Engine backup / restore
by duparchy＠esrf.fr 20 Oct '21

20 Oct '21

Hi, I'm testing Backup / Restore of the engine. Once the engine is restored ; how to resync the engine database with the "reality" of the Storage Domains ? (I'm talking about anything that could have been done after the engine backup : Deleted / Created VMs ; Snapshots taken since the backup, etc.. I'm on 4.3, Oracle LVM context. My Tests : - Create a snapshot of some random VM. Say VM-1 - Enable that VM preview and start it on a host. - Stop OLVM engine server. - Start a full backup copy of that OLVM engine (That backup being a snapshot taken, say, yesterday. Our test OLVM engine being a VM running in another separate virltualization infrastucture.) The restored OLVM does not show the existence of the VM-1 snapshot. It only shows the VM running on the active instance. No snapshot. I tried Storage Domain / Scan disks. No refresh to be seen.

prod network glitch after reboot lab server
by Dominique D 20 Oct '21

20 Oct '21

Hi, I have two ovirt environments on the same network. 2 switches (10G switch for storage and 1G switch for data / management) 1) Prod environment: 3 oVirt 4.4.6 nodes (1 port 10G per node for storage gluster and 1 port 1G for data / management) 2) Lab environment 2 oVirt nodes 4.4.6 (1 Port 10G per node for storage gluster and 1 port 1G for data / management) The storage is on the same vlan and subnet for both environments. When I restart one of my lab servers, I have communication cuts/glitch on my production ovirt clusters. I even had server reboots. Do you know why ? Here somes log : VDSM ovnode1.telecom.lan command SpmStatusVDS failed: Connection timeout for host 'ovnode1.telecom.lan', last response arrived 42479 ms ago. Host ovnode1.telecom.lan is not responding. It will stay in Connecting state for a grace period of 88 seconds and after that an attempt to fence the host will be issued. Invalid status on Data Center Default. Setting Data Center status to Non Responsive (On host ovnode1.telecom.lan, Error: Network error during communication with the Host.). Host ovnode1.telecom.lan cannot access the Storage Domain(s) datassd attached to the Data Center Default. Setting Host state to Non-Operational.

Ovirt VM started with the most recent snapshot with the current disk missing
by Xiaoyu Hu 20 Oct '21

20 Oct '21

Dear Ovirt folks, I am faced with a very strange situation with Ovirt 4.3. A virtual machine has two snapshots and a working disk, with the former two snapshots being read only and the working one read-write. After an unplanned power outage, a virtual machine can only be started with the recent snapshot, and the actual working disk is missing in the Ovirt UI. I can see the disk still exists in the backend storage, but it seems not Ovirt does not know it. Thus the VM lose the recent data on the missing disk. Does any one know whether this is a known bug in Ovirt 4.3, or is there a method to resotre the missing working disk back to the virtuanl machine? Otherwise i am faced with a terrible data loss issue on Ovirt best regards, Samuel

GPG key <infra@ovirt.org> expired since April ?
by Fredrik Arneving 20 Oct '21

20 Oct '21

Hi, According to output pasted below it seems that the GPG key used to sign installation media has expired 2021-04-03. Why is new installation ISO signed 7 days ago with a key that has been expired for almost 6 months? Is this correct? My main question though is if this iso is authentic? $ ll -h ovirt-node-ng-installer-4.4.8-2021090310.el8.iso* -rw-r--r--. 1 fredde fredde 1.9G Oct 1 14:48 ovirt-node-ng-installer-4.4.8-2021090310.el8.iso -rw-r--r--. 1 fredde fredde 32 Oct 1 14:48 ovirt-node-ng-installer-4.4.8-2021090310.el8.iso.md5sum -rw-r--r--. 1 fredde fredde 490 Oct 1 14:48 ovirt-node-ng-installer-4.4.8-2021090310.el8.iso.md5sum.sig $ gpg --list-keys oVirt pub rsa2048 2014-03-30 [SC] [expired: 2021-04-03] 31A5D7837FAD7CB286CD3469AB8C4F9DFE590CB7 uid [ expired] oVirt <infra(a)ovirt.org> $ gpg --verify-files *.sig gpg: assuming signed data in 'ovirt-node-ng-installer-4.4.8-2021090310.el8.iso.md5sum' gpg: Signature made Thu 23 Sep 2021 02:41:24 PM CEST gpg: using RSA key AB8C4F9DFE590CB7 gpg: Good signature from "oVirt <infra(a)ovirt.org>" [expired] gpg: Note: This key has expired!

