Upgrade from 4.3.5 to 4.3.10 HE Host issue
by Vrgotic, Marko 03 Mar '21

03 Mar '21

Hi oVirt, Yesterday I upgraded one of my oVIrt platform from 4.3.5 to 4.3.10. Platform has 10Hosts with 3Hosts as Hosts for HA. Before upgrade, all three Hosts were acknowledged Hosts for HE (little happy crown). Pre upgrade: Host1 – HE available host Host2 – HE current host Host3 – HE available host Upgraded first HE to 4.3.10, than started with HE Hosts – post upgrade of Host2, the crown disappeared and did not show up. This happens sometimes, and I usually reinstall the host, than execute HE UNDEPLOY and DEPLOY, which fixes the state. However, this time, after such actions, the server is still not an acknowledged HE host – no crown. However, if I try to remove it, oVIrt says that looks like HE is deploy on it and need to be removed, but command “hosted-engine –vm-status” says you must deploy first. I removed the Host, reinstalled the OS on it, deployed it again as new, synced all networks, than deploy once more with HE Deploy, still same issue. Any suggestions? ----- kind regards/met vriendelijke groeten Marko Vrgotic Sr. System Engineer @ System Administration ActiveVideo o: +31 (35) 6774131 m: +31 (65) 5734174 e: m.vrgotic(a)activevideo.com<mailto:m.vrgotic@activevideo.com> w: www.activevideo.com<http://www.activevideo.com> ActiveVideo Networks BV.

How to enable nested virtualization
by miguel.garcia＠toshibagcs.com 02 Mar '21

02 Mar '21

Hi all, We are trying to run virtual box in a vm that is running over ovirt platform. I had followed the instruction to enable nested virtualization on host as described in this document https://ostechnix.com/how-to-enable-nested-virtualization-in-kvm-in-linux/ However I was not able to enable nested virtualization to the vm since nothing is listed from virsh console. Also tryed to edit vm configuration lookig up for "cpu mode" or "copy cpu configuration as host" Also from oVirt admin portal I had enabled host for nested virtualization through Compute > Host > selected Host > edit > Kernel Nested virtualization checked. But the host still returns: $ cat /sys/module/kvm_intel/parameters/nested N

kvm host becomes non operational after breaking a bonding interface
by LS CHENG 02 Mar '21

02 Mar '21

Hi I have created a couple of bonding interfaces in the administrator portal, due to some miss configuration I had to break the bond interfaces, what I observe is that after breaking the bonding interfaces the KVM host becomes non operational and it stays in such state unless I add the bonding interfaces back. Anyone have observed this behaviour? Thanks

2 Node oVirt Cluster
by justin.lamp96＠gmail.com 01 Mar '21

01 Mar '21

Hey there, I tried using oVirt for some time now and like to convert my main Proxmox Cluster (2 Nodes + RPI for Quorum) to oVirt. But I obvioulsy need three servers to do HA. Now I am asking myself: can't I just use the PI as an arbiter node for the Selfhosted-Engine on gluster? I tried running the playbook already, but it's always failing and even if the gluster deployment would go through, it would most likely fail aftwards, right? Before I waste too much energy and time into that, does anyone of you guys use a 2 node cluster? And no I can't add another node (energy + space + money)! Also I know with doing that I'm totally on my own etcetera Thanks!

oVirt4.1 add host error. can i upgrade from 4.1 to 4.4? without updating sequentially 4.1-4.2-4.3-4.4
by grig.4n＠gmail.com 01 Mar '21

01 Mar '21

HI! There is an oVirt 4.1 self-hosted engine cluster of two hosts and a storage connected via iscsi. When trying to add another host, it gives an error: "ERROR otopi.context context._executeMethod:151 Failed to execute stage 'Setup validation': Cannot locate vdsm package, possible cause is incorrect channels". Older hosts on Centos 7.5.1804, last on Centos 7.9.2009. Is it possible to go from 4.1 to 4.4 using the third host as the main one for the transfer?

Cant add vm network with vlan to bonded interface
by murat.celebi＠dbpro.com.tr 01 Mar '21

01 Mar '21

Hello, I am new to ovirt and try to migrate my companies vmware infra to ovirt. The Engine setup went fine without any problems. These are the steps which I am doing and having problems. 1. Prepare the KVM host by installing the RPM's. 2. Add the kvm host to the engine. Everything is working fine at this point. 3. I am creating a new Network for vm usage named VLAN10. And I am tagging the network with vlan id 10. 4. I am bonding two 25Gb/s interface's with balance-xor mode with the name bond1. 5. When I add the network VLAN10 to the bond1 interface I cant see the logical network assigned to the bond. After this step I am not able to delete the bond since I am getting errors when I try to delete the bond. Any help would be greatly appreciated. Thank you

Re: oVirt Engine increase RAM and CPU

I think that I got such case before (4.2) and the only way I managed to update the HE VM was to set the OVF update interval to 1 min and wait for an hour to pass. Best Regards,Strahil Nikolov

