install python package ovirt_imageio for Ovirt 4.3
by Grace Chen 21 Oct '21

21 Oct '21

I want to use python script running from a host to automate the remote kvm manager's vm backup. Our ovirt version is 4.3. I have installed ovirt-imageio-daemon on the host I tried to yum install ovirt-imageio-client (we use yum), it couldn't find the package. error message: Loaded plugins: ulninfo, vdsmupgrade, versionlock ovirt-4.3 | 3.0 kB 00:00:00 ovirt-4.3-extra | 3.0 kB 00:00:00 ovirt-master-snapshot | 3.0 kB 00:00:00 ovirt-master-snapshot-static | 3.0 kB 00:00:00 No package ovirt-imageio-client available. I tried to copy folder ovirt_imageio from ovirt-imageio to my python library directory, it could not compile the c file "ioutil.c" Can anybody help me install the python package? Am I installing on the correct place, do I need to use the python script only on the host that installed the kvm manager?

oVirt 4.4.8 Hyperconverged deploy failed
by dvx.mellin＠gmail.com 21 Oct '21

21 Oct '21

Hi everyone, I'm trying to deploy a hyperconverged ovirt cluster, but the the wizard in cockpit failed at the first step with the error "FQDN is not reachable". The goal is to have 3 nodes, with hosted engine on gluster FS. Here is the relevant information : - CentOS 8.4 - ovirt 4.4.8 - 2 network interfaces (1 for storage, 1 for production) The packages installed : cockpit-ovirt-dashboard, vdsm-gluster, ovirt-host, ovirt-engine-appliance, gluster-ansible-roles # rpm -qa | grep ovirt ovirt-imageio-client-2.2.0-1.el8.x86_64 ovirt-host-dependencies-4.4.8-1.el8.x86_64 ovirt-vmconsole-1.0.9-1.el8.noarch python3-ovirt-setup-lib-1.3.2-1.el8.noarch ovirt-provider-ovn-driver-1.2.34-1.el8.noarch ovirt-host-4.4.8-1.el8.x86_64 ovirt-vmconsole-host-1.0.9-1.el8.noarch ovirt-imageio-daemon-2.2.0-1.el8.x86_64 ovirt-hosted-engine-ha-2.4.8-1.el8.noarch ovirt-hosted-engine-setup-2.5.3-1.el8.noarch ovirt-engine-appliance-4.4-20210826223909.1.el8.x86_64 cockpit-ovirt-dashboard-0.15.1-1.el8.noarch python3-ovirt-engine-sdk4-4.4.15-1.el8.x86_64 ovirt-ansible-collection-1.6.2-1.el8.noarch ovirt-imageio-common-2.2.0-1.el8.x86_64 I didn't use the ovirt44-release package because we have to use our local repo. So we have cloned all necessary repo. Every package installation was passed without any issues. The /etc/hosts contains every FQDN/IP for the storage network (which is not exposed to the public), and the DNS server is reachable to respond to public FQDN. Passwordless connection is installed and works perfectly with sotrage and production FQDN. If you need more information, please tell me. Thanks in advance for your help. Regards

[ANN] oVirt 4.4.9 is now generally available
by Sandro Bonazzola 21 Oct '21

21 Oct '21

oVirt 4.4.9 is now generally available The oVirt project is excited to announce the general availability of oVirt 4.4.9 , as of October 20th, 2021. This release unleashes an altogether more powerful and flexible open source virtualization solution that encompasses hundreds of individual changes and a wide range of enhancements across the engine, storage, network, user interface, and analytics, as compared to oVirt 4.3. Important! Known issues Please note qemu-kvm, shipped outside oVirt, is affected by BZ#1999141 <https://bugzilla.redhat.com/show_bug.cgi?id=1999141> - migration fails with: "qemu-kvm: get_pci_config_device: Bad config data: i=0x9a read: 3 device: 2 cmask: ff wmask: 0 w1cmask:0" It has been detected to wait for a fix before building oVirt Node update as it includes qemu-kvm. If you haven’t updated to qemu-kvm 6 yet please don’t update it. Upgraded systems will NOT be able to migrate VMs anywhere else, not even once the issue is fixed. Important notes before you install / upgrade Please note that oVirt 4.4 only supports clusters and data centers with compatibility version 4.2 and above. If clusters or data centers are running with an older compatibility version, you need to upgrade them to at least 4.2 (4.3 is recommended). Please note that in RHEL 8 / CentOS 8 several devices that worked on EL7 are no longer supported. For example, the megaraid_sas driver is removed. If you use Enterprise Linux 8 hosts you can try to provide the necessary drivers for the deprecated hardware using the DUD method (See the users’ mailing list thread on this at https://lists.ovirt.org/archives/list/users@ovirt.org/thread/NDSVUZSESOXEFJ… ) Documentation - If you want to try oVirt as quickly as possible, follow the instructions on the Download <https://ovirt.org/download/> page. - For complete installation, administration, and usage instructions, see the oVirt Documentation <https://ovirt.org/documentation/>. - For upgrading from a previous version, see the oVirt Upgrade Guide <https://ovirt.org/documentation/upgrade_guide/>. - For a general overview of oVirt, see About oVirt <https://ovirt.org/community/about.html>.

Host is not added in known_hosts
by admin＠foundryserver.com 20 Oct '21

20 Oct '21

ok I am setting up the gluster file system. I have the following completed - able to ssh into all three hosts from host1 without password prompting. - on each host I have host file entries for host{x}.private.net - on public dns, I have host{x}1.fg.net - each host has a public nic and private nic. - I have all three hosts added in the dashboard - I am able to ping all three on private and public nic from host1 When I go to add the hosts in the setup, it looks like 2 and 3 are fine with no errors, but host1 entry gives me "Host is not added in known_hosts" error. I am doing this setup from host1. It feels like there is a link to being on host1 and host1 having the error. I am still google fooing as we speak to try and find an error. The only thing I have not done, is setup host 2 and 3 to be able to ssh into all the other boxes. Any thoughts would be greatly appreciated. Happy to share screen shots if it would help. Brad

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.).

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?

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. When it fails, the following is seen on the /sending/ host: 2021-09-21 20:09:42,915+0800 ERROR (migsrc/86df93bc) [virt.vm] (vmId='86df93bc-3304-4002-8939-cbefdea4cc60') internal error: qemu unexpectedly closed the monitor: 2021-09-21T12:08:57.355188Z qemu-kvm: warning: Spice: reds.c:2305:reds_handle_read_link_done: spice channels 1 should be encrypted 2021-09-21T12:08:57.393585Z qemu-kvm: warning: Spice: reds.c:2305:reds_handle_read_link_done: spice channels 3 should be encrypted 2021-09-21T12:08:57.393805Z qemu-kvm: warning: Spice: reds.c:2305:reds_handle_read_link_done: spice channels 4 should be encrypted 2021-09-21T12:08:57.393960Z qemu-kvm: warning: Spice: reds.c:2305:reds_handle_read_link_done: spice channels 2 should be encrypted 2021-09-21T12:09:40.799119Z qemu-kvm: warning: TSC frequency mismatch between VM (3099980 kHz) and host (3392282 kHz), and TSC scaling unavailable 2021-09-21T12:09:40.799228Z qemu-kvm: error: failed to set MSR 0x204 to 0x1000000000 qemu-kvm: ../target/i386/kvm/kvm.c:2778: kvm_buf_set_msrs: Assertion `ret == cpu->kvm_msr_buf->nmsrs' failed.

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

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" ?

cannot stop vm normally
by Tommy Sway 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.
