Dedicated NICs for gluster network
by Nicolas Ecarnot 22 Aug '16

22 Aug '16

Hello, [Here : oVirt 3.5.3, 3 x CentOS 7.0 hosts with replica-3 gluster SD on the hosts]. On the switchs, I have created a dedicated VLAN to isolate the glusterFS traffic, but I'm not using it yet. I was thinking of creating a dedicated IP for each node's gluster NIC, and a DNS record by the way ("my_nodes_name_GL"), but I fear using this hostname or this ip in oVirt GUI host network interface tab, leading oVirt think this is a different host. Not being sure this fear is clearly described, let's say : - On each node, I create a second ip+(dns record in the soa) used by gluster, plugged on the correct VLAN - in oVirt gui, in the host network setting tab, the interface will be seen, with its ip, but reverse-dns-related to a different hostname. Here, I fear oVirt might check this reverse DNS and declare this NIC belongs to another host. I would also prefer not use a reverse pointing to the name of the host management ip, as this is evil and I'm a good guy. On your side, how do you cope with a dedicated storage network in case of storage+compute mixed hosts? -- Nicolas ECARNOT

Suddenly all VM's down including HostedEngine & NFSshares (except HE) unmounted
by Matt . 22 Aug '16

22 Aug '16

HI All, I'm trying to tackle an issues on 4.0.2 that sunddenly all VM's including the HostedEngine are just down at once. I have also seen that all NFS shares are unmounted except the HostedEngine Storage, which is on the same NFS device as well. I have checked the logs, nothing strange to see there, but as I run a vrrp setup and do some tests also I wonder if there is a duplicate IP brought up, could this make happen the whole system to go down and the Engine or VDSM unmounts the NFS shares ? My switches don't complain. It's strange that the HE share is only available after it happens. If so, this would be quite fragile and we should tackle where it goes wrong. Anyone seen this bahaviour ? Thanks, Matt

Cannot resolve prinicpal 'user@corp.domain.com' after attaching AD to ovirt-engine
by Danny Rehelis 21 Aug '16

21 Aug '16

Hi, After successfully attaching ovirt-engine 4.0.2.6-1.el7 to corporate AD, I'm unable to login using just 'user'. When typing 'user(a)domain.com' it works. Is this behavior by design? Cheers,

3.6 : VLAN / non VLAN
by Alexis HAUSER 21 Aug '16

21 Aug '16

hi, I'd like to know what happens when you create a new network, tagged with VLAN for example 25 and using em2 : - the packets outgoing from em2.25 are tagged, right ? - the packets outgoing from em2 are tagged or not ? - the result is packets inside ovirt are tagged, but when you go out of it and reach something from em2, are the packets still tagged ?

Ovirt-Engine HA
by Sandvik Agustin 19 Aug '16

19 Aug '16

Hi Ovirt Users, Do you have any documentation, tutorial, howto or workaround to perform or to have an ovirt-engine HA? Iv'e tried to google about this but I can't find any. let's say I want to have two engine, engine1 is currently managing two hypervisor, then engin2 is my reserved engine, so I can still managed those vm that are running inside of my hypervisor if ever engine1 fails. TIA :) Sandvik

HostedEngine NIC setup files
by Hanson 19 Aug '16

19 Aug '16

Hi Guys, I have edited /etc/sysconfig/network-scripts/ifcfg-eth0 &1 for the various subnets we needed. Somewhere along the line, when the hosted-engine boots, eth1 comes up but eth0 does not. If I login using the upped interface and do an ifup eth0 it comes up. it is set to ONBOOT=yes in the config. I know with the nodes, that these files are overwritten on boot. Where should I be editing for the hosted-engine? Thanks, Hanson

3.5 / 3.6 stuck
by Erik Brakke 19 Aug '16

19 Aug '16

Hello, I changed my cluster and data center compatibility from 3.5 to 3.6 with a 3.5 host. D'oh! Engine: 3.6 on FC22 Host: 3.5 on FC22 (local storage) - Can I change the data center and cluster back to 3.5? How? - I tried to upgrade host to 3.6 in the GUI. Maintenance->Reinstall did not work, and Upgrade option is greyed out. Is there a way to upgrade host to 3.6? Thanks

Cannot start hosted engine after last 4.0.1 packages
by Matt . 19 Aug '16

19 Aug '16

Hello, I'm having issues after the last 4.0.1 package just before 4.0.2 came out. My engine was running great, hosts started the vm also and the hosted-engine command was working fine. Now I get rpcxml 3.6 deprecated warning which I never got before. See the attachment for this output. I have checked is IPv6 was disabled, but it isn't as that is what is needed for this. Any clue ? Thanks! Matt