UEFI Guest can only be started on UEFI host (4.4)
by nroach44＠nroach44.id.au 20 Oct '21

20 Oct '21

Hi All, A problem I've just "dealt with" over the past months is that the two UEFI VMs I have installed (One Windows 10, one RHEL8) will only start on the oVirt Node (4.4.x, still an issue on 4.4.8) hosts that have been installed using UEFI. In the case of both guests, they will "start" but get stuck on a small 640x480-ish black screen, with no CPU or disk activity. It looks as if the VM has been started with "Start paused" enabled, but the VM is not paused. I've noticed that this matches the normal startup of the guest, although it only spends a second or two like that before TianoCore takes over. Occasionally, I'm able to migrate the VM to a BIOS host.

Power Saving schedule, hosts not shutting down
by Maton, Brett 20 Oct '21

20 Oct '21

Hi, I'm having trouble with the power_saving Scheduling Policy not shutting down idle hosts Policy is more or less default, I added 'HostsInReserve 0' too see if that would help, and then 24hrs later I bumped CpuOverCommitDurationMinutes to 15 that didn't make a difference either. (not unexpected as the CPU is only being tickled by two small VMs at the moment). 3x Dell Hosts with iDRAC 8 management cards, power management configured and functional. oVrit 4.4.8.6-1.el8 Thanks in advance for any help Brett

Assigning public IPs to a VM
by admin＠foundryserver.com 19 Oct '21

19 Oct '21

My provider will give me 20 public IP's, and attach them to each of my hosts. So a total of 60. The question I have, is I have two nics on the host, public and private. Is assigning the public IP as simple as selecting the public network and typing in one of the public IP's? I am still trying to get my hosted engine running, so at this point can't try this. Just thought I would ask in advance. Again Thank you for any help. Brad

Understanding Cluster Networking between Hosts
by admin＠foundryserver.com 18 Oct '21

18 Oct '21

Hello everyone. I am looking to setup a ovrit cluster. I am struggling with the network side of things. I have watched some videos about Ovirt and kvm/libvirt. I understand the bridge and NAT networks. The part I am struggling with is the host network. Here is my setup. I have two bare metal servers, that have one physical nic with a public IP. There is no private physical network on these boxes virtual or physical. I want to host an application on a single vm for each customer. the customer access the application via username.domain.com. So the question is. I have to have a layer 7 load balancer to route the url to an IP. This load balancer is haproxy on a separate bare metal box. (it could be in a vm on one of the hosts) So the load balancer has to be on the same network as all the vms. I just don't know to setup the networking between the LB on one box and the vm's on potentially may bare metal hosts. It really feels like I am missing something really obvious. All the videos I have watched all assume the host networking is already in place. Any help or resources I can read/watch would really be helpful. Brad

Ovirt VM started with old snapshots but with current disk missing
by samuel.xhu＠horebdata.cn 17 Oct '21

17 Oct '21

Hi, all: I have an ovirt 4.3 environment of 3 nodes. While i am using the following command (qemuCmd = 'qemu-img convert -p -c -O qcow2 '+backy2Source+' '+RESTOREPATH+disk.id) to merge qemu diks to do backup using backy2, unfortnately a power cut happened. After the power is back, the current disk disappeared in web UI and the recent data is lost when i restarted the virtual machine. But I could see the disk (44dd7a6f...) still exist, but Ovirt can not recognize it. How could i restore the disk identified by 44dd7a6f... so that ovirt can recognize it again? Anyone can help? Thanks!

