Failure Of Latest oVirt Installation - Missing Packages
by Matthew J Black 13 Sep '22

13 Sep '22

Hi All, This is all on a Rocky Linux 8.6 box, as a CLI oVirt self-hosted engine install. I have followed all of the instructions (include the special RHEL and derivatives and Rocky Linux instructions) in the oVirt documentation. So, I'm attempting to install the ovirt-hosted-engine-setup rpm (ie dnf -y install ovirt-hosted-engine-setup), and I'm getting failures involving the following packages (ie the following packages cannot be found): - collectd >= 5.12.0-7 - collectd-disk >= 5.12.0-7 - collectd-write_http >= 5.12.0-7 - collectd-write_syslog >= 5.12.0-7 - collectd-netlink >= 5.12.0-7 - collectd-virt >= 5.12.0-7 - python3-os-brick The full dnf error message is: ~~~ Error: Problem: package ovirt-hosted-engine-setup-2.6.5-1.el8.noarch requires ovirt-host >= 4.5.0, but none of the providers can be installed - package ovirt-host-4.5.0-3.el8.x86_64 requires ovirt-host-dependencies = 4.5.0-3.el8, but none of the providers can be installed - cannot install the best candidate for the job - nothing provides collectd >= 5.12.0-7 needed by ovirt-host-dependencies-4.5.0-3.el8.x86_64 - nothing provides collectd-disk >= 5.12.0-7 needed by ovirt-host-dependencies-4.5.0-3.el8.x86_64 - nothing provides collectd-write_http >= 5.12.0-7 needed by ovirt-host-dependencies-4.5.0-3.el8.x86_64 - nothing provides collectd-write_syslog >= 5.12.0-7 needed by ovirt-host-dependencies-4.5.0-3.el8.x86_64 - nothing provides collectd-netlink >= 5.12.0-7 needed by ovirt-host-dependencies-4.5.0-3.el8.x86_64 - nothing provides collectd-virt >= 5.12.0-7 needed by ovirt-host-dependencies-4.5.0-3.el8.x86_64 - nothing provides python3-os-brick needed by ovirt-host-dependencies-4.5.0-3.el8.x86_64 ~~~ Doing a dnf with --nobest produces similar results ie: ~~~ Error: Problem: conflicting requests - package ovirt-hosted-engine-setup-2.6.3-1.el8.noarch requires ovirt-host >= 4.5.0, but none of the providers can be installed - package ovirt-hosted-engine-setup-2.6.4-1.el8.noarch requires ovirt-host >= 4.5.0, but none of the providers can be installed - package ovirt-hosted-engine-setup-2.6.5-1.el8.noarch requires ovirt-host >= 4.5.0, but none of the providers can be installed etc ~~~ In all of the repos (& mirrors) I've looked at the latest version of collectd* (for EL8) is 5.9.0-5, and I can't locate python3-os-block at all. pkgs.org says that even the version of collectd* in the Centos 8 Repos is v5.9.0-5 in the EPEL EL8 repo. According to rpmfind.net there is a 5.12.0-23 version of collectd* in the EPEL EL9 repo, but I read somewhere that oVirt is not-production-ready on EL9, so I don't have the EPEL EL9 repo "available". pkgs.org says that the only versions it knows about for pyton3-os-brick are for Debian and Ubuntu, and rpmfind.net doesn't list it at all (which makes sense if there are only versions from Debia-based distros). Could someone please point me towards an EL8 repo where I can get the required packages, or, if I'm being totally stupid, what I'm doing wrong? Thanks in advance Dulux-Oz

Slow upload via oVirt Manager
by markeczzz＠gmail.com 13 Sep '22

13 Sep '22

Hi! I am trying to upload some rather large disk images via oVirt Web Manager, but I am getting rather slow speeds. Network is 1Gbps between my pc and oVirt node via which I am uploading, but I am getting around 200Mbps transfer speed. Last time when I was uploading was when I had version 4.4 of oVirt and I haven't had that problem then. Now I am using latest version. Any steps how to troubleshoot this?

vdsm.log full of "error" because node don't run the "engine"
by Diego Ercolani 12 Sep '22

