Libgfapi considerations
by Jayme 01 Jul '21

01 Jul '21

Are there currently any known issues with using libgfapi in the latest stable version of ovirt in hci deployments? I have recently enabled it and have noticed a significant (over 4x) increase in io performance on my vms. I’m concerned however since it does not seem to be an ovirt default setting. Is libgfapi considered safe and stable to use in ovirt 4.3 hci?

Grafana oVirt 4.4.4 Node install - Grafana Monitoring Portal not available
by simon＠justconnect.ie 22 Jun '21

22 Jun '21

Having installed oVirt 4.4.4 HCI 3 node cluster, the Grafana 'Monitoring Portal' was not visible on the Default page. It appears that Grafana is installed but not configured. I have checked a 4.4.3 environment and it is installed and running, so is this a bug with 4.4.4.7-1.el8? Any help would be appreciated.

supervdsm failing during network_caps
by Alan G 24 Mar '21

24 Mar '21

Hi, I have issues with one host where supervdsm is failing in network_caps. I see the following trace in the log. MainProcess|jsonrpc/1::ERROR::2020-01-06 03:01:05,558::supervdsm_server::100::SuperVdsm.ServerCallback::(wrapper) Error in network_caps Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/supervdsm_server.py", line 98, in wrapper res = func(*args, **kwargs) File "/usr/lib/python2.7/site-packages/vdsm/network/api.py", line 56, in network_caps return netswitch.configurator.netcaps(compatibility=30600) File "/usr/lib/python2.7/site-packages/vdsm/network/netswitch/configurator.py", line 317, in netcaps net_caps = netinfo(compatibility=compatibility) File "/usr/lib/python2.7/site-packages/vdsm/network/netswitch/configurator.py", line 325, in netinfo _netinfo = netinfo_get(vdsmnets, compatibility) File "/usr/lib/python2.7/site-packages/vdsm/network/netinfo/cache.py", line 150, in get return _stringify_mtus(_get(vdsmnets)) File "/usr/lib/python2.7/site-packages/vdsm/network/netinfo/cache.py", line 59, in _get ipaddrs = getIpAddrs() File "/usr/lib/python2.7/site-packages/vdsm/network/netinfo/addresses.py", line 72, in getIpAddrs for addr in nl_addr.iter_addrs(): File "/usr/lib/python2.7/site-packages/vdsm/network/netlink/addr.py", line 33, in iter_addrs with _nl_addr_cache(sock) as addr_cache: File "/usr/lib64/python2.7/contextlib.py", line 17, in __enter__ return self.gen.next() File "/usr/lib/python2.7/site-packages/vdsm/network/netlink/__init__.py", line 92, in _cache_manager cache = cache_allocator(sock) File "/usr/lib/python2.7/site-packages/vdsm/network/netlink/libnl.py", line 469, in rtnl_addr_alloc_cache raise IOError(-err, nl_geterror(err)) IOError: [Errno 16] Message sequence number mismatch A restart of supervdsm will resolve the issue for a period, maybe 24 hours, then it will occur again. So I'm thinking it's resource exhaustion or a leak of some kind? Running 4.2.8.2 with VDSM at 4.20.46. I've had a look through the bugzilla and can't find an exact match, closest was this one https://bugzilla.redhat.com/show_bug.cgi?id=1666123 which seems to be a RHV only fix. Thanks, Alan

OVirt rest api 4.3. How do you get the job id started by the async parameter
by pascal＠butterflyit.com 10 Feb '21

10 Feb '21

I am using the rest api to create a VM, because the VM is cloned from the template and it takes a long time, I am also passing the async parameters hoping to receive back a job id, which I could then query https://xxxxx/ovirt-engine/api/vms?async=true&clone=true however I get the new VM record which is fine but then I have no way of knowing the job id I should query to know when it is finished. And looking at all jobs there is no reference back to the VM execept for the description <job href="/ovirt-engine/api/jobs/d17125c7-6668-4b6c-ad22-95121cb66a31" id="d17125c7-6668-4b6c-ad22-95121cb66a31"> <actions> <link href="/ovirt-engine/api/jobs/d17125c7-6668-4b6c-ad22-95121cb66a31/clear" rel="clear"/> <link href="/ovirt-engine/api/jobs/d17125c7-6668-4b6c-ad22-95121cb66a31/end" rel="end"/> </actions> <description>Creating VM DEMO-PCC-4 from Template MASTER-W10-20H2-CDrive in Cluster d1-c2</description> <link href="/ovirt-engine/api/jobs/d17125c7-6668-4b6c-ad22-95121cb66a31/steps" rel="steps"/> <auto_cleared>true</auto_cleared> <external>false</external> <last_updated>2021-01-21T12:49:06.700-08:00</last_updated> <start_time>2021-01-21T12:48:59.453-08:00</start_time> <status>started</status> <owner href="/ovirt-engine/api/users/0f2291fa-872a-11e9-b13c-00163e449339" id="0f2291fa-872a-11e9-b13c-00163e449339"/> </job>

