Hi Everyone, I am new here and hoping to get some advise on my issue that i'm encountering. I am setting up ovirt self hosting engine 4.5.4 and require proxy to access the internet. Below is the issue i encountered: [localhost -> 192.168.222.66]: FAILED! => {"changed": false, "msg": "Failed to download metadata for repo 'centos-ceph-pacific': Cannot prepare internal mirrorlist: Curl error (6): Couldn't resolve host name for http://mirrorlist.centos.org/?release=8-stream&arch=x86_64&repo=storage-cep… [Could not resolve host: mirrorlist.centos.org]", "rc": 1, "results": []} Hoping to gain some information to solve it. Thank you in advance!

Ovirt 4.4.10 AD Integration Error
by hemak88＠gmail.com 19 Jan '23

19 Jan '23

I am dong AD integration of the Ovirt 4.4 manager. The Insecure method with plain text password saved in /etc/ovirt-engine/aaa/uat.xxxx.com.properties works fine. I am using ovirt-engine-extension-aaa-ldap-setup utility However this is a hard coding method and insecure way. Hence I wanted to use starttls with PEM encoded certificate file. I obtained a root and intermediate CA from the Ad server and used with starttls I used below inputs for configuring AD auth with tool "ovirt-engine-extension-aaa-ldap-setup" Available LDAP implementations: 3 - Active Directory Please select: 3 Please enter Active Directory Forest name: uat.xxxx.com Please select protocol to use (startTLS, ldaps, plain) [startTLS]: startTLS Please select method to obtain PEM encoded CA certificate (File, URL, Inline, System, Insecure): file File path: /tmp/rootca.pem Enter search user DN (for example uid=username,dc=example,dc=com or leave empty for anonymous): myself(a)uat.xxxx.com Enter search user password: Are you going to use Single Sign-On for Virtual Machines (Yes, No) [Yes]: No Please specify profile name that will be visible to users [uat.xxxx.com] Please provide credentials to test login flow: Enter user name: myself(a)uat.xxxx.com Enter user password: But I am facing error. What could be the resolution WARNING: Error while connecting to 'adserver.uat.xxxx.com': LDAPException(resultCode=82 (local error), errorMessage='The connection reader was unable to successfully complete TLS negotiation: SSLHandshakeException(No trusted certificate found), ldapSDKVersion=4.0.14, revision=c0fb784eebf9d36a67c736d0428fb3577f2e25bb') I did verify the root and intemediate certificate: # openssl verify -verbose -CAfile uatrootca.pem uatca.pem uatca.pem: OK 1. What could be the reason for "No trusted certificate found" error? 2. Will this method also save the username and password of AD user as plain text in the file /etc/ovirt-engine/aaa/uat.xxxx.com.properties

oVirt + TrueNAS: Unable to create iSCSI domain - I am missing something obvious
by David Johnson 19 Jan '23

19 Jan '23

Good morning folks, and thank you in advance. I am working on migrating my oVirt backing store from NFS to iSCSI. *oVirt Environment:* oVirt Open Virtualization Manager Software Version:4.4.4.7-1.el8 *TrueNAS environment:* FreeBSD truenas.local 12.2-RELEASE-p11 75566f060d4(HEAD) TRUENAS amd64 The iSCSI share is on a TrueNAS server, exposed to user VDSM and group 36. oVirt sees the targeted share, but is unable to make use of it. The latest issue is "Error while executing action New SAN Storage Domain: Volume Group block size error, please check your Volume Group configuration, Supported block size is 512 bytes." As near as I can tell, oVirt does not support any block size other than 512 bytes, while TrueNAS's smallest OOB block size is 4k. I know that oVirt on TrueNAS is a common configuration, so I expect I am missing something really obvious here, probably a TrueNAS configuration needed to make TrueNAS work with 512 byte blocks. Any advice would be helpful. *David Johnson*

After Upgrade OVirt 4.4.9 > Version 4.4.10.7-1.el8 VM Kernel Crashes after migration
by Ralf Schenk 19 Jan '23

19 Jan '23

Dear List, we upgraded our OVirt 4.4.9 Infrastructure (engine and hosts) to latest available 4.4.10.x. Engine shows "4.4.10.7-1.el8" on Login Page Hosts are based on ovirt-node-ng (nodectl info outputs ovirt-node-ng-4.4.10.2-0.20220303.0) When we migrate VM's we see VM's dying short after migration with below errors also printed to console. We are only able to shutdown these VM's (PowerOff) and start them up again. Mostly they are started again on the Host that was target of migration and they run without issues then. All Servers are EPYC based, but different CPU Versions. All hosts are in a single "Cluster", CPU Type is "Secure AMD EPYC". With 4.4.8 and 4.4.9 we had no problems migrating VM's between hosts. Cluster is: 2 Hosts: AMD EPYC 7401P 24-Core Processor 1 Hosts: AMD EPYC 7402P 24-Core Processor 7 Hosts: AMD EPYC 7502P 32-Core Processor What can we do ? As said, we didn't see such problems for 1 year running 4.4.8.x and 4.4.9.x.

