ovirt-shell and PAGER
by Fabrice Bacchella 20 Aug '15

20 Aug '15

ovirt shell uses PAGER for all output, even single line one. I was using PAGER=less, it made it barely usable. That's strange any way for a interactive shell.

Re: [ovirt-users] vlan-tagging on non-tagged network

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

Benefits of Cluster separation

error messages filling disk

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
by Demeter Tibor 18 Aug '15

18 Aug '15

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.

Hosted Engine and Sanlock
by xJutsu Team 17 Aug '15

17 Aug '15

Hi there, recently there was a network failure in our ovirt infrastructure, causing ovirt engine to become unstable. It will restarted after 10-20minutes. Load average was high. Command issued will hanged. Looking at host logs, there was endless locking errors (/var/log/sanlock.log) below. I tried to re-initialize by stopp HE HA agent/broker in all hosts, by issuing following command in one of the host: # su - vdsm -s /bin/bash $ sanlock direct init -s hosted-engine:0:/rhev/data-center/mnt/192.168.10.10 \\:_engine/a184f8ac-b779-4bf8-81c3-751115e15436/ha_agent/hosted-engine.lockspace:0 and than restart both agent and broker in the same host. However i m still getting the same problem. Any advice on this matter?

stuck hosts - how can I delete them?
by Chris Liebman 17 Aug '15

17 Aug '15

I've just force deleted a DC. I did this because gluster was completely hosed. Multiple nodes with broken disks - don't ask... Anyway - now I see that the Cluster still exists with the hosts. And I cant remove, re-install etc the hosts, nor can I delete the cluster. Help! -- Chris