HA VM and vm leases usage with site failure
by Gianluca Cecchi 17 Oct '21

17 Oct '21

Hello, supposing latest 4.4.7 environment installed with an external engine and two hosts, one in one site and one in another site. For storage I have one FC storage domain. I try to simulate a sort of "site failure scenario" to see what kind of HA I should expect. The 2 hosts have power mgmt configured through fence_ipmilan. I have 2 VMs, one configured as HA with lease on storage (Resume Behavior: kill) and one not marked as HA. Initially host1 is SPM and it is the host that runs the two VMs. Fencing of host1 from host2 initially works ok. I can test also from command line: # fence_ipmilan -a 10.10.193.152 -P -l my_fence_user -A password -L operator -S /usr/local/bin/pwd.sh -o status Status: ON On host2 I then prevent reaching host1 iDRAC: firewall-cmd --direct --add-rule ipv4 filter OUTPUT 0 -d 10.10.193.152 -p udp --dport 623 -j DROP firewall-cmd --direct --add-rule ipv4 filter OUTPUT 1 -j ACCEPT so that: # fence_ipmilan -a 10.10.193.152 -P -l my_fence_user -A password -L operator -S /usr/local/bin/pwd.sh -o status 2021-08-05 15:06:07,254 ERROR: Failed: Unable to obtain correct plug status or plug is not available On host1 I generate panic: # date ; echo 1 > /proc/sys/kernel/sysrq ; echo c > /proc/sysrq-trigger Thu Aug 5 15:06:24 CEST 2021 host1 correctly completes its crash dump (kdump integration is enabled) and reboots, but I stop it at grub prompt so that host1 is unreachable from host2 point of view and also power fencing not determined At this point I thought that VM lease functionality would have come in place and host2 would be able to re-start the HA VM, as it is able to see that the lease is not taken from the other host and so it can acquire the lock itself.... Instead it goes through the attempt to power fence loop I wait about 25 minutes without any effect but continuous attempts. After 2 minutes host2 correctly becomes SPM and VMs are marked as unknown At a certain point after the failures in power fencing host1, I see the event: Failed to power fence host host1. Please check the host status and it's power management settings, and then manually reboot it and click "Confirm Host Has Been Rebooted" If I select host and choose "Confirm Host Has Been Rebooted", then the two VMs are marked as down and the HA one is correctly booted by host2. But this requires my manual intervention. Is the behavior above the expected one or the use of VM leases should have allowed host2 to bypass fencing inability and start the HA VM with lease? Otherwise I don't understand the reason to have the lease itself at all.... Thanks, Gianluca

Engine insists on running on 1 host in cluster when that host is online
by David White 16 Oct '21

16 Oct '21

About a month ago, I completely rebuilt my oVirt cluster, as I needed to move all my hardware from 1 data center to another with minimal downtime. All my hardware is in the new data center (yay for HIPAA compliance and 24/7 access, unlike the old place!) I originally built the cluster as a single-node hyperconverged. I then added nodes to it, and then, finally, I reconfigured gluster to run in a replica 2 / arbiter 1 configuration. As of now: - I have 4 compute hosts - Gluster is running fine and replicating fine between the two full replicas, along with the arbiter node - I need to revisit my recent email about gluster replication speed, though However, I'm worried about two things: - I think that my hosts, and hosted-engine, are all still configured to use the single mount point from the original single-node hyperconverged ... i.e. if I shutdown / reboot that host, then the storage "goes away" - How do I reconfigure oVirt to use the 2nd replica as a secondary mount point? - Currently, the Engine is deployed on two of the servers (a and c). But any time one of those servers is online (c), the hosted-engine insists on running on that server c. I cannot migrate the engine off of c. And if the engine is running on the other host a, then I turn host c back on, the engine shuts down from a, and comes back up on c. - How do I "fix" this so that the engine will run on host a, even when host c is turned on? - How do I deploy the hosted-engine to host b? - Is it as simple as logging into host b, and running "hosted-engine --deploy" ?

