Call for translators: Russian and Czech
by Sandro Bonazzola 20 Nov '18

20 Nov '18

Hi, one of the beta release criteria is that supported languages have translations at least at 70% of completion. According to zanata[1] we currently have Chinese (Simplified, China) (zh-Hans-CN): 95.1% Czech (cs): 33.97% French (fr) 95.1% German (de) 95.1% Italian (it) 85.84% Japanese (ja): 95.1% Korean (ko) 95.1% Portuguese (Brazil) (pt-BR): 95.1% Russian (ru): 25.17% Spanish (es): 95.1% So, right now Czech and Russian are not meeting release criteria for beta release and are candidate to be disabled in 4.3 unless translators pushes the missing parts.

[ovrit-users] Anyone with Fiber Channel oVirt Storage Experience?
by Jacob Green 20 Nov '18

20 Nov '18

I just have a few simple questions, have you migrated a fiber channel storage domain from one ovirt environment to another? And how did it go, did it just work aside from having to import all the vms and configure their settings was it any more difficult than that? We want to migrate our fiber channel storage with VM's intact from an oVirt 4.1 environment to a brand new oVirt 4.2 environment. We are using fiber channel via An HP MSA. I do not for see any issues, but since we have never done it before, and we do not have spare Fiber Channel storage to test with, we are just unsure of what the behavior should be. So just wanted to get some opinions or basic guidance, is there anything we should watch out for and does it "just work". -- Jacob Green Systems Admin 713-300-5690

External VMs automatically deleted when powered down
by andyg1001＠hotmail.co.uk 20 Nov '18

20 Nov '18

Hi, I have a pressing problem with oVirt, which is sadly languishing as a bug report (#1610917), so I thought I would also raise it here in case anyone else has experience of this and can suggest a workaround or, better yet, a solution to my problem :o) Simply put, the problem is this. I have oVirt 4.2.7 installed on a Cent-OS 7.5 server. It is also necessary, due to various factors, to run what oVirt terms "external VMs" on this server, i.e. ones not managed by oVirt but managed separately, e.g. via virt-manager or virsh. The problem is that once these VMs are shut down (e.g. within the VM or by a command from virt-manager), they are automatically deleted by oVirt some 15 seconds later. The bug report noted above has more details, but these VMs are not created as temporary VMs, and when running the older oVirt 4.1.x or 3.8.x versions, this didn't happen. Looking through the oVirt and libvirt logs, it is really clear that oVirt is responsible for deleting these VMs, so I can rule out any other nefarious agent! Does anyone know of a way of preventing oVirt from deleting external VMs, like a special config option or something? Or does anyone know how to mark a VM as "protected from deletion"? I know oVirt VMs have an option for "delete protection", but oVirt gives the error "Cannot edit VM. This VM is not managed by the engine." if you try to enable it on an external VM. Many thanks, Andy

Who are field-service technicians
by sirishanaginip92＠gmail.com 19 Nov '18

19 Nov '18

Those engineers who work on fields and provide on field service are termed as field technicians. For example, consider 3 SWAN deployments. To complete network deployment, telecom engineers should visit the field and as an initial step, they should perform a site survey followed by deployment. The entire process mentioned needs field service, where their physical presence is required, Hence the need for field service technicians is been increased day by day. Here is the useful URL, that helps in finding the telecom freelancers. https://www.fieldengineer.com/

VM stuck in paused mode with Cluster Compatibility Version 3.6 on 4.2 cluster
by Marco Lorenzo Crociani 19 Nov '18

19 Nov '18

Hi, we upgraded ovirt from version 4.1 to 4.2.6. Rebooted all vms. We missed two vms that were at Cluster Compatibility Version 3.6. There was a gluster/network IO problem and vms got paused. We were able to recover all the other vms from the paused state but we have two vms that won't run because: "Cannot run VM. The Custom Compatibility Version of VM VM_NAME (3.6) is not supported in Data Center compatibility version 4.1." Can we force the CCV of the paused vm to 4.1? Regards, -- Marco Crociani

troubleshooting node upgrade failures
by Jayme 19 Nov '18

19 Nov '18

I have a very standard three node HCI setup running the latest version of oVirt 4.2. I've been having some problems updating hosts, the last update that was released a few weeks ago would produce installfailed when updating hosts. I was able to resolve this by rebooting the host first then performing the update. I eventually got all three hosts updated. Fast forward to this week, a new update is available. I've updated engine successfully but first host, I put in to maintenance then updated and the install is failing. I've rebooted it twice and attempted update again but no go this time. What logs should I be looking at to determine what is causing the node update failures?