problem with iSCSI/multipath.
by Giorgio Bersano 17 Aug '15

17 Aug '15

Hi all. We have an oVirt cluster in production happily running from the beginning of 2014. It started as 3.3 beta and now is Version 3.4.4-1.el6 . Shared storage provided by an HP P2000 G3 iSCSI MSA. The storage server is fully redundant (2 controllers, dual port disks, 4 iscsi connections per controller) and so is the connectivity (two switches, multiple ethernet cards per server). >From now on lets only talk about iSCSI connectivity. The two oldest server have 2 nics each; they have been configured "by hand" setting routes aimed to reach every scsi target from every nic. On the "new" server we installed ovirt 3.5 to have a look at the network configuration provided by oVirt. In Data Center -> iSCSI Multipathing we defined an iSCSI Bond binding together 3 server's nics and the 8 nics of the MSA. The result is a system that has been functioning for months. Recently we had to do an upgrade of the storage firmware. This activity uploads the firmware to one of the MSA controllers then reboots it. Being successful this is repeated on the other controller. There is an impact on the I/O performance but there should be no problems as every "volume" on the MSA remains visible on other paths. Well, that's the theory. On the two "hand configured" hosts we had no significant problems. On the 3.5 host VMs started to migrate due to storage problems then the situation got worse and it took more than an hour to bring again the system to a good operating level. I am inclined to believe that the culprit is the server's routing table. Seems to me that the oVirt generated one is too simplistic and prone to problems in case of connectivity loss (as in our situation or when you have to reboot one of the switches). Anyone on this list with strong experience on similar setup? I have included below some background information. I'm available to provide anything useful to further investigate the case. TIA, Giorgio. ------------------- context information ------------------- oVirt Compatibility Version: 3.4 two FUJITSU PRIMERGY RX300 S5 hosts CPU: Intel(R) Xeon(R) E5504 @ 2.00GHz / Intel Nehalem Family OS Version: RHEL - 6 - 6.el6.centos.12.2 Kernel Version: 2.6.32 - 504.16.2.el6.x86_64 KVM Version: 0.12.1.2 - 2.448.el6_6.2 LIBVIRT Version: libvirt-0.10.2-46.el6_6.6 VDSM Version: vdsm-4.14.17-0.el6 RAM: 40GB mom-0.4.3-1.el6.noarch.rpm ovirt-release34-1.0.3-1.noarch.rpm qemu-img-rhev-0.12.1.2-2.448.el6_6.2.x86_64.rpm qemu-kvm-rhev-0.12.1.2-2.448.el6_6.2.x86_64.rpm qemu-kvm-rhev-tools-0.12.1.2-2.448.el6_6.2.x86_64.rpm vdsm-4.14.17-0.el6.x86_64.rpm vdsm-cli-4.14.17-0.el6.noarch.rpm vdsm-hook-hostusb-4.14.17-0.el6.noarch.rpm vdsm-hook-macspoof-4.14.17-0.el6.noarch.rpm vdsm-python-4.14.17-0.el6.x86_64.rpm vdsm-python-zombiereaper-4.14.17-0.el6.noarch.rpm vdsm-xmlrpc-4.14.17-0.el6.noarch.rpm # ip route list table all |grep 192.168.126. 192.168.126.87 dev eth4 table 4 proto kernel scope link src 192.168.126.65 192.168.126.86 dev eth4 table 4 proto kernel scope link src 192.168.126.65 192.168.126.81 dev eth4 table 4 proto kernel scope link src 192.168.126.65 192.168.126.80 dev eth4 table 4 proto kernel scope link src 192.168.126.65 192.168.126.77 dev eth4 table 4 proto kernel scope link src 192.168.126.65 192.168.126.0/24 dev eth4 table 4 proto kernel scope link src 192.168.126.65 192.168.126.0/24 dev eth3 proto kernel scope link src 192.168.126.64 192.168.126.0/24 dev eth4 proto kernel scope link src 192.168.126.65 192.168.126.85 dev eth3 table 3 proto kernel scope link src 192.168.126.64 192.168.126.84 dev eth3 table 3 proto kernel scope link src 192.168.126.64 192.168.126.83 dev eth3 table 3 proto kernel scope link src 192.168.126.64 192.168.126.82 dev eth3 table 3 proto kernel scope link src 192.168.126.64 192.168.126.76 dev eth3 table 3 proto kernel scope link src 192.168.126.64 192.168.126.0/24 dev eth3 table 3 proto kernel scope link src 192.168.126.64 broadcast 192.168.126.0 dev eth3 table local proto kernel scope link src 192.168.126.64 broadcast 192.168.126.0 dev eth4 table local proto kernel scope link src 192.168.126.65 local 192.168.126.65 dev eth4 table local proto kernel scope host src 192.168.126.65 local 192.168.126.64 dev eth3 table local proto kernel scope host src 192.168.126.64 broadcast 192.168.126.255 dev eth3 table local proto kernel scope link src 192.168.126.64 broadcast 192.168.126.255 dev eth4 table local proto kernel scope link src 192.168.126.65 one HP ProLiant DL560 Gen8 host CPU: Intel(R) Xeon(R) CPU E5-4610 v2 @ 2.30GHz / Intel SandyBridge Family OS Version:RHEL - 6 - 6.el6.centos.12.2 Kernel Version: 2.6.32 - 504.16.2.el6.x86_64 KVM Version: 0.12.1.2 - 2.448.el6_6.2 LIBVIRT Version: libvirt-0.10.2-46.el6_6.6 VDSM Version: vdsm-4.16.14-0.el6 RAM: 256GB mom-0.4.3-1.el6.noarch.rpm ovirt-release35-002-1.noarch.rpm qemu-img-rhev-0.12.1.2-2.448.el6_6.2.x86_64.rpm qemu-kvm-rhev-0.12.1.2-2.448.el6_6.2.x86_64.rpm qemu-kvm-rhev-tools-0.12.1.2-2.448.el6_6.2.x86_64.rpm vdsm-4.16.14-0.el6.x86_64.rpm vdsm-cli-4.16.14-0.el6.noarch.rpm vdsm-hook-hostusb-4.16.14-0.el6.noarch.rpm vdsm-hook-macspoof-4.16.14-0.el6.noarch.rpm vdsm-jsonrpc-4.16.14-0.el6.noarch.rpm vdsm-python-4.16.14-0.el6.noarch.rpm vdsm-python-zombiereaper-4.16.14-0.el6.noarch.rpm vdsm-xmlrpc-4.16.14-0.el6.noarch.rpm vdsm-yajsonrpc-4.16.14-0.el6.noarch.rpm # ip route list table all |grep 192.168.126. 192.168.126.0/24 dev p6p1 proto kernel scope link src 192.168.126.34 192.168.126.0/24 dev p3p1 proto kernel scope link src 192.168.126.33 192.168.126.0/24 dev em3 proto kernel scope link src 192.168.126.32 local 192.168.126.32 dev em3 table local proto kernel scope host src 192.168.126.32 local 192.168.126.33 dev p3p1 table local proto kernel scope host src 192.168.126.33 broadcast 192.168.126.0 dev p6p1 table local proto kernel scope link src 192.168.126.34 broadcast 192.168.126.0 dev p3p1 table local proto kernel scope link src 192.168.126.33 broadcast 192.168.126.0 dev em3 table local proto kernel scope link src 192.168.126.32 local 192.168.126.34 dev p6p1 table local proto kernel scope host src 192.168.126.34 broadcast 192.168.126.255 dev p6p1 table local proto kernel scope link src 192.168.126.34 broadcast 192.168.126.255 dev p3p1 table local proto kernel scope link src 192.168.126.33 broadcast 192.168.126.255 dev em3 table local proto kernel scope link src 192.168.126.32

ovirt 3.5.2 issues with nodes becoming "Non Operational"
by Chris Liebman 17 Aug '15