The he_fqdn proposed for the engine VM resolves on this host - error?
by lejeczek 07 Feb '21

07 Feb '21

hi chaps, a newcomer here. I use cockpit to deploy hosted engine and I get this error/warning message: "The he_fqdn proposed for the engine VM resolves on this host" I should mention that if I remove the IP to which FQDN resolves off that iface(plain eth no vlans) then I get this: [ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "The selected network interface is not valid"} All these errors seem bit too cryptic to me. Could you shed bit light on what is oVirt saying exactly and why it's not happy that way? many thanks, L.

Upgrade from 4.4.3 to 4.4.4 (oVirt Node) - vdsmd.service/start failed with result 'dependency'
by Marco Fais 04 Feb '21

04 Feb '21

Hi all, I have just upgraded one of my oVirt nodes from 4.4.3 to 4.4.4. After the reboot, the 4.4.4 image is correctly loaded but vdsmd is not starting due to this error: vdsmd.service: Job vdsmd.service/start failed with result 'dependency'. Looks like it has a dependency on mom-vdsm, and this as well has a dependency issue: mom-vdsm.service: Job mom-vdsm.service/start failed with result 'dependency'. After some investigation looks like mom-vdsm has a dependency on ovsdb-server, and this is the unit creating the problem: ovs-delete-transient-ports.service: Starting requested but asserts failed. Assertion failed for Open vSwitch Delete Transient Ports Failed to start Open vSwitch Database Unit. Details below: -- Unit ovsdb-server.service has begun starting up.

Storage domain problems. oVirt 4.4.4.
by Yury Valitsky 02 Feb '21

02 Feb '21

Hi, all. I deployed a new oVirt 4.4.4 installation and imported FC storage domains. However, two storage domains turned out to be empty - they did not have virtual machines in the "VM import" tab, the virtual disks appeared in the "disk import" tab with empty aliases. I downloaded and viewed the OVF_STORE - the old information was partially overwritten by the new one with an empty number of VMs. Trying to restore the VM configuration information, I deployed a backup of the old hosted engine. Version is also 4.4.4. Thus, it was possible to restore OVF_STORE of the first problematic disk domain. But the second storage domain gave an error when updating OVF_STORE. The same error occurs when trying to export a VM or copy a virtual disk to another known good storage domain. At the same time, I successfully download disks from the second storage domain to my PC by clicking the Download button and saving *.raw. But snapshots cannot be saved like this. 1. How can I overwrite OVF_STORE on the second storage domain? If for this I need to restore the oVirt metadata on the storage domain, how can I do it correctly? 2. How can I download VM configuration that has been saved in the hosted engine? Thanks in advance for your help. WBR, Yury Valitsky

Users cannot create disks in portal
by jwmccullen＠pima.edu 02 Feb '21

02 Feb '21

Help, banging my head against a wall. Ovirt Engine Software Version:4.4.4.7-1.el8 RHEL 8.3 I have set up my cluster going to a TrueNAS storage. Everything is going great and works well from Admin or any user with SuperUser. I would like to set it up so that students can create their own machines. Great, plowing through the documentation it looks like after creating a user, it works well by giving them at the Data Center object the user roles of: PowerUserRole VmCreator At that level, according to my reading of the documentation, it is also supposed to grant DiskCreator automatically. Well, when I do that it creates the VM but the creation of the disk does not work. Looking in the log I find: Validation of action 'AddImageFromScratch' failed for user will@internal-authz. Reasons: VAR__TYPE__STORAGE__DOMAIN,NON_ADMIN_USER_NOT_AUTHORIZED_TO_PERFORM_ACTION_ON_HE Could anyone please let me know what this is referring to? I have tried many roll combinations, and have even made my own user roll with full privileges to no avail. I looked for issues and the closest I could find is: Bug 1511697 - [RFE] Unable to set permission on all but Hosted-Engine VM and Storage Domain Which showed as resolved in 4.3 Could someone be kind enough to maybe tell me where I am missing it?