Hello, Yesterday I had to remove the brick of my first server (HCI with 3 servers) for maintenance and recover hard disks. 3 servers with 4 disks per server in raid5. 1 brick per server i did : gluster volume remove-brick data replica 2 ovnode1s.telecom.lan:/gluster_bricks/datassd/datassd force After deleting the brick, I had 8 unsynced entries present and this morning I have 6.

by Diego Ercolani 19 Jan '23

ovirt-engine-appliance-4.5-20221206133948 Hello, I have some trouble with my Gluster instance where there is hosted-engine. I would like to copy data from that hosted engine and reverse to another hosted-engine storage (I will try NFS). I think the main method is to put ovirt in global-management mode, stop the hosted-engine instance, unmount the hosted-engine storage systemctl stop {vdsmd;supervdsmd;ovirt-ha-broker;ovirt-ha-agent}; hosted-engine --disconnect-storage umount /rhev/data-center/mnt/glusterSD/localhost:_glen/ and then redeploy the hosted engine with the current backup: method 1: [doesn't work; it fail the ansible script after the pause] ovirt-hosted-engine-setup --4 --config-append=/var/lib/ovirt-hosted-engine-setup/answers/answers-20230116184834.conf --restore-from-file=230116-backup.tar.gz --ansible-extra-vars=he_pause_before_engine_setup=true but it doesn't work method 2: [I cannot find the glitch] I saw in every node there is a configuration under /etc/ovirt-hosted-engine/hosted-engine.conf where there are some interessant entry: vm_disk_id=0a1a501c-fc45-430f-bfd3-076172cec406 vm_disk_vol_id=f65dab86-67f1-46fa-87c0-f9076f479741 storage=localhost:/glen domainType=glusterfs metadata_volume_UUID=4e64e155-ee11-4fdc-b9a0-a7cbee5e4181 metadata_image_UUID=20234090-ea40-4614-ae95-8f91b339ba3e lockspace_volume_UUID=6a975f46-4126-4c2a-b444-6e5a34872cf6 lockspace_image_UUID=893a1fc1-9a1d-44fc-a02f-8fdac19afc18 conf_volume_UUID=206e505f-1bb8-4cc4-abd9-942654c47612 conf_image_UUID=9871a483-8e7b-4f52-bf71-a6a8adc2309b so, the conf_volume under conf_image dir is a TAR archive: /rhev/data-center/mnt/glusterSD/localhost:_glen/3577c21e-f757-4405-97d1-0f827c9b4e22/images/9871a483-8e7b-4f52-bf71-a6a8adc2309b/206e505f-1bb8-4cc4-abd9-942654c47612: POSIX tar archive (GNU) That I think is the common configuration. I copied the structure (from 3577c21e-f757-4405-97d1-0f827c9b4e22 directory) in the new storage (nfs), changed the entries under local configuration and "shared configuration": from storage=localhost:/glen to storage=<server>:/directory (writable by vdsm user and kvm group) from domainType=glusterfs to domainType=nfs and issued: 1. hosted-engine --connect-storage <- work 2. hosted-engine --vm-start <- doesn't work because there is a complain about the not-starting ovirt-ha-agent What can I do? Is there any documentation somewhere? Diego

Bug in the engine-backup script when no attached TTY -- Easy fix
by eshwayri＠gmail.com 18 Jan '23

The output() function. This line: printf "%s\n" "${m}" It will fail if there is no attached TTY, which will set the exit code to 1, which in turn will trigger the cleanup() function notifying the engine that the backup failed. This ironically happens when it should be writing "Done." and exiting after a successful backup. Fix I used was to change it to: printf "%s\n" "${m}" >> "${LOG}" You can't assume attached TTY since a lot of people like me want to run this as part of a pre/post script to an automated backup program.

Hosted Engine No Longer Has IP Address - Help!
by Matthew J Black 17 Jan '23

17 Jan '23

Hi Guys, I've gone and shot myself in the foot - and I'm looking for some first-aid. I've managed to remove the IP Address of the oVirt Self-Hosted Engine and so have lost contact with it (don't ask how - let's just say I f*cked-up). I *think* its still running, I've got it set to DHCP, and I've got access to the Host its running on, so my question(s) is: - (The preferred method) How can I re-establish (console?) contact - I'm thinking via the Host Server and some kvm-commands, so I can issue a `dhclient` command - (The most drastic) How can I get it to reboot ie is there a command / command sequence to do this Any help would be appreciated. Cheers Dulux-Oz
