Unassigned hosts

Hi oVirt land Hope you are well. Got a bit of an issue, actually a big issue. We had some sort of dip of some sort. All the VM's is still running, but some of the hosts is show "Unassigned" or "NonResponsive". So all the hosts was showing UP and was fine before our dip. So I did increase vdsHeartbeatInSecond to 240, no luck. I still get a timeout on the engine lock even thou I can connect to that host from the engine using nc to test to port 54321. I also did restart vdsmd and also rebooted the host with no luck. nc -v someserver 54321 Ncat: Version 7.50 ( https://nmap.org/ncat ) Ncat: Connected to 172.40.2.172:54321. 2020-08-05 20:20:34,256+02 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (EE-ManagedThreadFactory-engineScheduled-Thread-70) [] EVENT_ID: VDS_BROKER_COMMAND_FAILURE(10,802), VDSM someserver command Get Host Capabilities failed: Message timeout which can be caused by communication issues Any troubleshoot ideas will be gladly appreciated.

What would have helped me is a diff of what was removed. Ultimately, I didn't have enough time to dig for the diff, but if you know where it can be found it may be of use for other people that need to use a Penryn based server. Hi, the diff is right there, the option value for 4.2 cluster still has it. so you just need that piece (penryn definition) to copy&paste into the 4.4 entry(i think the numbers are then duplicated, but it shouldn’t really matter, cpu name is the "key”) Thanks, michal > > I was able to swap two systems at my place and get a Nehalem one to use with oVirt, but if I get a chance I may try to revert to the older one since it's a bit more convenient for me to use.

Setting Up oVirt + NFS Storage Issues
by Arden Shackelford 07 Aug '20

07 Aug '20

Hello! Been looking to get setup with oVirt for a few weeks and had a chance the past week or so to attempt getting it all setup. Ended up doing a bit of troubleshooting but finally got to the point where the Cockpit setup prompts for me setting up the storage piece, for which I've opted for NFS (path of least resistance for now). However, I constantly run into this issue (pulled from the administration portal events page): VDSM asgard.shackfam.net command CreateStorageDomainVDS failed: Could not initialize cluster lock: () This specifically shows up in the following task for the Ansible piece: [ovirt.hosted_engine_setup : Add NFS storage domain] When I browse the NFS share, I do see a file structure being created, which kind of confuses me based on the error provide in the Administration portal. Any suggestions on what would be best steps forward at this point? For reference, here's my setup: 1x oVirt Node 1x NFS server (storage01: NFS shares mainly managed by ZFS)

4.2.8 and yum update
by carl langlois 06 Aug '20

06 Aug '20

Hi all, I am in the process of upgrading our cluster to 4.3. But first i need to update everything to 4.2.8 and update the os to the latest 7.x. I was able to update the self-hosted engine to the latest 4.2.8 and centos 7.8. But when i tried to update the host yum update got broken gluster packages. The current host that i'm trying to update is on 7.5. If i look at the release note i can see that ovirt 4.2.8 needs 7.6. Not sure how to resolve this. Any suggestions?. Carl

useful workaround for catch-22 situation with nic drivers and Windows
by i iordanov 06 Aug '20

06 Aug '20

Hello, I just wanted to post a nice workaround I came up with in case it helps anybody. The reason I needed it is that in oVirt 4.4, it appears I am unable to change the nic1 type when creating VMs (maybe that's a bug?) and I necessarily end up with the default nic1 type which needs a virtio driver in Windows which is obviously not present on a clean install. Also, since there is no networking, it can't be downloaded. I did think of mounting a USB stick via remote-viewer, but something is wonky there too - the USB device selection menu item is grayed out, and no, it's not permissions. So what i did was to create an .iso file with spice-guest-tools-latest.exe in it and copy the resulting iso file to the ISO domain. Then, I was easily able to attach the ISO to the Windows machine in question and install spice-guest-tools, which made the network adapter work. Quick snippet of how I created the .iso: $ find test test test/spice-guest-tools-latest.exe $ mkisofs -o spice-tools.iso test I: -input-charset not specified, using utf-8 (detected in locale settings) Total translation table size: 0 Total rockridge attributes bytes: 0 Total directory bytes: 116 Path table size(bytes): 10 Max brk space used 0 5124 extents written (10 MB) Hope it helps somebody :). Cheers! iordan -- The conscious mind has only one thread of execution.

Resize partition cause oVirt installation failed
by hkexdong＠yahoo.com.hk 06 Aug '20

I've 2 x 512GB SSD. Purely for oVirt 4.4.1 (CentOS 8.2) installation. Using auto partitioning will assign 800+ GB to root partition. I think that's too much so manually reduce it to 80 GB. As there are 2 disks. I want to form RAID too. So, I manually change all the partitions from "LVM thin provisioning" to "RAID" (with RAID 1). Eventually, cause the installation failed with a message "There was an error running the kickstart script at line ....." If I don't make any change to the partitions. The installation success. Is this a known issue? oVirt not allow resize partition and using Linux software RAID?

General Design question for oVirt set up between locations
by Holger Petrick 05 Aug '20

05 Aug '20

Hello, I'm looking to deploy oVirt for a company which has locations in different countries. As I know and also set up in my test environment, the oVirt Engine is the central place to manage different Data Center in a central place. But how to manage a location when the network connection between a Data Center and oVirt Engine is down? Is it possible to set up on each location a hosted engine and connect also the "local" engine / hosts to a "Central" Engine? What is the recommendation to deploy oVirt on multiple location? Thank you. Holger