15 Oct '21

Sometimes, some vm failed to stop it by press the shutdown button on the management portal, it will show such message in log: shutdown of vm *** failed. And I want to know: 1. why cannot shutdown it normally ? 2. what difference between the shutdown and power off ? (For example, what are the different signals sent to the QEMU process) Thanks.

How to add a note to a VM
by Gianluca Cecchi 12 Oct '21

12 Oct '21

Hello, I know there are the "Comment" and "Description" columns available in many areas of the Webadmin Gui. But there are some tasks, like "shutdown VM" or "Management -> Maintenance" for a host, where I can specify a "reason" for doing that task and then a note icon appears, aside the object, with the mouse over showing the note text, like in this image: https://drive.google.com/file/d/1v3Yd2t7AtuRFMT6HPFYYZqYUmJLMHYMY/view?usp=… Is there a way to do it in general? So for example I have a VM and I want to put a note (for some colleague, or to remind me to do an action tomorrow, ecc...) And btw: how can I manually remove the note? Eg I shutdown a VM and fill in the "Reason" field and then in a second moment I want to remove it.... Thanks in advance, Gianluca

Re: fresh hyperconverged Gluster setup failed in ovirt 4.4.8
by Ax Olmos 10 Oct '21

10 Oct '21

The problem is that the ‘glusterd_brick_t’ file context is missing from selinux-policy-targeted 3.14.3-80 on CentOS 8 Stream. It exists in the CentOS 8.4 version: rpm -qpl selinux-policy-targeted-3.14.3-67.el8_4.2.noarch.rpm | grep gluster /usr/share/selinux/targeted/default/active/modules/100/glusterd /usr/share/selinux/targeted/default/active/modules/100/glusterd/cil /usr/share/selinux/targeted/default/active/modules/100/glusterd/lang_ext /var/lib/selinux/targeted/active/modules/100/glusterd /var/lib/selinux/targeted/active/modules/100/glusterd/cil /var/lib/selinux/targeted/active/modules/100/glusterd/hll /var/lib/selinux/targeted/active/modules/100/glusterd/lang_ext Not on CentOS 8 Stream: rpm -qpl selinux-policy-targeted-3.14.3-80.el8.noarch.rpm | grep gluster You can remove the selinux checks from: /etc/ansible/roles/gluster.infra/roles/backend_setup/tasks/mount.yml but I’m not sure of the implications of that. This is a show stopper for oVirt and someone from oVirt needs to contact the CentOS 8 Stream maintainers and have them put the selinux context back, or come up with some other workaround.

Slow gluster replication
by David White 10 Oct '21

10 Oct '21

I can't remember if I've asked this already, or if someone else has brought this up. I have noticed that gluster replication in a hyperconverged environment is very slow. I just (successfully, this time) added a brick to volume that was originally built on a single-node Hyperconverged cluster. One of my volumes has over 600GB, but the network is 10Gbps, so replication really shouldn't take that long. It's been over two hours, and that volume has only replicated a little over 400GB. It feels like it's taking about 1GB every 30 seconds - 1 minute or so... Why would this replication be so slow? Sent with ProtonMail Secure Email.

Configuring LUNS for self-hosted engine install
by Virden, Gerald 08 Oct '21

08 Oct '21

Hi, I have a host with two 16TB LUNS that I want to deploy a self-hosted engine on. I have so far been unsuccessful; the install either fails or hangs and Oracle is saying it is due to storage. I can see both LUNS with multipath -ll. Does anyone know of step by step instructions on what to do to configure the LUNS so the engine will see them and set up the storage domain? Jerry

Re: fresh hyperconverged Gluster setup failed in ovirt 4.4.8
by Eddie Garcia 07 Oct '21

