Re: [ovirt-users] vlan-tagging on non-tagged network
Hi again, I just found the reason for the loss of the packages. Either ovirt or centos install some ebtables rules in the nat table. These rules filter ARP packages coming from vnet interfaces. Flushing the table solved my problems. However, I have no idea what the purpose of these rules is, so there might be unwanted side-effects to just flushing the rules away.. But for now I am happy!

Re: [ovirt-users] problem with iSCSI/multipath.
- Original Message - From: Giorgio Bersano giorgio.bers...@gmail.com To: users@ovirt.org Users@ovirt.org Sent: Monday, July 27, 2015 1:19:23 PM Subject: [ovirt-users] problem with iSCSI/multipath. 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. Hi Giorgio, There were some issues related to ISCSI multipathing that were already solved on later versions then 3.4 AFAIK. I'm attaching Sergey and Maor (the feature owners) to respond whether related fixes were made. thanks, Liron. --- 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

[ovirt-users] R: vlan-tagging on non-tagged network
Sorry for jumping into the discussion, but I'm currently experiencing exactly the opposite behaviour. DHCP offer is reached until the host bridge interface, but it is not propagated to the vnet device. I'm using VLAN tagging. Packets incoming are correctly managed until vnet device and seems to have impact only into DHCP packets. Static IP assigned to the vm ĺeave 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 pepingh...@ira.uka.de Data: 17/08/2015 13:36 (GMT+01:00) A: Users@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. Again, any suggestions are much appreciated! Regards, Felix Am 16.06.2015 um 08:27 schrieb Ido Barkan: Hey Felix. IIUC your frames are dropped by the bridge. Ovirt uses Linux Bridges To connect virtual machines to 'networks'. The guest connects to the bridge using a tap device which usually is called 'vnetnumber'. So, just to verify, can you please tcpdump both on the bridge device and on the tap device? The bridge can be quite noisy so I suggest filtering traffic using the guest's MAC address. So I am not sure what protocol you use for tunneling but applying a filter similar to this one should do the job: tcpdump -n -i vnet0 -vvv -s 1500 'udp[38:4]=0x001a4aaeec8e' My guess is that you will observe traffic on the tap device, but not on the bridge. You didn't specify which centOS version you use but I do remember seeing people complaining about Linux bridges discarding their tagged frames. You can -maybe- also observe the 'dropped' counter increases on the bridge by running: 'ip -s link show dev trunk' There were a few bugs on rhel6/7 about this, specifically I remember https://bugzilla.redhat.com/show_bug.cgi?id=1174291 and https://bugzilla.redhat.com/show_bug.cgi?id=1200275#c20 Also, is the vlan module loaded on your host?

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

I followed this article http://www.gluster.org/community/documentation/index.php/Resolving_Peer_Rejected 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?

Re: [ovirt-users] Gluster Replica 3 using arbiter node?
On 07/30/2015 08:11 PM, Adrian Lewis wrote: 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? We currently do not have support for creating a volume with an arbiter node from oVirt, changes are required in the Add Volume flow to enable it. I've opened a BZ to track but will not be available in oVirt 3.6 (https://bugzilla.redhat.com/show_bug.cgi?id=1254073) If you want to use such a volume to be used as storage domain, you will need to create the volume outside of oVirt using gluster cli commands - this has not yet been integrated and tested with the hosted engine flow. Your feedback is welcome.

[ovirt-users] Hosted Engine and Sanlock
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?

Re: [ovirt-users] error adding node.
Hi, I hope i can explain properly ;) (my english isnt that good). This is the situation: 1. We installed a clean install of centos 7 on the host 2. We created an glusterfs share on the host for the engine 3. We ran hosted-engine --deploy and followed the wizard 4. we get the message to open the VNC connection to install the engine (we use centos 6.7 for the engine) 5. We continue the wizard and get the new vnc connection to install the engine 6. When the engine is running the wizard tries to add the host to the engine and then we get the error that he cannot connect to the engine. (we did get the health ok message. The hosts file and dns servers are working correctly. 7. We try to add manually the host to the engine because if the wizard stops at that point he cannot try again because there is already an vm running. 8. When we try to add the host via the engine we get the same error message. The one that he cannot connect to the host. When i try to ssh via the console on the engine to the host it works. What i fing strange is that he almost immidiatly gives the message (within 3 seconds). I hope this explains the steps we took.