Hello.which environment type I choose?
by 欧文 02 Feb '21

02 Feb '21

Dear: Hello. My name is Owen. First, I appreciate you spend time to check my email. Recently I want to use oVirt to build a project. But after reading the official document, I have some questions to ask. The project is intended to set up a physical server that is used to implement virtualization, Variable quantity of thin clients for users. But I don't know which environment types I should use to deploy. The number two question is why the system environment is different between each version of o-virt？Because centos 7 is the major version. But so many versions of o-virt is not centos 7 or centos 8.can you tell me the reason. Thank you.At last, I have a question.I ever joined the IRC, but there is no response to answer my question. Could you tell me where I can take part in the community with developers who develope o-virt.Thanks

move ovirt 4.3.9 to RHEL 8
by Paul Dyer 01 Feb '21

01 Feb '21

Hi, I am laying the groupwork for upgrade ovirt to 4.4. Since the standalone ovirt mgr is now running on RHEL 7, I have installed RHEL 8 to a new VM. Unfortunately, after installing ovirt-release43, I am not able to find documentation for the dnf modules required. All the current documentation point to ovirt-release44 and dnf modules not available for ovirt 4.3/RHEL 8. I have these repos enabled... Repo ID: ansible-2-for-rhel-8-x86_64-rpms Repo ID: rhel-8-for-x86_64-appstream-rpms Repo ID: rhel-8-for-x86_64-baseos-rpms I am looking setup docs for a standalone engine of ovirt 4.3 on RHEL 8. Thanks! -- Paul Dyer, Mercury Consulting Group, RHCE 504-338-8750

Custom Fence Agent
by Robert Tongue 01 Feb '21

01 Feb '21

Greetings everyone, I am having another problem that I was hoping to get some assistance with. I have created my own custom fence agent for some tasmota-flashed wifi smart plugs, that can control plug power input to ovirt nodes. This works great; however I am running into a problem getting it added to ovirt as a power manager. I got the custom fence agent added with engine-config -s, and it shows up in the webui to select as a power management agent, then I put in the details for the plug, IP address, login, password, and press the "test" button, which passes, and shows the status as power=on. Once I save the settings, however, it is logged in the engine.log file that fencing will fail, because there is no node available to proxy the operation. When I go back into the power management settings, and press "test" again, then I get the error: "Test failed: Failed to run fence status-check on host 'ovirt1'. No other host was available to serve as proxy for the operation." I have the agent script in /usr/sbin/ on all nodes, execute permissions set, and I can run it manually at the command line just fine, so I am really at a loss here as what to check. What am I missing here? Please help. Thank you for your time. Script: #!/usr/libexec/platform-python -tt from urllib.parse import quote import requests import sys import atexit sys.path.append("/usr/share/fence") from fencing import * def set_power_status(conn, options): if "on" in options["--action"]: response = requests.get(buildUrl(options, "on")) elif "off" in options["--action"]: response = requests.get(buildUrl(options, "off")) return def get_power_status(conn, options): response = requests.get(buildUrl(options, "status")) if "\"Power\":0" in response.text: return "off" elif "\"Power\":1" in response.text: return "on" def buildUrl(options, action): cmnd = { 'on' : 'Power On', 'off' : 'Power Off', 'status' : 'Status' } return "http://" + options["--ip"] + "/cm?user=" + quote(options["--username"]) + "&password=" + quote(options["--password"]) + "&cmnd=" + quote(cmnd.get(action, "Error")) def main(): device_opt = ["ipaddr", "login", "passwd", "web"] atexit.register(atexit_handler) all_opt["power_wait"]["default"] = 5 options = check_input(device_opt, process_input(device_opt)) docs = {} docs["shortdesc"] = "Fence agent for Tasmota-flashed Smarthome Plugs" docs["longdesc"] = "" docs["vendorurl"] = "" show_docs(options, docs) ## ## Fence operations #### result = fence_action(None, options, set_power_status, get_power_status) sys.exit(result) if __name__ == "__main__": main()

AFFINITY GROUPS
by LS CHENG 31 Jan '21

31 Jan '21

Hi I would like to know how AFFINITY GROUPS works. I have 2 VM in 2 hosts, each VM runs in a host. Let's call HOST_X where vm01 runs HOST_Y where vm02 runs I have set up an affinity group where it says vm01 relates to HOST_X, vm02 relates to HOST_Y. VM affinity rule is set to negative and HOST affinity rule set to positive. I need both vm01 and vm02 to run in their respective physical host. I have a problem, when vm01 is stopped and HOST_Y is rebooted vm02 starts in HOST_X, how can I avoid that? Thank you Luis Sanchez

recovering gluster volumes when moving hosts to a new datacenter
by Nathanaël Blanchet 30 Jan '21

30 Jan '21

Hi, I moved 3 hosts (for replica 3 volume) from a previous datacenter to a new datacenter. Those hosts had initially been configured in a gluster cluster and managed multiple gluster volume created with ovirt UI. These hosts are now apart of a new gluster cluster and they see each others with cli "gluster peer status" as well as the associated volumes "gluter volumes list". But I can't make gluster volumes visible in the usually "volume" tab, so ovirt doesn't seem to see them. Is there a way to import pre existing gluster volume so as to ovirt be able to manage them ? Thanks. -- Nathanaël Blanchet Supervision réseau SIRE 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanchet(a)abes.fr