How to do per-datacenter/cluster permissions?
by nyhagen＠sedsystems.ca 19 Nov '18

19 Nov '18

Hello! I'm evaluating oVirt for our company, and one thing we need to verify is that users only have access to virtual machines/clusters that they should have access to. I have the users set up from LDAP, and I added the UserRole to them, however it seems like they, by default, have access to every VM available. How do I go about limiting what VMs they have access to? I'd assume I'd have to limit access on a datacenter or cluster level, but I can't seem to find any documentation as to how to do this.

Error start VM with "XML: Multiple 'scsi' controllers with index '0' " - how to workaround?
by Mike Lykov 19 Nov '18

19 Nov '18

Hi all. I'm testing oVirt (it's new to me also) and create some VM with nearly-all-default parameters. (ovirt 4.2.7, with last updates) I create one disk for VM (via webui) : General -> create -> new image with default interface virtio-scsi (boot, 50 Gb size) resource allocation - virtio-scsi enabled by default IO threads enabled by default I run it with cdrom+iso for install centos. When i try to reboot it this VM can start or not can start with error (one time start, next reboot - not start, sometimes after it start...) [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (ForkJoinPool-1-worker-3) [] EVENT_ID: VM_DOWN_ERROR(119), VM test_rh1 is down with error. Exit message: Ошибка XML: Обнаружено нескол ько контроллеров «scsi» с индексом «0». (by the way , why errors are localised? it means "Multiple 'scsi' controllers with index '0'" In engine log here is a config xml dump: <controller type="scsi" index="0"> <address bus="0x00" domain="0x0000" function="0x0" slot="0x05" type="pci"/> </controller> <controller type="scsi" model="virtio-scsi" index="0"> <driver iothread="1"/> <alias name="ua-8d89c0be-523d-4e8f-8968-3658adcd6748"/> </controller> It is really contain two controllers: <controller type="scsi" index="0"> <controller type="scsi" model="virtio-scsi" index="0"> But I do NOT add two this controllers by hand! And sometimes it can start! (without configuration change) So there is a Question: How to workaround this and start the VM? In "vm devices" I have two controllers: virtio-scsi {ioThreadId=1} scsi {type=pci, slot=0x05, bus=0x00, domain=0x0000, function=0x0 {index=0} But all checkboxes are greyed bug like in this list post: https://lists.ovirt.org/pipermail/users/2018-February/086860.html There is a "CLOSED" bugs about this https://bugzilla.redhat.com/show_bug.cgi?id=1543833#c9 https://bugzilla.redhat.com/show_bug.cgi?id=1563769 https://bugzilla.redhat.com/show_bug.cgi?id=1535961 -- Mike

GlusterFS LibgfApiSupported and High Availability
by Shawn Weeks 19 Nov '18

Currently when LibgfApiSupported is enabled it looks like the startup command for the VM has the Gluster hostname always set to the same host. How does that work if that host is down? In my case GlusterFS has 3x replication and distribution enabled but if the first host is down the VMs don't work. I'm on GlusterFS 4.1 and oVirt 4.2 latest. Thanks Shawn

Can't install windows guest
by bardos.matyas＠techcentral.hu 18 Nov '18

18 Nov '18

Dear list, I am new in ovirt, and I have a problem, which I can’t solve with google. I am not able to install windows guests, because they can’t find they disk. I have already many linux guests running, so generally everything is working fine. I try with virtio-scsi disks. What I already tried: - While the installation process I changed the disk to the virtio driver disk (downloaded from fedora project), I try to load scsi drivers, and windows still can’t find the disk - I tried with virtio floppy (run once) but the floppy is not visible in windows select menu - I added the drivers to windows installer wim, but disks still not visible - I tried to add ide drive, but it is not visible either (I have disabled virtio scsi under resource allocation too, without luck) - tried windows 7 and 2016 My nodes are: oVirt Node 4.2.1.1 I use local disks but via nfs, so i share the local disk via nfs. Do you have any idea what could I try. Any clue are welcome, because I’m stuck… Thank you in advance! Regards!