07 Oct '21

I have been having this issue as well with no solution working but I came across something interesting. In selinux-policy 3.14.3-77 they removed the glusterd selinux module. https://centos.pkgs.org/8-stream/centos-baseos-x86_64/selinux-policy-3.14.3… so that policy doesn exist anymore for ansible to apply. I plan on testing installing an older version into an ovirt node box to test which defaults as of 4.4.8 to selinux-policy version 3.14.3-79.el8. A clean install of CentOS 8 using latest iso has version 3.14.3-67.el8_4.2 and I can verify that manually setting policy with command 'semanage fcontext -a -t glusterd_brick_t "/gluster_bricks(/.*)?"' is completed successfully.

However, since this upgrade VMs based on Kali no longer report their IP address to oVirt (and therefore timeout during provisioning). If I interact with the VM console, the VM does have an IP address, and the agent is running, yet oVirt reports N/A IP address. I've tried restarting the agent, but that does not help. If I load the console and use the VM it seems to increase the chances the IP address will eventually makes it's way to oVirt, although I can't seem to reproduce an update, or get it to provide the IP address on boot so that provisioning works reliably. > > Any suggestions would be really appreciated. > > Might be the same as/related to https://bugzilla.redhat.com/show_bug.cgi?id=1981946<https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fbugzilla.…> which is still being investigated > > > Thank you. > > Cheers, > Cliffe. > _______________________________________________ > Users mailing list -- users(a)ovirt.org<mailto:users@ovirt.org> > To unsubscribe send an email to users-leave(a)ovirt.org<mailto:users-leave@ovirt.org> > Privacy Statement: https://www.ovirt.org/privacy-policy.html<https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.ovirt…> > oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/<https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.ovirt…> > List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/FFINLLXPBRKYH…<https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Flists.ovi…> > To view the terms under which this email is distributed, please go to:- > https://leedsbeckett.ac.uk/disclaimer/email -- Tomáš Golembiovský <tgolembi(a)redhat.com>

Import ISCSI target as data domain, cannot see old data
by joyzhao93＠gmail.com 06 Oct '21

06 Oct '21

Hi Team, Hope you are doing well. I had a standalone Ovirt Engine with 2 hosts, one 2TB ISCSI data domain (dell equallogic). Today the Ovirt Engine machine crashed so we have to bring up a new one, setup is good and when I try to import ISCSI data domain I can see volumes/Luns, but after import, Ovirt shows the volume is empty - 2TB free (so all old data on the ISCSI volume is not presenting). However when I login to the ISCSI target machine, it shows the old data (around 400GB) is in use. Seems like the new Ovirt Engine cannot detect the old ISCSI data domain disk content. Thank you, Sincerely, SYZhao

Deploying ovirt+gluster hyperconverged with standalone engine
by J W 06 Oct '21

I'm looking for the proper steps to deploy ovirt+gluster hyperconverged with standalone engine as the scenario doesn't seem to be covered here: https://www.ovirt.org/documentation/gluster-hyperconverged/chap-Deploying_H… I have attempted to: 1) Deploy standalone engine 2) deploy 3 nodes and ran gluster deployment, stopping before the engine deploy 3) Added hosts to standalone engine I then attempt to add the gluster volumes to the standalone engine by specifying host1:/volume as glusterfs but the volume does not successfully add. Is there another perferred method for this type of deployment?

Hi oVirt Team, Reading the API docs http://ovirt.github.io/ovirt-engine-api-model/4.3/#services/external_vm_imp… http://ovirt.github.io/ovirt-engine-api-model/4.3/#types/external_vm_provid… and ovirt_vm module https://docs.ansible.com/ansible/latest/collections/ovirt/ovirt/ovirt_vm_mo… I see support for - kvm - vmware - XEN In the oVirt web GUI (4.3) there is under compute -> VM -> import -> source options for: - kvm - vmware - XEN - Virtual Appliance OVA I'm trying to import an OVA that sits on the file system on the oVirt node. Via the GUI selecting Virtual Appliance OVA does the job. Is the API missing this functionality or am I missing something? -- Divan Santana

transparent huge pages are not used on vm and physical host. But, can I enable hugepage memory on virtual machines but not on a physical machine?