12 Sep '22

Hello, I don't know if it's normal but in all the nodes of the cluster (except the one that runs the engine) I have something like: 2022-09-12 15:41:54,563+0000 INFO (jsonrpc/0) [api.virt] START getStats() from=::1,57578, vmId=8486ed73-df34-4c58-bfdc-7025dec63b7f (api:48) 2022-09-12 15:41:54,563+0000 INFO (jsonrpc/0) [api] FINISH getStats error=Virtual machine does not exist: {'vmId': '8486ed73-df34-4c58-bfdc-7025dec63b7f'} (api:129) 2022-09-12 15:41:54,563+0000 INFO (jsonrpc/0) [api.virt] FINISH getStats return={'status': {'code': 1, 'message': "Virtual machine does not exist: {'vmId': '8486ed73-df34-4c58-bfdc-7025dec63b7f'}"}} from=::1,57578, vmId=8486ed73-df34-4c58-bfdc-7025dec63b7f (api:54) 2022-09-12 15:41:54,563+0000 INFO (jsonrpc/0) [jsonrpc.JsonRpcServer] RPC call VM.getStats failed (error 1) in 0.00 seconds (__init__:312) The UUID 8486ed73-df34-4c58-bfdc-7025dec63b7f is the UUID of the Hosted-engine VM, obviously it run only in one noe and, as I undestand, the other nodes are querying the VM state only to fence the VMs if is started on more node at a time... but having the log full of these "error" are annoying. I would prefer to have the word "error" only in meaningful context. This if the hypotesis of my interpretation is correct, if it's a true error, then please address me how to fix it. Thank you.

remote-viewer "Change CD menu" contains ISOs only from one storage domain
by Alexander Murashkin 09 Sep '22

09 Sep '22

remote-viewer "Change CD menu" contains ISOs only from one storage domain. There are two "data" storage domains in the datacenter. Both of them contains ISOs and VM disk images. The first VM has a disk image in the first storage domain and so is shown in the domain's "Virtual Machine" tab. Similar, the second VM has a disk image in the second storage domain and so is also shown in the domain's "Virtual Machine" tab. When the VMs are running, in their consoles, in "Change CD menu" only ISOs from the first storage domain are listed. I would consider it a bug. It is possible to attach ISO from any storage domain to any VM. But it is not possible to see ISO from the second domain in "Change CD menu". Engine RPM: ovirt-engine-4.5.2.5-1.el8.noarch. Desktop RPMs: libgovirt-0.3.8-3.fc36.x86_64 virt-viewer-11.0-2.fc36.x86_64 Shall I open a bug in Bugzilla? If so, what component it is related to - libgovirt? Alexander Murashkin PS I also have tried ISO domain. No luck.

VM remote console issue related to VNC and Root CA certs?
by Chris Smith 08 Sep '22

08 Sep '22

Hello, I have built a small 2 cluster "datacenter". One host is oVirt 4.5.1 and another 4.5.2. Each host is in it's own cluster due to CPU type difference. I am able to build VMs on each host and they are able to start. My issue I am fighting now is that I am unable to get remote-viewer.exe to open a remote console window to a VM on the 2nd cluster I've built. I'm trying to connect to a VM named "utm" which is running on host "mini-node" which is in a separate cluster from where "ovirt-node" resides. "ovirt-node" is the host where "ovirt-engine" resides. I have attached the whole log to this e-mail from my windows machine, and I think this part is most relevant: [image: image.png] I've tried to install the SSL certs for each server (from tcp/9090) on my windows workstation's cert store in both user and computer personal and trusted root ca store, but i'm not sure that the cert I have for my 2nd host is made right? [image: image.png] [image: image.png] This is my ovirt engine cert (ignore the comcast.net domain name, that is due to linksys nonsense that i'm just running with): [image: image.png] [image: image.png] I wonder, should SSL cert for "mini-node" have been issued by "ovirt-engine"? i think it's self-signed at the moment. Here is what my console.vv looks like: [virt-viewer] type=vnc host=mini-node.hsd1.fl.comcast.net port=5900 password=<snip> # Password is valid for 120 seconds. delete-this-file=1 fullscreen=0 title=utm:%d toggle-fullscreen=shift+f11 release-cursor=shift+f12 secure-attention=ctrl+alt+end versions=rhev-win64:2.0-160;rhev-win32:2.0-160;rhel8:7.0-3;rhel7:2.0-6;rhel6:99.0-1 newer-version-url= http://www.ovirt.org/documentation/admin-guide/virt/console-client-resources [ovirt] host=ovirt-engine.hsd1.fl.comcast.net:443 vm-guid=cdfe33fc-4d6e-425d-b5d2-d999f56ea4ea sso-token=<snip> admin=1 ca=-----BEGIN CERTIFICATE----- <snip> Any help is appreciated, Thank you, Chris

Cannot upgrade hosted-engine due to a LUN in a storage domain
by virden-gerald＠aramark.com 08 Sep '22

08 Sep '22

I need to know if there are any cli commands to manage storage domains. I have a completely empty LUN in a storage domain but I can't use it to apply to my hosted-engine upgrade. I think I need to put the storage domain into maintenance mode and remove it but I don't have the GUI to do this. Anyone know how to use the command line for this?
