[Ovirt 4.0] HA VM fail to start on another Host.
by TranceWorldLogic . 26 Apr '17

26 Apr '17

Hi, This is regarding HA VM fail to restart on other host. I have setup, which has 2 host in a cluster let say host1 and host2. And one HA VM (with High priority), say vm1. And also not storage domain is configure on host3 and it available all time. 1> Initially vm1 was running on host2. 2> Then I power OFF host2 to see whether ovirt start vm1 on host1. I found two result in this case as below: 1> Sometime vm1 retrying to start but retrying on host2 itself. 2> Sometime vm1 move in down state without retrying. Can anyone explain about this behaviour ? Or Is this an issue ? Note : I am using Ovirt 4.0. Thanks, ~Rohit

ovirt minor upgrades for nodes via GUI or CLI?
by Matthias Leopold 26 Apr '17

26 Apr '17

hi, i'm still testing ovirt 4.1. i installed engine and 2 nodes in vanilla centos 7.3 hosts with everything that came from http://resources.ovirt.org/pub/yum-repo/ovirt-release41.rpm i regularly checked for updates in the engine host OS with "yum update" (is there a gui option for this?). it obviously got an ovirt update from version 4.1.0 to 4.1.1.1 already some time ago. i regularly checked for updates in the nodes via the ovirt web gui (installation - check for upgrade). there where package updates available and installed in the past so i thought that everything was fine. now i checked with "yum check-update" in the nodes OS shell and noticed that ovirt-release41 is still on 4.1.0 and there are 81 packages available for update (from centos base _and_ ovirt repos including ovirt-release41 itself). ovirt gui tells me 'no updates found'. why didn't these updates get installed? is it because of the ovirt-release41 update? do i have to do this manually with yum? thx matthias

Virtual Machines on same host / traffic stays local?
by Devin Acosta 26 Apr '17

26 Apr '17

I just want to confirm if we have oVIRT running say 3 VM's on the same host and the host is configured for bridging would the traffic stay on the host or would it technically hit the switch and back to the host? -- Devin Acosta Red Hat Certified Architect, LinuxStack 602-354-1220 || devin(a)linuxguru.co

[oVirt 4.1] hosted-engine deploy doesen't show teamed cards
by wodel youchi 26 Apr '17

26 Apr '17

Hi, We're deploying a new oVirt 4.1 installation, we used host ISO to deploy the hypervisors. We used the cockpit webui to team two nic cards using 802.3ad LACP protocol, unfortunately the hosted-engine deploy didn't offer the use of that team, it showed the individual cards only. I used the hosted-engine deployment once on 3.6 version using bonding (not teaming), and it was proposed upon deployment. Is configuring teaming before deployment not supported?

Import OVA
by Andy Kress 25 Apr '17

25 Apr '17

All, I am using the latest version of Ovirt 4.1.1.8-1 running in CentOS 7.3 and would like to import an OVA. Since it appears the image-uploader utility is deprecated, does anyone have information on how to accomplish this? I cannot import it through the UI directly and rather than importing the OVA to a VMWARE environment and pulling it in, I would like to know how to directly do this. Thanks AK

Gluster and oVirt 4.0 questions
by Jim Kusznir 25 Apr '17

25 Apr '17

hello: I've been running my ovirt Version 4.0.5.5-1.el7.centos cluster for a while now, and am now revisiting some aspects of it for ensuring that I have good reliability. My cluster is a 3 node cluster, with gluster nodes running on each node. After running my cluster a bit, I'm realizing I didn't do a very optimal job of allocating the space on my disk to the different gluster mount points. Fortunately, they were created with LVM, so I'm hoping that I can resize them without much trouble. I have a domain for iso, domain for export, and domain for storage, all thin provisioned; then a domain for the engine, not thin provisioned. I'd like to expand the storage domain, and possibly shrink the engine domain and make that space also available to the main storage domain. Is it as simple as expanding the LVM partition, or are there more steps involved? Do I need to take the node offline? second, I've noticed that the first two nodes seem to have a full copy of the data (the disks are in use), but the 3rd node appears to not be using any of its storage space...It is participating in the gluster cluster, though. Third, currently gluster shares the same network as the VM networks. I'd like to put it on its own network. I'm not sure how to do this, as when I tried to do it at install time, I never got the cluster to come online; I had to make them share the same network to make that work. Ovirt questions: I've noticed that recently, I don't appear to be getting software updates anymore. I used to get update available notifications on my nodes every few days; I haven't seen one for a couple weeks now. is something wrong? I have a windows 10 x64 VM. I get a warning that my VM type does not match the installed OS. All works fine, but I've quadrouple-checked that it does match. Is this a known bug? I have a UPS that all three nodes and the networking are on. It is a USB UPS. How should I best integrate monitoring in? I could put a raspberry pi up and then run NUT or similar on it, but is there a "better" way with oVirt? Thanks! --Jim

Windows Server 2016 client licensing costs
by Andrew Wippler 25 Apr '17

25 Apr '17

We have been running oVirt for over two years now and we are quite satisfied with it. Most of our infrastructure is CentOS VMs with about 7 Windows VMs which are all running on 4 oVirt nodes. With Microsoft changing their licensing terms for 2016, it sounds like I have to pay a license fee for the physical hypervisor cores if I intend to run Windows Server 2016 virtual machines on them - even if Windows is not the Host OS. Does this sound about right? Has anyone had to buy 2016 licenses yet? Did you also have to buy licenses to cover the host? What are other hypervisor companies (i.e. VMWare, Citrix, etc.) instructing their customers to do?

There is no way to make a replica volume from a 4 bricks. But you may combine distributed volumes and replica volumes [1]: gluster volume create test-volume replica 2 transport tcp server1:/b1 server2:/b2 server3:/b3 server4:/b4 test-volume would be like a RAID10 - you will have two replica volumes b1+b2 and b3+b4 combined into a single distributed volume. In that case you will have only two copies of your data. Part of your data will be stored twice on b1 and b2 and another one part will be stored twice at b3 and b4 You will be able to extend that distributed volume by adding new replicas.

Of course I needed to restart the database, to change the requested setting about vacuum.

On last friday, I tried a first upgrade, but it stop because of the requested version mismatch. So I stopped it and asked for help. On monday I tried to apply the tuning on my database about autovacuum and so restart it. At this time, ovirt was still working fine. I then upgraded the pg client, to match pg_dump with the server but not the jdbc library, to keep the one supported (9.2). And then it failed and didn't want to restart any more.
