how to edit a floating disk
by Gianluca Cecchi 22 Nov '18

22 Nov '18

Hello, sometimes I need to modify a not assigned disk, eg change description, change alias or extend in size. Nowadays I do it through temporary assignment to a VM from where I can "edit" the disk. Instead in Storage --> Disks or Storage --> Domains --> Domain Name --> Disks I cannot do it Is it intended by design? Do you think it could be useful to be able to edit in some way also in these two modes and not only when attached to a VM? Gianluca

How to change the master storage domain to another specific domain
by Ladislav Humenik 22 Nov '18

22 Nov '18

Hello, is there any plan to add the possibility (or working way) to change the storage master domain to a specific, let's say by admin chosen storage domain, without shutting down all guests and moving all other domains in to maintenance as described in this old solution: https://access.redhat.com/solutions/34923 Any API call or whatever will be welcome. -- Ladislav Humenik

OVF update failure? Export domain.
by Jacob Green 21 Nov '18

21 Nov '18

So, I found this bug report Bug 1554116 <https://bugzilla.redhat.com/show_bug.cgi?id=1554116#c1>, and it looks like it was squashed(fixed) in ovirt 4.2.2. I am running 4.2.6 and yesterday when I was placing our export domain in maintenance and detaching, I saw this message about ignoring OVF update failure. I was able to Detach and Reattach the export Domain without any problems. But I wanted to know if this is normal or not? I did not check the box on either occasion. Thank you -- Jacob Green Systems Admin American Alloy Steel 713-300-5690

About Windows guest agent
by jingjie.jiang＠oracle.com 20 Nov '18

20 Nov '18

Hi, I am new in oVirt and I'd like to get the clarification about the packages which support the function of Window guest agent from 4.2 release and how to build it. I looked through the document from ovirt.org, such as https://www.ovirt.org/documentation/internal/guest-agent/guest-agent-for-wi… It mentioned: "With the release of oVirt 3.5 we have introduced the oVirt WGT (Windows Guest Tools). The oVirt WGT provides an ISO with all the tools and drivers one needs to install on a Windows VM, with an easy to use installer to install it all in one step. So manual compilation and installation of oVirt Guest Agent is no longer necessary. The oVirt WGT ISO is included in ovirt-guest-tools-iso-3.5-7.noarch.rpm package." Now, ovirt-guest-tools-iso is up to 4.2.4. I found the src rpm from https://resources.ovirt.org/pub/ovirt-4.2/rpm/el7/SRPMS/ovirt-guest-tools-i…, but I could not find ovirt-guest-tools-iso from github, only found ovirt-wgt. After clone the ovirt-wgt, I got the SPICE-tools-0.141.iso built. My question is : 1. Is ovirt-wgt used for Windows guest? 2. If so, how can I build ovirt-guest-tools-iso package or ovirt-tools-setup.iso Thanks, Jingjie

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

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.

Hi all. I'm testing oVirt (it's new to me also) and create some VM with nearly-all-default parameters.

(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

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
