oVirt + TrueNAS: Unable to create iSCSI domain - I am missing something obvious
by David Johnson 20 Jan '23

20 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.

unsynced after remove brick
by Dominique D 19 Jan '23

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.

4.5.4 Hosted-Engine: change hosted-engine storage
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

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

Preferred way to give customer access to VMs
by hanisirfan.work＠gmail.com 16 Jan '23

16 Jan '23

Hi. Just for an introduction, I'm a junior staff working on a way to deploy a KVM cluster to provision VMs to our customer. Before this, we're using VMware ESXi and connect it to OpenNebula as the console that we give to customers. We're moving to KVM due to VMware licensing cost. I've successfully deployed an oVirt cluster and currently able to access it remotely via a VPN that I've setup on a virtualized pfSense VM inside the cluster. My question is, what is the best way to give customer console access to the VMs that we provisioned for them? Surely we doesn't want to give them access to our VPN for security reasons. I can't seems to find a way to connect OpenNebula with oVirt and I do believe it isn't possible since both are basically virtualization manager, managing the KVM instances. Thanks for the responses and ideas given ☺️

I would like to inquire about doing DR solutions Active-Passive.

I would like to try a lab to test the DR solution, and would like to know how to provision resources. So what is storage replicate? Is it hardware storage?
