Self Hosted Engine a single Bare Metal Server
by LS CHENG 19 Nov '20

19 Nov '20

Hi We are planning to set up a single ovirt node for testing. It is a single Bare Metal Server. I wonder if there is any problem setting up a Self Hosted Engine in this Bare Metal (there is no HA but we don't need it in this case)? I know it is probably not the best practice but it is for training and testing purposes. Thank you

Fix corrupt self-hosted engine
by Alex K 19 Nov '20

19 Nov '20

Hi all, I have a corrupt self-hosted engine (with several file system errors, postgres not able to start) and thus it does not give access to the web UI. This happened following an unlucky split brain resolution (I am running 2 nodes). The two hosts are running VMs also which I would like to keep running as they are needed. When trying to boot into rescue mode (using systemd.unit=emergency.target boot parameter) I get a cursor and nothing else. I have backups of engine files with scope all (using the engine-backup tool). What is the best approach to try and fix the engine or redeploy. Thanks for any help. Alex

I logged onto oVirt this morning, and I see the node is in a “Unassigned” state. I can ping it, but cannot SSH, so there is something that is causing the host to be unresponsive. On Saturday after I sent the mail, I opened a console to the node, and I saw the below entries before logging in: audit:backlog limit exceeded I the tried the solution of increasing the buffer size in the audit.rules file in /etc/audit/rules.d/ , as per below, but it did not resolve the issue. ## First rule - delete all -D ## Increase the buffers to survive stress events. ## Make this bigger for busy systems -b 8192 ## Set failure mode to syslog -f 1 Is it possible to upgrade the node to 4.4 while the engine is still on 4.3?

How to create a backup in event of hardware failure of a single hosted engine?
by ernestclydeachua＠gmail.com 18 Nov '20

18 Nov '20

Hello everyone, Currently we have a single bare metal that hosts oVirt and glusterFS which later on to be converted to a 3 nodes for HCI, currently another bare metal is coming this week and was planning to initially create it as a backup. is it possible to deploy a new hosted engine then create a gluster volume for 1st one as a backup domain then attach it to the new one if hardware failure occurred, or there is another kind of setup that can be done?

Migration VM
by tiziano.pacioni＠par-tec.it 18 Nov '20

18 Nov '20

Hi, I installed a new server, using the ovirt iso, with the target of migrating the VMs coming from another cluster, contained on another ovirt node. I tried to migrate a vm using the Export Domain, once imported on the new node, i see the vm from web dashboard but, from command line “virsh list --all” is absent, the imported vm does not appear in the list. Also if I try to start it, I get the following error: VM X is down with error. Exit message: unsupported configuration: bus must be 0 for ide controller. Can you help me?

Re: Hosted Engine can't migrate

Hi Bradley, usually this is not supposed to happen. I can propose you a fast fix: - Set a node into maintenance (via the UI) and then from the "Installation" drop down menu (upper right) click "reinstall" There is a tab for the HostedEngine and you have to mark it as deployed/installed If it doesn't work,ssh to one of the hosts and provide the output of: hosted-engine --vm-status Best Regards В сряда, 18 ноември 2020 г., 08:08:36 Гринуич+2, McNamara, Bradley <bradley.mcnamara(a)seattle.gov> написа: I'm new to oVirt, but not new to virtualization technologies.

Thanks. :-) > If you go in Compute --> Hosts in web admin gui, do the added hosts have a crown icon on the left of their "Name" column? If not, when you added them possibly you overlooked the "Hosted Engine" section in the window, where by default, if I'm not wrong, the value is "None": that means that the added host doesn't contributed to be one of the "Hosted Engine" ones electable to host the engine VM, but only an hyoervisor. Long time ago I opened two bugzillas about this default with some notes for improving a better experience.... If this is the case, you can remove the hosts one by one and add them again selecting "Deploy" in the Hosted Engine section, for how many you would like to contribute to the score and to be able to host the hosted engine VM. HIH, Gianluca

ovirt-shell SSL Error
by FRIES, Dirk, SHS Informatik 17 Nov '20

17 Nov '20

Hello there, I am trying to connect via ovirt-shell to my ovirt manager. To do this I've downloaded the CA File (https://127.0.0.1/ovirt-engine/services/pki-resource?resource=ca-certificat…) to /tmp and set up my config in .ovirtshellrc : [cli] autoconnect = True autopage = True [ovirt-shell] username = adminuser renew_session = False timeout = None extended_prompt = False url = https://127.0.0.1/api insecure = False kerberos = False filter = False session_timeout = None ca_file = /tmp/pki-resource?resource=ca-certificate dont_validate_cert_chain = True key_file = None password = somepassword cert_file = None So when I am trying to connect I get the following error: (60, "Peer's certificate issuer has been marked as not trusted by the user.") While researching I also found a pretty similar issue here https://lists.ovirt.org/archives/list/users@ovirt.org/thread/IYG6AQPII25366… but unfortunally there is no solution posted. Does anyone have a hint for me what could cause this problem or where to look else ? Thanks a lot ! Bye, Dirk

Re: VM with illegal snapshots
by Florian Schmid 17 Nov '20

17 Nov '20

Hi, I have also sometimes the issue with snapshots or disk move, which is also related to snapshots, when the engine process is running for a longer time. After restarting the engine service, then it is working again for several weeks, until it gets too long and issues starting again to happen. I had never the time to dig in deeper here and I'm never on a version, which is still supported, but it would be nice to here, if you maybe have the same issue? How long was your engine process running, until the issues have started?