Right Glusterfs Config on HA Server
by Marcel d'Heureuse 28 Feb '21

28 Feb '21

Hi Guys or Girls, I have a problem in a productive system. We use three Servers which have a Raid 5 with four Harddrives SATA 8 TB 7200 rpms. The Systems are interconnected for glusterfs with 1 GB/s. The Network Load between all three servers are between 5 and 8 % of the network. The Glusterfs has a separate VLAN which compltete isolated from other networks. Find attached a small drawing. On that server we rum as HA and there are 8 VMs installed. Most of the VMs working well but if there is high load on the system some of the VM can't write the Data in a "good" speed on the disks. The Glusterfs is configured as Replica on the Raid5 disk which is as Jbob in Glusterfs defiend. If i take a look on the iostats i can see that the Harddisk have round 50 open connections some of the glusterfs and a lot of the vms. In side the VMs i can see long iowaiting times from 300 up to 600 ms. With is on case of a Posgresql database very long. Should we configure the Raid5 controller out that the controller only should 4 disks with 8 TB and Glusterfs should connect directly to the /dev/sd[b-e]? What do you think? Will SSD HDD will help on performance but the same config with Raid5 and Jbod could be the bigger problem. Thanks Marcel

oVirt Node install with Foreman VG issue
by simon＠justconnect.ie 28 Feb '21

28 Feb '21

Hi All, I have a server with a RAID1 disk for sda and RAID 5 disk for sdb. Following default install, prior to Cockpit Gluster and Engine wizards there is only a single Volume Group which doesn’t allow me to continue. If I manually configure the install and deselect sdb it gives other issues with multipath but at least I can resolve those. Is there a specific kickstart confuguration that should be used? Kind Regards Shimme

Re: oVirt Node install with Foreman VG issue
by Simon Scott 28 Feb '21

28 Feb '21

Thanks Strahil, Unfortunately changing the filter is done after the initial install. We manually partition sda so that sdb isn’t touched during install. The issues with multipath grabbing sdb are ongoing with a possible manual fix being tested now. Testing has paused at the moment as we have lost gluster on the arbiter node as per https://lists.ovirt.org/archives/list/users@ovirt.org/thread/U64MGWSUCFJRIV… which looks like a full oVirt rebuild again. Any help on that thread would be appreciated. Thanks again Shimme On 28 Feb 2021, at 08:35, Strahil Nikolov <hunter86_bg(a)yahoo.com> wrote: Most probably there is an LVM filter.

3 Node HCI - Local Storage Replica 2+1 After changing the Cluster 'Default Network Provider' from ovirt-provider-ovn to 'No Default Provider' notification (as expected) to reinstall was flagged against each host. Host 3 (Arbiter) was reinstalled but failed to Activate due to Gluster Bricks not starting. No GlusterFS process for the bricks is listed when checking Status of glusterd. Please can someone help to identify the issue and resolution. Attempted further reinstallation of the Host fails. Kind Regards Shimme

oVirt 4.2 cluster upgrade
by Fedele Stabile 26 Feb '21

26 Feb '21

I have a 3 node oVirt 4.2.1 cluster, i'm using a self-hosted engine architecture and storage-engine is on a glusterfs replica 3 of the cluster. The oldest CPU is SandyBridge family (E5-2609) and incidentally I have connectivity problems with IPMI NIC of one node, but Hosted Engine HA is enabled and working. Is it safe to upgrade to the last oVirt 4.4 without a down of vm running on the cluster? May I just click on the button Upgrade that appears on the host page?

25 Feb '21

oVirt 4.4.5 Seventh Release Candidate is now available for testing The oVirt Project is pleased to announce the availability of oVirt 4.4.5 Seventh Release Candidate for testing, as of February 25th, 2021. This update is the fifth in a series of stabilization updates to the 4.4 series. How to prevent hosts entering emergency mode after upgrade from oVirt 4.4.1 Note: Upgrading from 4.4.2 GA or later should not require re-doing these steps, if already performed while upgrading from 4.4.1 to 4.4.2 GA. These are only required to be done once. Due to Bug 1837864 <https://bugzilla.redhat.com/show_bug.cgi?id=1837864> - Host enter emergency mode after upgrading to latest build If you have your root file system on a multipath device on your hosts you should be aware that after upgrading from 4.4.1 to 4.4.5 you may get your host entering emergency mode. In order to prevent this be sure to upgrade oVirt Engine first, then on your hosts: 1. Remove the current lvm filter while still on 4.4.1, or in emergency mode (if rebooted). 2. Reboot. 3. Upgrade to 4.4.5 (redeploy in case of already being on 4.4.5). 4. Run vdsm-tool config-lvm-filter to confirm there is a new filter in place. 5. Only if not using oVirt Node: - run "dracut --force --add multipath” to rebuild initramfs with the correct filter configuration 6. Reboot. 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>.