Windows 10 on older CPUs
by Chris Adams 29 Jan '21

29 Jan '21

I have an oVirt cluster running 4.3.10 on older hardware with a cluster CPU type of Intel Nehalem. I needed to install a Windows 10 (latest release) VM, which oVirt rejected because of the CPU model. I remember there being issues with certain versions of Windows and this CPU model under oVirt (I don't do Windows very often and had forgotten). I instead told oVirt I was installing Windows 8 (which it accepted), and then installed - it installed and appears to be working just fine. I don't know if Microsoft changed whatever used to break or what... I remember the problem before not even getting through install, so it seems to be okay. Any issues I should be worried about? -- Chris Adams <cma(a)cmadams.net>

ovirt node ng 4.4 crash in anaconda when setting ntp
by Gianluca Cecchi 29 Jan '21

29 Jan '21

Hello, when installing ovirt node ng 4.4 on a Dell M620 I remember I had a crash in anaconda if I try to set up ntp. Using ovirt-node-ng-installer-4.4.4-2020122111.el8.iso As soon as I select it and try to type the hostname to use, all stops and then anaconda aborts. Just today I had the same with the latest RHVH 4.4 iso: RHVH-4.4-20201210.0-RHVH-x86_64-dvd1.iso on an R630. Quite disappointing because I also have to fight with iDRAC8 to install the OS: it is slow to die. In practice I waste about one hour.... Is anyone aware of it or able to reproduce on another platform so that eventually I'm going to open a bug/case for it? My config is default one in anaconda accepting default and creating a bonded connection (LACP). Then as the last step I go into the set time/date and click on the ntp button and I get the problem as soon as I try to type inside the text box. Thanks, Gianluca

[ANN] oVirt 4.4.5 Third Release Candidate is now available for testing
by Sandro Bonazzola 29 Jan '21

29 Jan '21

oVirt 4.4.5 Third Release Candidate is now available for testing The oVirt Project is pleased to announce the availability of oVirt 4.4.5 Third Release Candidate for testing, as of January 29th, 2021. This update is the fifth in a series of stabilization updates to the 4.4 series. How to prevent hosts entering emergency mode after upgrade from oVirt 4.4.1 Note: Upgrading from 4.4.2 GA or later should not require re-doing these steps, if already performed while upgrading from 4.4.1 to 4.4.2 GA. These are only required to be done once. Due to Bug 1837864 <https://bugzilla.redhat.com/show_bug.cgi?id=1837864> - Host enter emergency mode after upgrading to latest build If you have your root file system on a multipath device on your hosts you should be aware that after upgrading from 4.4.1 to 4.4.5 you may get your host entering emergency mode. In order to prevent this be sure to upgrade oVirt Engine first, then on your hosts: 1. Remove the current lvm filter while still on 4.4.1, or in emergency mode (if rebooted). 2. Reboot. 3. Upgrade to 4.4.5 (redeploy in case of already being on 4.4.5). 4. Run vdsm-tool config-lvm-filter to confirm there is a new filter in place. 5. Only if not using oVirt Node: - run "dracut --force --add multipath” to rebuild initramfs with the correct filter configuration 6. Reboot.

How to reset network on all cluster members (controller and host) to defaults for cleans start?
by David Johnson 29 Jan '21

29 Jan '21

I have a new Ovirt 4.4.5 cluster consisting of a controller and a single host, both running on centos 8. I believe I have messed up my network configurations by using a mix of oVirt and nmcli functions to try to resolve problems. Is there an easy way to reset everything on the controller and host machines to get a clean start? Or do I need to start from scratch and re-install centos. Thank you in advance. David Johnson

Gluster volume slower then raid1 zpool speed
by Harry O 28 Jan '21

28 Jan '21

Hi, Can anyone help me with the performance on my 3 node gluster on zfs (it is setup with one arbiter) The performance on the single vm I have on it (with engine) is 50% worse then a single bare metal disk, on the writes. I have enabled "Optimize for virt store" I run 1Gbps 1500MTU network, could this be the write performance killer? Is this to be expected from a 2xHDD zfs raid one on each node, with 3xNode arbiter setup? Maybe I should move to raid 5 or 6? Maybe I should add SSD cache to raid1 zfs zpools? What are your thoughts? What to do for optimize this setup? I would like to run zfs with gluster and I can deal with a little performance loss, but not that much.

vGPU on ovirt 4.3
by kim.kargaard＠noroff.no 28 Jan '21

Hi, We are looking at getting some GPU's for our servers and to use vGPU passthrough so that our students can do some video renders on the VM's. Does anyone have good experience with the Nvidia Quadro RTX6000 or RTX8000 and ovirt 4.3? Thanks. Kim
