Single Node HCI upgrade procedure from CentOS7/oVirt 4.3 to CentOS8/oVirt 4.4?
by thomas＠hoberg.net 11 Nov '20

11 Nov '20

I can hear you saying: "You did understand that single node HCI is just a toy, right?" For me the primary use of a single node HCI is adding some disaster resilience in small server edge type scenarios, where a three node HCI provides the fault tolerance: 3+1 with a bit of distance, warm or even cold stand-by, potentially manual switch and reduced workload in case disaster strikes. Of course, another 3nHCI would be better, but who gets that type of budget, right? What I am trying say: If you want oVirt to gain market share, try to give HCI more love. And while you're at it, try to make expanding from 1nHCI to 3nHCI (and higher counts) a standard operational procedure to allow expanding a disaster stand-by into a production setup, while the original 3nHCI is being rebuilt. For me low-budget HCI is where oVirt has its biggest competitive advantage against vSan and Nutanix, so please don't treat the HCI/gluster variant like an unwanted child any more. In the mean-time OVA imports (from 4.3.10 exports) on my 4.4.2 1nHCI fail again, which I'll report separately.

Upgrade Problem oVirt engine 4.4.1.8-1.el8 -> 4.4.3
by Andrei Verovski 11 Nov '20

11 Nov '20

Hi ! I’m trying to upgrade oVirt engine 4.4.1.8-1.el8 to the latest 4.4.3, running as KVM appliance (not hosted engine). This sequence of commands yum install https://resources.ovirt.org/pub/yum-repo/ovirt-release44.rpm engine-upgrade-check yum update ovirt\*setup\* Results in a long list of dependency errors, short excerpt below. Looks like something (e.g. repo) is missing. How to fix this? Thanks in advance. ————— LOG ---------- Problem 1: problem with installed package ovirt-engine-ui-extensions-1.2.2-1.el8.noarch - package ovirt-engine-ui-extensions-1.2.2-1.el8.noarch requires ovirt-ansible-cluster-upgrade >= 1.1.12, but none of the providers can be installed Problem 2: package ovirt-engine-4.4.1.8-1.el8.noarch requires ovirt-engine-ui-extensions >= 1.0.4, but none of the providers can be installed - package ovirt-engine-ui-extensions-1.2.2-1.el8.noarch requires ovirt-ansible-cluster-upgrade >= 1.1.12, but none of the providers can be installed - package ovirt-engine-4.4.1.8-1.el8.noarch requires ovirt-ansible-roles >= 1.2.0, but none of the providers can be installed - package ovirt-ansible-collection-1.2.1-1.el8.noarch obsoletes ovirt-ansible-cluster-upgrade provided by ovirt-ansible-cluster-upgrade-1.2.3-1.el8.noarch

Cluster with Hosted Engine update BIOS Setting Ovirt 4.4.3
by scrik787＠gmail.com 11 Nov '20

11 Nov '20

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'. It requires a controller that accepts a pcie-root-port VDSM.log https://pastebin.com/vsAKy9rX

Host NonResponsive after migration to oVirt 4.4
by tferic＠swissonline.ch 11 Nov '20

11 Nov '20

Hi I am looking for help after my oVirt upgrade failed. I have upgraded from ovirt 4.3 to 4.4 following the instructions here: https://www.ovirt.org/documentation/upgrade_guide/#Upgrading_from_4-3 <https://www.ovirt.org/documentation/upgrade_guide/#Upgrading_from_4-3> It's a single-host (standalone engine) test environment. I wiped CentOS 7 and reinstalled a fresh CentOS 8. I installed the oVirt 4.4 repo and all the necessary software packets. I used `engine-backup --mode=restore --file=/tmp/ovirt-engine-pre-upgrade.backup --provision-all-databases` from a backup file I created before I started the upgrade. After the restore, I ran `engine-setup`. I did not get any errors during any of these steps on the console. So the upgrade could be considered successful from that perspective. After the upgrade, I login to the ovirt admin portal, and I try to "Activate" my host (was set to "Maintenance" mode before upgrade). The Activation fails with error "NonResponsive" in the GUI. Under the "bell" icon, I find the Event "Host nuc1.feric.ch is non responsive.” In /var/log/ovirt-engine/engine.log, I find the following error: ``` 2020-11-09 23:12:21,080+01 ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.GetCapabilitiesAsyncVDSCommand] (EE-ManagedScheduledExecutorService-engineScheduledThreadPool-Thread-47) [] Command 'GetCapabilitiesAsyncVDSCommand(HostName = nuc1.feric.ch, VdsIdAndVdsVDSCommandParametersBase:{hostId='d7c30cc0-ac59-4cf3-a1e7-b9fae9db83fb', vds=‘Host[nuc1.feric.h,d7c30cc0-ac59-4cf3-a1e7-b9fae9db83fb]'})' execution failed: java.net.ConnectException: Connection refused ``` `systemctl status ovirt-engine` shows that the engine is running. I am able to reboot the host from the oVirt GUI directly. Does anyone have an idea how to proceed? Many thanks Toni

