restart my hosts because node0 and node2 is gluster replicate. Thanks in advance, Tibor

upgrade issues

Hi All, I have to upgrade ovirt 3.5.0 to 3.5.3. We have a 3 node system and we have a gluster replica beetwen 2 node of these 3 servers. I had gluster volume beetwen node0 and node2 But I wanted to do a new volume beetwen node1 and node2. It didn't work, it complety kill my node1, because glusterd does not stated.I always have to got always error: gluster peer rejected (related to node1). I followed this article http://www.gluster.org/community/documentation/index.php/Resolving_Peer_Rej… and it was good, my gluster service already worked, but ovirt got these errors Detected deletion of volume g2sata on cluster r710cluster1, and deleted it from engine DB. Detected deletion of volume g4sata on cluster r710cluster1, and deleted it from engine DB. And ovirt does not see my gluster volumes anymore. I've checked with gluster volume status and gluster volume heal g2sata info, it seems to be working, my VMs are ok. How can I reimport my lost volumes to ovirt? Thanks in advance, Tibor

R: vlan-tagging on non-tagged network

--_000_06wqhiuiyku9vk7vukt2dtor1439845594308emailandroidcom_ Content-Type: text/plain; charset="iso-8859-2" Content-Transfer-Encoding: quoted-printable Sorry for jumping into the discussion, but I'm currently experiencing exac= tly the opposite behaviour. DHCP offer is reached until the host bridge interface, but it is not propa= gated to the vnet device. I'm using VLAN tagging. Packets incoming are correctly managed until vnet d= evice and seems to have impact only into DHCP packets. Static IP assigned to the vm =E5eave VM active and reachable. Just my cent to a topic that I suppose could be related to mine issue. Roberto -------- Messaggio originale -------- Da: Felix Pepinghege <pepinghege(a)ira.uka.de> Data: 17/08/2015 13:36 (GMT+01:00) A: Users(a)ovirt.org Oggetto: Re: [ovirt-users] vlan-tagging on non-tagged network Hi Ido, hi everybody, sorry that I kept you waiting for two months, I only just found the time to go back to this problem. You were completely right with your guess. The ethernet frames do appear on the vnet-interface, but not on the bridge. The dropped-counter seems to be independent from these losses, though. However, while this tells me *where* the problem is, I still don't know *what* the problem is. I've done some research, but couldn't find anything particularly helpful. An interesting point may be that this problem is mono-directional. That is, the bridge happily passes vlan-tagged frames from the ethernet device to the vnet, but not the other way around. Untagged ethernet frames make their way through the brigde, no matter where they come from. The vlan module is loaded, as to the versioning questions: # cat /etc/centos-release ; uname -s -v -r CentOS Linux release 7.1.1503 (Core) Linux 3.10.0-229.7.2.el7.x86_64 #1 SMP Tue Jun 23 22:06:11 UTC 2015 The guest OS is an up-to-date Debian Jessie, which should not matter, though, as the frames get lost on the doorstep of the bridge on the host.