17 Aug '15

Hi, I'm new to oVirt and recently built a 10 node ovirt 3.5 DC with shared storage using gluster configured as distributed-replicated (replication = 2). Shortly after 7 of the 10 nodes dropped, one at a time over a few hours, into "Non Operational" state. Attempting to activate one of these nodes gives the error: "Failed to connect Host ovirt-node260 to Storage Pool LADC-TBX". Attempting to put the node into Maintenance eaves the node stuck in "Preparing For maintenance". When I rebooted one of the nodes I see this in the nodes event list: "Host ovirt-node269 reports about one of the Active Storage Domains as Problematic." I see many of these errors in the vdsm log from the failed nodes: Thread-10000::ERROR::2015-08-12 > 10:01:17,748::__init__::506::jsonrpc.JsonRpcServer::(_serveRequest) > Internal server error > > Traceback (most recent call last): > > File "/usr/lib/python2.6/site-packages/yajsonrpc/__init__.py", line 501, > in _serveRequest > > res = method(**params) > > File "/usr/share/vdsm/rpc/Bridge.py", line 267, in _dynamicMethod > > result = fn(*methodArgs) > > File "/usr/share/vdsm/API.py", line 1330, in getStats > > stats.update(self._cif.mom.getKsmStats()) > > File "/usr/share/vdsm/momIF.py", line 60, in getKsmStats > > stats = self._mom.getStatistics()['host'] > > File "/usr/lib/python2.6/site-packages/mom/MOMFuncs.py", line 75, in > getStatistics > > host_stats = self.threads['host_monitor'].interrogate().statistics[-1] > > AttributeError: 'NoneType' object has no attribute 'statistics' > Any help here is appreciated. -- Chris

Gluster Replica 3 using arbiter node?
by Adrian Lewis 17 Aug '15

17 Aug '15

Hi, Just wondering if it will be possible to create gluster replica 3 volumes in oVirt 3.6 that use the arbiter function instead of actually storing three copies of the data? If so, could this be used for the hosted engine on gluster feature which from what I can tell requires replica 3? Many thanks, Adrian

CPU Threads Help!!!

--------------020500020201060207010309 Content-Type: text/plain; charset="UTF-8"; format=flowed Content-Transfer-Encoding: 8bit Hi, Guys Recently I am investigating the Optimization Policy in Cluster and try to use “CPU Threads”. As the manual of description: ======== For example, a 24-core system with 2 threads per core (48 threads total) can run virtual machines with up to 48 cores each ======== My host CPU is i3-2120 CPU (2 cores 4 threads) So I think the expect result case is : 1. If the “Count Threads As Cores” *disable*, we can’t run virtual vm with above 2 vCPU 2. If the “Count Threads As Cores” *enable*, we can’t run virtual vm with above 4 vCPU Now the problem is about result case 1: 1. When I set “Count Threads As Cores” *disable*, I still can run virtual vm with 4 vCPU Can anyone help me to explain it ???

Stuck installing Neutron Appliance
by Alan Murrell 16 Aug '15

16 Aug '15

Hello. I am running oVirt 3.5.1. on a single server running Hosted Engine. I am running through <http://www.ovirt.org/Features/NeutronVirtualAppliance#Run_the_neutron_serve…> and am stuck on the section "Install a Host with the network provider". Specifically, I am stuck on Step 2, which is: 2. Install the host with the external network provider by clicking on the 'Network Provider' left tab I am not sure where to click. In my "Tree", I do have "External providers", but I already added my Neutrom Provider in the previous section, 'Configure Neutron network provider on ovirt-engine'. Is there somewhere else I need to add this, or because I am running a self-hosted engine, it ends up being the same thing? Also in this same section, Step 7 where I am to run 'ovs-vsctl add-port br-neutron neutron', I don't have this command ('ovs-vsctl' doesn't seem to be installed, which I believe is part of openVswtich). I didn't see any steps beforehand that would have installed openVswitch. Is there a step missing? Thanks! :-) Regards, Alan