Clone a VM in the User Portal
by Nicolás 11 Nov '20

11 Nov '20

Hi, We're using oVirt 4.3.8, having an organization that intensively uses the User Portal. After upgrading from 4.2, we've noticed that cloning a VM from within the User Portal is not possible anymore. In our case, this feature was heavily used by hundreds of students deploying their VMs. Is this feature in the roadmap yet? If not, do you consider it useful to open a RFE? Thank you. Regards, Nico

Cannot restore engine from 4.3.9 to 4.4.3
by tferic＠swissonline.ch 11 Nov '20

11 Nov '20

Hi I just tried to restore my engine backup taken from release 4.3.9.4 to a newer oVirt installation release 4.4.3.11. The restore process fails with a FATAL error. I was under the impression that backups from all 4.3 versions were supposed to be restorable on 4.4. My installation is a single-box all-in-one (Standalone Engine installed together with oVirt node). # engine-backup --mode=restore --file=/exports/data-t2/backups/ovirt-engine-backup-20201018124037_pre-upgrade.backup --provision-all-databases Start of engine-backup with mode 'restore' scope: all archive file: /exports/data-t2/backups/ovirt-engine-backup-20201018124037_pre-upgrade.backup log file: /var/log/ovirt-engine-backup/ovirt-engine-restore-20201111031500.log Preparing to restore: - Unpacking file '/exports/data-t2/backups/ovirt-engine-backup-20201018124037_pre-upgrade.backup' FATAL: Backup was created by version '4.3.9.4' and can not be restored using the installed version 4.4.3.11 Complete content of the restore log file: 2020-11-11 03:15:00 23143: Start of engine-backup mode restore scope all file /exports/data-t2/backups/ovirt-engine-backup-20201018124037_pre-upgrade.backup 2020-11-11 03:15:00 23143: OUTPUT: Start of engine-backup with mode 'restore' 2020-11-11 03:15:00 23143: OUTPUT: scope: all 2020-11-11 03:15:00 23143: OUTPUT: archive file: /exports/data-t2/backups/ovirt-engine-backup-20201018124037_pre-upgrade.backup 2020-11-11 03:15:00 23143: OUTPUT: log file: /var/log/ovirt-engine-backup/ovirt-engine-restore-20201111031500.log 2020-11-11 03:15:00 23143: OUTPUT: Preparing to restore: 2020-11-11 03:15:01 23143: OUTPUT: - Unpacking file '/exports/data-t2/backups/ovirt-engine-backup-20201018124037_pre-upgrade.backup' 2020-11-11 03:15:01 23143: Opening tarball /exports/data-t2/backups/ovirt-engine-backup-20201018124037_pre-upgrade.backup to /tmp/engine-backup.UAcLerghwY 2020-11-11 03:15:01 23143: Verifying hash 2020-11-11 03:15:01 23143: Verifying version 2020-11-11 03:15:01 23143: FATAL: Backup was created by version '4.3.9.4' and can not be restored using the installed version 4.4.3.11 regards, Toni Feric

Problem with Cluster-wise BIOS Settings in oVirt 4.4
by Rodrigo G. López 11 Nov '20

11 Nov '20

Hi all, We are running an oVirt 4.4 Hosted Engine as a VM, and after changing the Cluster's BIOS type from Q35 with Legacy BIOS (the default one after installation) to Preexistent, the VM fails with the following error: XML error: The device at PCI address 0000:00:02.0 cannot be plugged into the PCI controller with index='0'. It requires a controller that accepts a pcie-root-port. We need it so that we can run imported VMs from a previous version of oVirt, namely 4.0. Applying the BIOS settings individually works but as an attempt to generalize the settings we decided to apply it to the full cluster. Tell me if you need more data. Cheers, -rodri

by ozmen62＠hotmail.com 11 Nov '20

11 Nov '20

Hi, I've cretated a template which has sysprep. Every document about sysprep says use "Attach Floppy" , but we know this function has been disabled/deprecated So, when i use Run One, attach windows cdrom and put in it definitions (domain name, user credentials etc) , nothing happens. I also have correct properties and sysprep files in engine Just windows boot like it is new machine and ask lots of questions for prepare itself. Would someone please explain this? How can i run sysprep correctly?

setting routing rules for guests?
by yam yam 11 Nov '20

11 Nov '20

Hello everyone! I'm wondering there is any feature like applying routing rules for VM to reach the external network (and vice versa). and I guess it's different according to using external provider(OVN). if not, how to users usually assign floating IP to VM?? Thanks Sincerely,