Unable to import engine
by Alex K 18 Nov '18

18 Nov '18

Hi all, I had a setup with ovirt 4.2.0 which at some point the engine stopped responding, due to some split brain issues. Since was not able to resolve the split brain, I proceeded to redeploy the engine. The steps I followed: 1. upgrade servers (yum update) 2. ran ovirt-hosted-engine-cleanup 3. deployed engine (now 4.2.7) The deploy was successful and was able to add a new data domain. The issue is that at this point I would expect the engine storage domain and VM to be automatically imported, but it is not.

Script for backing up VMs
by mail＠karloluiten.nl 18 Nov '18

18 Nov '18

Hi All, I love oVirt, have been running it for some weeks now. I have read the wiki page on backups, and have set up an engine backup. The backing up of VMs is where it gets more tricky. There must be more people already doing this, but I just would like some script that takes my vm name as an argument, and saves a backup (snapshot) of the vm. If someone could help me, that would be awesome. If there is an even easier way to do it (copying files on the FS itself?), that could be even better. I know this question has been asked multiple times over the last years, but I can not find an actual, working, documented way of doing this. Thanks so much, and thanks for creating/maintaining/fixing/building oVirt! Karlo

Increasing an Existing iSCSI Storage Domain
by Brian Wilson 17 Nov '18

17 Nov '18

My Question is not so much in how to do this as i have been able to take an existing Storage domain and increase its size with adding another LUN. My Question is how will a failure of one of the LUNs be handled by the engine and how will it effect the VMs running on it. Let me setup an example to better illustrate. Ovirt Node has ISCSI storage domain comprised of 1 Lun from 1 ISCSI based SAN and 2 LUNs from another. So a total of 3 Luns making up the one storage domain. Now there is an issue with the Storage array providing the single lun. What happens? How do you know what VMs are running on each extent? TIA Brian

Hyperconverged Ovirt + ZFS
by Thomas Simmons 17 Nov '18

17 Nov '18

Hello All, I recently took a new job in a RedHat shop and I'd like to move all of my homelab systems to RedHat upstream products to better align with what I manage at work. I had a "custom" (aka - hacked together) 3-node Hyperconverged XenServer cluster and would like to get this moved over to Ovirt (I'm currently testing with 4.2.7). Unfortunately, my storage is limited to software RAID with a 128GB SSD for cache. If at all possible, I would prefer to use ZFS (RAIDZ+ZIL+L2ARC) instead of MD RAID + lvmcache, however I'm not able to get this working and I'm not sure why. My ZFS and Gluster configuration is working - at least where I can manually mount all of my gluster volumes from all of my nodes, however, hosted-engine --deploy fails. I understand this isn't an out of the box configuration for Ovirt, however I see no reason why this shouldn't work. I would think this would be no different than using any other Gluster volume for the engine datastore, Am I missing something that would prevent this from working? [ INFO ] TASK [Add glusterfs storage domain] [ ERROR ] Error: Fault reason is "Operation Failed". Fault detail is "[Storage Domain target is unsupported]". HTTP response code is 400. [ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "deprecations": [{"msg": "The 'ovirt_storage_domains' module is being renamed 'ovirt_storage_domain'", "version": 2.8}], "msg": "Fault reason is \"Operation Failed\".

Engine ISO Uploader - SSL Peer Not Trusted
by Shawn Weeks 17 Nov '18

17 Nov '18

Trying to upload an iso using engine-iso-uploader on a hosted-engine instance and I'm getting an SSL Error. I followed the directions at https://www.ovirt.org/documentation/admin-guide/appe-oVirt_and_SSL/ to setup SSL and am able to login to the Admin console without an issue. Also checked that things like curl recognize the CA correctly. Not sure where engine-iso-uploader is getting it's trust store. [root@cloud ~]# engine-iso-uploader list Please provide the REST API password for the admin@internal oVirt Engine user (CTRL+D to abort): ERROR: Unable to connect to REST API at https://cloud.dev.example.com:443/ovirt-engine/api due to SDK error Message: Error while sending HTTP request: (60, "Peer's certificate issuer has been marked as not trusted by the user.") What am I missing? Thanks Shawn

how to allow VM to query external DHCP server
by Jarosław Prokopowski 16 Nov '18

Hi, It seems my VMs are not able to send DHCP requests to external DHCP server located in the same network as oVirt hosts. Can anyone tell me how I can enable this? Thanks Jarek
