"bridge port" error when setting up hosted-engine on 2nd oVirt 3.6.2 node
by Mike DePaulo 18 Feb '16

18 Feb '16

Hi, I am getting the following error when I attempt to setup my 2nd ovirt node as a hosted-engine: RuntimeError: The selected device None is not a supported bridge port The 1st node is death-star (192.168.1.50) The 2nd node is starkiller-base (192.168.1.52) This is not a production environment; this is my apartment. I am able to access the engine's webGUI. Both death-star and starkiller-base start out with only eno1 as their only NIC. death-star, by the end of the hosted-engine-setup, had ovirtmgmt also (with the same MAC address.) starkiller-base does not have ovirtmgmt yet. I am not using VLANs. node version: ovirt-node-iso-3.6-0.999.201602121021.el7.centos.iso engine appliance version: oVirt-Engine-Appliance-CentOS-x86_64-7-20160126.ova Thanks in advance, -Mike

ovirt and gluster storage domain HA testing
by Bill James 17 Feb '16

17 Feb '16

I have a ovirt cluster with and system running ovirt-engine 3.6.2.6-1 on centos7.2 and 3 hardware nodes running glusterfs 3.7.6-1 and centos7.2. I created a gluster volume using gluster cli and then went to add a storage domain. I created it with Path ovirt1-ks.test:/gv1 and all works fine, until ovirt1 goes down. Then ALL VMs pause till ovirt1 comes back up. Do I have to list all nodes in the path for this to work? Path: ovirt1-ks.test:/gv1 ovirt2-ks.test:/gv1 ovirt3-ks.test:/gv1 Or how do I prevent ovirt1 from being single point of failure? Thanks.

Understanding direct lun connection: iscsi pass through disks
by Arman Khalatyan 17 Feb '16

17 Feb '16

Hi, I am trying to combine performance and virtualisation with direct iscsi disks . Assuming we have vm with /dev/vda for OS two data disks from iscsi01:/dev/sda and iscsi02:/dev/sdb direct lun disks configured over ovirt interface. The iscsi disks are used as zfs mirror inside the vm. When one of the iscsi disks is not available then the whole host goes into pause state. Are there way to force ovirt do not freeze vm if direct lun is away? Thanks, Arman

Pending events in the Tasks tab
by nicolas＠devels.es 17 Feb '16

17 Feb '16

Hi, We're using oVirt 3.6.2.6, and we're having some events not being cleared from the Tasks tab. I cannot confirm this is only related to creating VM pools, but any created VM pool remains unfinished forever in the Tasks tab. As you may see in the screenshot, there are events that were started in January and are still in the list. Concretely, the unfinished step is always "Finalizing". Has this been reported on Bugzilla? Is there a way to clear them out even manually? Thanks. Nicolás

oVirt 3.6.2 issue when updating to gluster 3.7.8
by Luiz Claudio Prazeres Goncalves 17 Feb '16

17 Feb '16

Hi, I realised that gluster 3.7.8 was released for GA. So I updated manually using "yum -y install glusterfs*" gluster get's updated normally, but unfortunately things stopped to work completely. ovirt_hosted_engine_ha was not able to connect to my gluster storage domain (as you can see below). I'm not using ovirt + gluster in hyperconverged way. I have 3 external gluster hosts. As a workaround I've executed "*yum* downgrade glusterfs*" and after doing this ovirt started to work again...but as a collateral effect now I can't migrate my vm's anymore. On the vdsm logs I can see the following errors when trying to manually migrate a any VM.... Anyone knows how to fix it?

[Node] Maintenance mode and update
by Lionel Caignec 17 Feb '16

17 Feb '16

Hello, I am concerned about maintenance mode and system updates. In which case it is essential to put host in maintenance mode? No worries for Content Updates requiring a reboot. But for example in the case of updates like VDSM* or kvm it seems essential, but is it? -- Lionel
