Suddenly all VM's down including HostedEngine & NFSshares (except HE) unmounted
by Matt . 21 Aug '16

21 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

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 20 Aug '16

20 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 ?

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