For some virtual machines, 4G memory is enough, while for some virtual machines, 64GB memory is needed.

qemu-guest-agent not reporting IP address on boot?
by c.schreuders＠leedsbeckett.ac.uk 04 Oct '21

04 Oct '21

Hi folks, Kali Linux repos (based on Debian) no longer ship ovirt-guest-agent, and instead package qemu-guest-agent. However, since this upgrade VMs based on Kali no longer report their IP address to oVirt (and therefore timeout during provisioning). If I interact with the VM console, the VM does have an IP address, and the agent is running, yet oVirt reports N/A IP address. I've tried restarting the agent, but that does not help. If I load the console and use the VM it seems to increase the chances the IP address will eventually makes it's way to oVirt, although I can't seem to reproduce an update, or get it to provide the IP address on boot so that provisioning works reliably. Any suggestions would be really appreciated. Thank you. Cheers, Cliffe.

You have to reinstall the node that you isolated with the engine. So after taing the engine at its latest 4.3.x level and rebooting the 4.3 engine OS, you have to follow the steps described in 6.5: stop the ovirt-engine service, take a backup and copy the generated file outside of the env, scratch the engine and related node and reinstall it with 4.4 ovirt node and then on the host, now in 4.4, run the command hosted-engine --deploy --restore-from-file=backup.bck and so on...

Allowing Grafana to connect to oVirt DWH database (Data Warehouse) Login to the oVirt engine 4.3 and create a user "grafana" with password "grafana" that will get a read-only access to the ovirt_engine_history database and will be able to use public schema # su - postgres -c 'scl enable rh-postgresql10 bash' # psql -U postgres -c "CREATE ROLE grafana WITH LOGIN ENCRYPTED PASSWORD 'grafana';" -d ovirt_engine_history # psql -U postgres -c "GRANT CONNECT ON DATABASE ovirt_engine_history TO grafana;" # psql -U postgres -c "GRANT USAGE ON SCHEMA public TO grafana;" ovirt_engine_history Generate the rest of the permissions that will be granted to the newly created user and save them to a file: # psql -U postgres -c "SELECT 'GRANT SELECT ON ' || relname || ' TO grafana;' FROM pg_class JOIN pg_namespace ON pg_namespace.oid = pg_class.relnamespace WHERE nspname = 'public' AND relkind IN ('r', 'v');" --pset=tuples_only=on ovirt_engine_history > grant.sql Use the file you created in the previous step to grant permissions to the newly created user: # psql -U postgres -f grant.sql ovirt_engine_history Remove the file you used to grant permissions: # rm grant.sql Exit the postgres user shell by pressing Ctrl+d Add the following lines for the newly created user to /var/opt/rh/rh-postgresql10/lib/pgsql/data/pg_hba.conf preceding the line beginning local all all host ovirt_engine_history grafana 0.0.0.0/0 md5 host ovirt_engine_history grafana ::0/0 md5 Reload postgres service # systemctl reload rh-postgresql10-postgresql 2. Installing Grafana You can install Grafana directly on the oVirt Engine machine (this is how it's done in oVirt 4.4) or on a separate machine. Following steps shows how you can install Grafana on a Oracle Linux 7 server. Note: Oracle provides Grafana in the OLCNE yum repository - you only need to install the repository definition package to pickup Grafana and it's dependencies. # yum install oraclelinux-release-el7 # yum install oracle-olcne-release-el7 # yum-config-manager --enable ol7_optional_latest ol7_olcne11 # yum install grafana # systemctl enable --now grafana-server 3. Adding oVirt DWH database as Data Source in Grafana Login to Grafana (default port 3000) and navigate to Configuration -> DataSources and click on Add Data Source button. Select PostgreSQL source and use the following settings (adjust the Host IP address to match your oVirt Engine IP but do not change the Name): Name: oVirt DWH Host: your-engine-ip-address:5432 user: grafana pass: grafana SSL mode: disable 4. Importing Dashboards from oVirt 4.4 Download Grafana Dashboards from oVirt 4.4 repository: https://github.com/oVirt/ovirt-dwh/tree/master/packaging/conf/grafana-dashb… You can now import them in Grafana by navigating to Create -> Import and clicking on Upload .json file or by simply pasting JSON content. I've tested this on my OLVM/oVirt 4.3 and works perfectly well. Have fun!