Is hosted engine supported in hosts with diff CPU types?
by Fredy Sanchez 18 Aug '16

18 Aug '16

Hi all, I am deploying hosted engine in what will hopefully become our 4th oVirt cluster. The engine is up and running happily in host 1 already, but I am running into the following when running hosted-engine --deploy in hosts 2 and 3: The following CPU types are supported by this host: - model_Opteron_G3: AMD Opteron G3 - model_Opteron_G2: AMD Opteron G2 - model_Opteron_G1: AMD Opteron G1 [ ERROR ] Failed to execute stage 'Environment customization': Invalid CPU type specified: model_SandyBridge Host 1 has an Intel chip. Hosts 2 and 3 have an AMD chip. Is this a supported config? If so, how can I bypass the error? Thank you very much. Cheers, Fredy

I am running 4.0 on CentOS 7.2. Sometimes when I first log in to the admin page, it will give me and error that says "Request state does not match session state." Then if I go through the process of logging in again, it will go through with no issue. It doesn't do this every time but it does do it quite often. Any ideas on why? - MeLLy

Upgrade hosts/nodes from engine
by Hanson 17 Aug '16

17 Aug '16

Hi Guys, Quick question, I have my nodes on a bond-bridge-privateVlan setup, and my engine on a bond-bridge-publicVlan setup for remote monitoring. Understandably, the nodes are complaining that they are failing updates. (They're on a private vlan, and only configured with IP's in that vlan, the public vlan doesn't have IP's set on the hosts so they can pass it to VMs). Is there a way to have the engine do the updates on the node using its internet connection, like a proxy? For security reasons I like to have the nodes not publicly accessible, as we see hundreds if not thousands of ssh attempts, and root would probably be the most attacked account. Thanks, Hanson

Team, I got two oVirt Servers. One in 4.0.2 and one in 3.6.X I love the new 4.0 dashboard, But I need a way to continue to build reports with ease, 3.6 Can do this with ovirt-reports. How can I make my oVirt 4.0.2 send data for reports to my ovirt reports on 3.6? Thanks for the help team! Regards, -- Fernando Fuentes ffuentes(a)txweather.org http://www.txweather.org

Gluster replication on 1Gb interfaces
by Fernando Frediani 16 Aug '16

16 Aug '16

Hi all. I understand using 10Gb interfaces when using Gluster is advised for helping with data replication specially in situations where a node went down for a while and need to re-sync data. However can anyone tell if using one 1Gb interface dedicated for it in hosts with 1.8 TB of Raw storage would be still Ok or can it cause severe impact on performance ? What are the chances of a 1Gb nice being saturated during normal operation ? Thanks Fernando

edit gluster storage domain
by Edward Clay 16 Aug '16

16 Aug '16

Hello, I need to edit a glusterfs storage domain to add the mount option " backupvolfile-server=SERVER" So when the primary servers IP is not accessible the remaining servers will be used to retrieve data stored on the gluster volume. Right now when I try to edit the storage domain the mount options box is grayed out and not editable. I recently had to take all vms down so I put the HV in maintenance mode and the edit options wasn't present. I need to understand if this is the correct option to make a glusterfs volume fault tolerant? Also I need to understand how to make this edit in the ovirt web interface or other method. TIA

oVirt 4 with custom SSL-certificate and SPICE HTML5 browser client -> WebSocket error: Can't connect to websocket on URL: wss://ovirt.engine.fqdn:6100/

Hello oVirt guru`s ! I have successfully replaced the oVirt 4 site SSL-certificate according to the instructions from "Replacing oVirt SSL Certificate" section in "oVirt Administration Guide" http://www.ovirt.org/documentation/admin-guide/administration-guide/ 3 files have been replaced: /etc/pki/ovirt-engine/certs/apache.cer /etc/pki/ovirt-engine/keys/apache.key.nopass /etc/pki/ovirt-engine/apache-ca.pem Now the oVirt site using my certificate and everything works fine, but when I try to use SPICE HTML5 browser client in Firefox or Chrome I see a gray screen and message under the button "Toggle messages output": WebSocket error: Can't connect to websocket on URL: wss://ovirt.engine.fqdn:6100/eyJ...0=[object Event] Before replacing certificates SPICE HTML5 browser client works. Native SPICE client works fine. Tell me what to do with SPICE HTML5 browser client?
