I use glusterfs as storage. When I tried to create a virtual disk for a vm, I got the following error in UI logs.

VDI experience to share?
by Giorgio Bersano 28 Jun '16

28 Jun '16

Hi everyone, I've been asked to deploy a VDI solution based on our oVirt infrastructure. What we have in production is a 3.6 manager (standalone, not HE) with a 3.5 cluster (CentOS 6) and a 3.6 cluster (CentOS 7), iSCSI storage, fully redundant networking. What is not clear to me is the client side, especially because we have been asked to implement a thin client solution but I've been almost unable to find suitable devices. Is there anyone in this list willing to share his/her experience on this topic? Probably my search skill is low but I've only seen references to IGEL. Other brands? There is another strong requirement: our network infrastructure makes use of 802.1x to authenticate client devices and it would be highly advisable to respect that constraint. TIA, Giorgio.

Re: [ovirt-users] 3.6 to 4.0 upgrade cert issue
by Matt Haught 28 Jun '16

So I switched back to the original self-signed certs that I had luckily saved and was able to get in without error. Is there a new process for using non-self-signed certs with ovirt 4.0?

Security Groups
by Pavel Gashev 28 Jun '16

28 Jun '16

Hello, Currently oVirt supports network security groups for OpenStack network provider only. Are there plans to implement Security Groups for native networks? Technically, I can configure a vNic profile with some Security Groups UUID, and apply it in before_device_create and before_update_device VDSM hooks as filterref to some custom nwfilter. The only issue is that I have to manually edit and distribute nwfilter xml among hardware nodes. If I want isolate set of VMs, I have to manually maintain MAC addresses of VMs in that xml. It would be great if oVirt web interface had a nwfilter editor. Are there plans for it? Thanks

migrating a vm from a down node
by Bill James 28 Jun '16

28 Jun '16

I am doing some fault tolerance type testing with ovirt before we put it in production. One thing I noticed is if I unplug the power from a hardware node, including iLo (fence), that the VMs that were on that host go to unknown state. I have found no way in the GUI to migrate the hosts, even they they are marked HA. The only way I've found so far is to modify the database directly. Is that the only recovery from a host failure of this type? engine=> update vm_dynamic set status = 0 where vm_guid =(select engine(> vm_guid from vm_static where vm_name = 'myvm'); ovirt-engine-3.6.4.1-1.el7.centos.noarch centos 7.2 Also is 3.6.4 a OK version to use or should I upgrade first? (looks like 3.6.6.2-1.el7.centos is current latest)

Accessing VM over WAN
by RK RK 28 Jun '16

28 Jun '16

Hi, I am planning to deploy oVirt 4.0.0 in a production environment where initially it will host 150 VDIs and will expand by 20 to 25 in subsequent years with Windows 7, 8.1 and 10. Users will be accessing these VDIs from their android tab or any tiny thin client devices which will have only very small footprint OS with HTML5 supported browser. I wish to give users to access the VDIs over WAN(from their home or on travel). Is it possible to access the VDIs via spice-html5 over the WAN. Any special configurations to be made to enable it? How should I make spice-html5 as the default protocol to access the VDIs? -- With Regards, RK, +91 9840483044

VMs halt on Storage Error
by David Gerner 27 Jun '16

27 Jun '16

Hi, I'm running into a strange issue that I've been trying to solve unsuccessfully for a few days now, and I was hoping someone could offer some insight. A few days ago I needed to reboot the the server that hosts the management engine and is also a node in the system. Following proper procedure I selected a new host to be the SPM, migrated VMs off the Host, and put it into maintenance mode. After the host came back up (and the management engine was back online) I noticed that one of my VMs had halted on a storage error, to rule out the SPM being the issue I asked oVirt to select a new SPM and it was stuck in a contending loop where each host tries to contend for SPM status but ultimately fails (every other VM also halted by this point). The error was "BlockSD master file system FSCK error", after researching the error I found a post on this list that was the same error and the author said that a simple FSCK on the offending file system fixed his issue. I had to force shutdown every VM from the halted state and put all but one host into maintenance mode. On that host I ran a FSCK on the offending volume which found a lot of short read errors which it fixed and afterwards the contending loop was broke and hosts could now successfully be an SPM. Now every VM halts on start or resume, even ones that were offline at the time of the earlier incident, with a Storage Error "abnormal vm stop device virtio-disk0 error eio". I can't even create new disks because it fails with an error. I've attached what I think is the relevant VDSM log portion of a VM trying to resume, if more is needed please just let me know. I'm worried FSCK and I mangled the file system, and have no idea how to repair it. Any insight is greatly appreciated.