I am looking into guidelines, how to, for setting up Grafana using DataWarehouse as data source. Did anyone already did this, and would be willing to share the steps? AFAIU this is definitely not tested/recommended/supported, but the current (4.4) dashboards use only 4.3 dwh compatibility views. So in theory, 4.4 grafana setup can work against your 4.3 engine/dwh without problems. So you can try something like: 1. Install el8 on some machine 2. Install ovirt-release (4.4!) 3. Install ovirt-engine-dwh-grafana-integration-setup. I *think*, didn't try, that it would carry with it all the dependencies it needs. 4. Run engine-setup. When prompted, only accept "Configure grafana?", and reply "No" to everything else 5. Follow the other prompts as applicable This should be enough. Not sure about the commands to add SSO on the engine machine. Perhaps better verify this first against a test engine (can be on another el7/ovirt4.3 VM with no hosts). But, repeating: this isn't recommended. Did you consider upgrading only your engine, and keep your hosts 4.3 until you can upgrade them later?

Live domain migration breaks Windows (UEFI) vitrual machine
by Patrick Lomakin 02 Oct '21

02 Oct '21

Greetings! I've already mentioned the problem of live disk migration between different storage domains, but yesterday I found the same problem in a new oVirt installation. My actions after deploying oVirt are: 1) Created a storage domain (iSCSI and Gluster); 2) Created a virtual machine with Windows 10 (UEFI); 3) Placed the virtual machine on the Gluster domain; 4) Started the virtual machine and started moving the disk from the Gluster storage domain to iSCSI. The disk move process was successful and error free and the virtual machine worked. However, after a reboot, the machine no longer started. The boot goes into recovery mode. All attempts to restore the machine to work were unsuccessful. I want to note that this does not happen if the machine was turned off during the disk move. In this case, it starts up without any problems. The type of domain from or to which the disk is migrated does not important. In case of live migration the Windows (UEFI) VM crashes in any case.

You guys scare me. Seriously. I'm trying to update from oVirt 4.3 to 4.4 using a self-hosted engine. All VMs on the host are migrated off, other than the hosted engine, from the first host I intend to update to EL 8.4, per the documentation. I installed the RPM from here: https://resources.ovirt.org/pub/yum-repo/ovirt-release44.rpm I'm configuring the Engine following the upgrade document located here: https://www.ovirt.org/documentation/upgrade_guide/index.html#SHE_Upgrading_… Step 6.4, after installing the oVirt 4.4 RPM on the engine: engine-upgrade-check - I get this response: [root@labmanager yum.repos.d]# engine-upgrade-check VERB: queue package ovirt-engine-setup for update VERB: Downloading: ovirt-4.3-epel/x86_64/metalink (0%) VERB: Downloading: ovirt-4.3-epel/x86_64/metalink 10 k(100%) FAIL: Cannot queue package ovirt-engine-setup: Cannot find a valid baseurl for repo: ovirt-4.4/7 OK: Performing yum transaction rollback Error: Cannot find a valid baseurl for repo: ovirt-4.4/7 Doing a 'yum update' to just validate yum is working correctly, after installing the 44 RPM, I get this: Cannot find a valid baseurl for repo: ovirt-4.4/7 Any advice? Is the repo just not valid at the moment? Did someone forget to run a 'createrepo' after updating the YUM/DNF repo?