Starting a defined VM on a different host
by lavi.buchnik＠exlibrisgroup.com 25 Feb '21

25 Feb '21

Hi, I might be missing something here, but I'm looking for the right API way to start a defined VM on a different host. The scenario is this: 1. VM is running under Cluster Affinity Host. and there is a need to cold migrate it to another host on that Affinity. 2. for that I will stop the VM. 3. And now I would like to start the VM on another host, I tried few ways like: vm_service.start( vm=types.Vm( host=types.Host( name='<host name>' ), ) ) But VM keep starting on the current host. Can you please show me the right way to do it. Thanks, Lavi

I am having some issues figuring out how to get a list of VMs and the host that they are running on. I seem to be able to get a reference to the host object, but can't see how to print the name of the host. See the below code snippet: #! /usr/bin/python import ovirtsdk4 as sdk import ovirtsdk4.types as types connection = sdk.Connection( url='https:/<redacted>:443/ovirt-engine/api', username='admin@internal', password='<redacted>', ca_file='ovirt-engine_ca.crt', ) vms_service = connection.system_service().vms_service() vms = vms_service.list() for vm in vms: print("VM.name = " + vm.name) vm_service = vms_service.vm_service(vm.id) #vm = vm_service.get() print(vm.status) if vm.name == 'vmexample': print("HERE") print(vm.host) print(vm.host.name) connection.close() OUTPUT: VM.name = vmexample up HERE <ovirtsdk4.types.Host object at 0x7f5ca250e810> None What am I missing?

Q35: disk type view not consistent in edit vm and new disk pages
by Gianluca Cecchi 24 Feb '21

24 Feb '21

Hello, if I create a VM and select Q35 machine type, still the General --> create image option in edit phase doesn't show sata as an option. Even if I create the VM without disks and then go to edit General --> create, I only see IDE, VirtIO-SCSI and VirtIO. Instead if I click VM name, DIsks --> New, I can select VirtIO-SCSI, VirtIO and SATA After the first disk (SATA in my case) has been created, now if I go and edit VM --> General --> Instance Images + --> Create, I see consistent options. I think GUI experience could be improved. Also because I can reproduce this workflow converging to an error (even if IDE disks are not so common nowadays...): New VM In general I create an IDE disk In System I select in Advanced parameters, Custom Chipset/Firmware Type Q35 (EFI or BIOS based) go ahead At the final OK I get the error: Cannot add Virtual Disk: The disk interface is not supported by the VM OS: Other OS. The result is VM created but without the IDE disk as not supported in Q35 type. Tested in 4.4.4 Gianluca

Cannot add VM. Maximum number of threads per cpu exceeded
by Lavi.Buchnik＠exlibrisgroup.com 24 Feb '21

24 Feb '21

Hi, We have a strange thing, which not clear to us. When provisioning a new VM via REST API, if the number of vCPU for that VM is more than 16, I'm getting this error: Fault reason is "Operation Failed". Fault detail is "[Cannot add VM. Maximum number of threads per cpu exceeded]". HTTP response code is 409. Our version is: Version 4.3.6.6-1.0.9.el7 Note that manual provisioning from the UI do not produce any error when using vCPU > 16. It seems like the issue is related to this setting (from the engine): [root@olvmengine01 ~]# engine-config -g MaxNumOfThreadsPerCpu MaxNumOfThreadsPerCpu: 8 version: 4.1 MaxNumOfThreadsPerCpu: 8 version: 4.2 MaxNumOfThreadsPerCpu: 8 version: 4.3 [root@olvmengine01 ~]# But when trying to set it to another number, I'm always get this error, for example: [root@olvmengine01 ~]# engine-config -s MaxNumOfThreadsPerCpu=10 Please select a version: 1. 4.1 2. 4.2 3. 4.3 3 Cannot set value 10 to key MaxNumOfThreadsPerCpu. Questions: 1. Can you please explain why we getting this error: "Cannot add VM. Maximum number of threads per cpu exceeded"? 2. Is it related to engine-config -g MaxNumOfThreadsPerCpu? 3. Why it is working manually via the UI? 4. if its related to engine-config, why we can't set it to another number? Thanks in advance, Lavi

VM Portal. User can't access the details box
by Nicolás 24 Feb '21

24 Feb '21

Hi, We're running oVirt 4.1.8. We make an intense use of the VM Portal, as our students use it to access and handle their machines. We're currently having an issue with just one of our users. He claims that he created a VM, and when tried to edit its details (clicking on the pencil), a screen stating that the "VM Portal is experiencing some issues" is shown (screenshot added). I granted a UserRole permission on a user I handle, and I don't experience that problem, I can edit the VM with no issues. The user also states that this happens on any VM he creates. I see nothing relevant in the log regarding this issue. Please, any hint how to debug this? Thanks. Nicolás