November 2020 10:37:24 Betreff: [ovirt-users] Re: VM with illegal snapshots Hello We have the same issue, and not just one VM, we have about 10-15 VMs that have either snapshots that are illegal or snapshots that is not possible to remove. This have been an issue for quite some time, all since beginning of 4.3 we get "vm with illegal snapshots" almost every week, and most often we can remove the snapshot and all is ok, but now this have escalated quite much and leaves us with customer VM that we may not be able to reboot or that the disk gets corrupted, that have happed a few times. This is the VM with most snapshots that we are unable to remove any of them. Engine is on 4.3.10 and hosts on 4.3.9 How can i safely remove these snapshots? (I am not super comfortable around database "hacking" so some informative description would be much appreciated.) And how can we eliminate that these things happen?

Really slow manager node
by Nicolás 17 Nov '20

17 Nov '20

Hi, We're running oVirt 4.3.8 and even if this is a problem we've had since a lot of time (I would say since 4.0.x), I decided to look for help in case anything can be done. Our environment is heavily used by users in our University (about 3000 users), and currently our oVirt infrastructure has 1928 virtual machines, being 882 of them currently running. We have a separate physical machine for the manager node, and the problem is that this machine is very, very, very slow, despite it has (from my point of view) enough physical resources to run efficiently. By slow I mean even the SSH access to it takes about 10 seconds, not just the admin/user portals. Any operation takes enough time to make the experience not comfortable to our users (enter the VM portal, start a VM, open a console...). Node machine's parameters are: 18GB of RAM memory 1 processor with 12CPUs 300GB SCSI Disk, local storage. No Storage Domain is stored in this node machine. Currently, most consuming processes are: 28802 ovirt 20 0 3302876 1,5g 25988 S 1,0 8,7 22:46.36 ovirt-engine -server -XX:+TieredCompilation -Xms1024M -Xmx1024M -Xss1M -Djava.aw+ 28701 ovirt 20 0 5465432 807704 13140 S 5,9 4,4 3:15.53 ovirt-engine-dwhd -Dorg.ovirt.engine.dwh.settings=/tmp/tmp8wtnTA/settings.proper+ # free -m total used free shared buff/cache available Mem: 17886 6669 2734 255 8482 10625 Swap: 6143 1002 5141 There are also a lot of postgresql processes: postgres 2186 0.0 0.0 261812 4136 ?

easy way to migrate to new engine
by jb 17 Nov '20

17 Nov '20

Hello everybody! At the moment I have here a standalone engine and two nodes. Storage type is NFS. Now I want to setup a 3 node self hosted cluster with Glusterfs and import my VMs from the old engine. I know, there is a guide for migration from standalone to self-hosted engine, but there is so many changes (new Subnet/DNS names, different type of storage, new CPU type) that I would like to skip this migration guide. Is there a different way to migrate my VMs? Mounting my old storage and moving the disks to the Gluster would be nice, but I guess I can not just mount a storage with existing VM images. Best regards Jonathan

PLEASE HELP I changed the type in the cluster and now my hosted-engine machine won't start!. There are no backups. How can I manually change the parameters of the machine from under the roof so that it starts and I can restore ovirt to work Error in logs: XML error: The device at PCI address 0000:00:02.0 cannot be plugged into the PCI controller with index='0'.

Migrate old storage domains to new oVirt
by Joris Dobbelsteen 16 Nov '20

16 Nov '20

Hi All, I still have a single-node (all-in-one) oVirt 3.5 setup that has worked great and uses a local storage domain. I’m migrating to oVirt 4.4 hosted setup as I need to replace disks. However, since this is a single node setup, making the migration a bit tricker than usual. My plan is to move the physical disks over, mount the old local storage domains and use them in oVirt 4.4. E.g. to move the images. Is this still possible with old domains? Or is there something special that should be taken care of? Since the original domains are local is this something to take care of? E.g. can hosted engine setup be running on a “local” datacentre? Best regards, Joris Dobbelsteen

oVirt Node Crash
by Anton Louw 16 Nov '20

16 Nov '20

Hi Everybody, I have built a new host which has been running fine for the last couple of days. I noticed today that the host crashed, but it is not giving me a reason as to why. It happened at 13:45 today, but I have given time before that on the logs as well. Is there something I am missing here? Thanks Anton Louw Cloud Engineer: Storage and Virtualization ______________________________________ D: 087 805 1572 | M: N/A A: Rutherford Estate, 1 Scott Street, Waverley, Johannesburg anton.louw(a)voxtelecom.co.za www.vox.co.za

Backporting of Fixes
by Gillingham, Eric J (US 393D) 15 Nov '20

15 Nov '20

I'm still running on oVirt 4.3 due to some hardware that will require some extra effort to move to 4.4 we're not quite ready to do yet, and am currently hitting what I believe to be https://bugzilla.redhat.com/show_bug.cgi?id=1820998 which is fixed in 4.4. I'm wondering if there's a process to request a backport, or should I just open a new bug against 4.3? Thank You - Eric

oVirt 4.4 vnic profile to substitute vdsm mac spoof hook
by Gianluca Cecchi 15 Nov '20

15 Nov '20

Hello, I have an Openstack Queens environment that is composed by VMs inside oVirt. Initially this oVirt environment was on 4.3 and on director I had to set vdsm mac spoof to be able to give dhcp address to the overcloud nodes. I tried something at that time with vnic profiles but I was not able to have it work as expected, so I used the hook. Now I have migrated this same environment to 4.4.2 and I see that vdsm mac spoof is no more an option: https://bugzilla.redhat.com/show_bug.cgi?id=1703840 I tried some combinations of vnic profiles on director vnic but it seems not to work as a dhcpserver as before. I see DHCPDISCOVER from overcloud node in director messages (while before I saw DHCPREQUEST), I see the DHCPOFFER from director, but I don't see the DHCPACK from the overcloud node... On director I have the br-ctlplane vswitch using its interface eth1: ovs-vsctl show . . .

Thanks for any insight. Gianluca
