re-enabling networkmanager
by fsoyer 23 Oct '18

23 Oct '18

Hi, I have installed a 4.2 cluster on CentOS 7 nodes but I have follow an (old) procedure of mine done with 4.0 : so, I have disabled Network Manager before installing oVirt. The networks created and validated in the engine UI are : ovirmgmt on bond0 (2 slaves) failover mode storagemanager on bond1 (2 slaves), jumbo frames, aggregation mode, serving Gluster. Today, I installed Cockpit on the node to have the nodes consoles. But it say that it cannot manage the network without NM. So my question is : is there any risk to re-enabled NM on the nodes ? Can it broke anything done by the UI ? -- Cordialement, Frank Soyer Mob. 06 72 28 38 53 - Fix. 05 49 50 52 34 Systea IG Administration systèmes, réseaux et bases de données www.systea.net Membre du réseau Les Professionnels du Numérique KoGite Hébergement de proximité www.kogite.fr

PythonSDK 4.2.8 issues updating cdrom iso of a vm.
by Brad Riemann 22 Oct '18

22 Oct '18

Hello, I am currently fighting with attaching an iso to a vm's cdrom. There are two isos in the iso domain (A-Iso-Installer.iso and The-Iso-Installer.iso for our purposes), I can confirm the iso domain is attached to the cluster and everything is green. When attempting to attach the iso to the vm, I can see the pre and post output of the "/ovirt-engine/api/vms/<uuid>/cdroms" request, it shows the file id changing according to what the iso domain has available. However, whenever i attempt to power on the vm, from either the api or through the web interface, I get "Invalid ISO image path". Editing the vm through the web interface reveals that the "Attach CD" dropdown has selected the first iso ("A-Iso-Installer.iso", and I am trying to use the second). I ran a list against the cdrom service, found no issues with the xml that was returned. I confirmed that listing out available isos on the iso domain results in the expected id that I matched in the cdrom service of the vm from the api. If I ch oose the correct iso from the gui and save, the output looks the same as the api listing. Before and After gist: https://gist.github.com/robotman321/909255cbdc36fa62b730a953807f7397 The code im using to set the cdrom is the following: https://gist.github.com/robotman321/35617c96b96b329d5d1476e015aa9898 I did note that when i would run the update api code, it does change SOMETHING as when i go into the web interface the "Attach CD" value has gone back to the top value in the dropdown (the wrong iso). Has anyone seen this before, please tell me it's right in front of me, any help is appreciated. Thank you, Brad

OVN Configuration
by Armond Kuehn 22 Oct '18

22 Oct '18

High I've been trying for a couple months to setup an Ovirt Cluster with OVN/OVS implemented. I can make a network work on my home single server deployment but any time I create a vm on my hyperconverged setup the VM crashes stating it can't connect to the br:ex. (error messages aren't included because lab has 0 external connectivity). I assume this is due to nothing creating the OVN/OVS connections on each host in the manner that my single server does. I know there are ways to manage this such as ManageIQ but I haven't had any luck finding a good guide or walkthrough to get my systems to integrate those products. Does anyone know of where I could find one? Or willing to walk a dummy through it? Armond

Wrong VLAN ID for Management Network
by Sakhi Hadebe 22 Oct '18

22 Oct '18

Hi, Can I just changed the VLAN ID of the ovirtmgmt network in the Admin Portal. IN the OS the network is configured and verified for ovirtmgmt network to have a 21 VLAN ID, but in the Admin Portal, it shows VLAN ID 20, which is configured for the VM network. Can I just changed it in the admin portal? Will the cluster be happy about the changes? -- Regards, Sakhi Hadebe

Problems with quotas
by siovelrm＠gmail.com 21 Oct '18

21 Oct '18

Hi, I need to use Ovirt's quotas system. I have approximately 50 users that use my Ovirt and they can create virtual machines only from templates, in total there are 20 templates. I have assigned a quota for each user, until here there are no problems. The problem is that in order for the user's quota to be used for each template, it must be linked to a specific quota, but only one. The only solution I see would be to have 20 templates for each user so it would be a total of 50X20 templates = 1000 templates and if a new user arrives 20 templates more and so on, which would not be a good solution. I think evidently or that I have not understood well how Ovirt's system of quotas works or maybe my problem can be solved in another way. Please I need your help

I'm not sure where to send a request for including the current Aquantia 107 (10GbaseT nic) driver to be included in the ovirt-node-ng image. I don't see a centos RPM for kmod-redhat-atlantic, apparently there's a scientific linux rpm available for download.

Storage domain has corrupt data
by Chris Burckhard 18 Oct '18

18 Oct '18

We have an iscsi storage domain that has corrupt data. The os boots to the login screen, but does not accept the password, so ovirt cannot connect to it. We are able to boot to a centos live usb and mount the root partitions to see that data, but that doesn't really help since it has iscsi targets. We are seeing errors such as this: ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.GetVGInfoVDSCommand] (org.ovirt.thread.pool-6-thread-21) [3fb88fb0] Command 'GetVGInfoVDSCommand(HostName = 0103ITVH084, GetVGInfoVDSCommandParameters:{runAsync='true', hostId='aaf63dd3-d8b9-4cc2-8ca7-977fbb1ea18a', VGID='sxpvjb-cdco-NyZ9-ReKL-WQdw-WGxG-qNjVCp'})' execution failed: VDSGenericException: VDSErrorException: Failed to GetVGInfoVDS, error = Volume Group does not exist: (u'vg_uuid: sxpvjb-cdco-NyZ9-ReKL-WQdw-WGxG-qNjVCp',), code = 506 Which seems to me that since it is on the live cd, the uuid changed. Is there any way to get the storage domain back online using something like a Centos Live USB? Thank you,

Local disk RAID best practices (HW vs SW RAID)
by Vinícius Ferrão 18 Oct '18

18 Oct '18

Hello, I’m RAIDing the local hypervisor disks. I’m aware that in some scenarios this isn’t even needed. But I would like to know which is the best practice in this scenario: Hardware RAID from a cheap Dell H330 controller, or just leave the controller in HBA mode and make a software RAID during install of the Hypervisor? Thanks, Sent from my iPhone

Is it possible to start a setup of oVirt-Gluster Hyperconverged infrastructure with six nodes ?
by Ravi Linux 18 Oct '18

18 Oct '18

Let's try this question again since my last thread devolved into someone else's question that had nothing to do with this topic. Is there are way to setup a new oVirt-Gluster Hyperconverged infrastructure with six nodes ? All the docs I see start with a 3-node cluster and then adding one node at a time. Is it possible to start with a six node cluster from scratch and use the storage space from all six nodes with Gluster? Six nodes, each contributing 2 TB of disk space. How much shared space will be available ? Thanks in advance for any help on this question. ravi

HCI cleanup of host1 possible?
by Gianluca Cecchi 18 Oct '18

18 Oct '18

Hello, I would like to cleanup a 3 hosts HCI install that didn't complete. If I connect to cockpit of second host it seems like an initial config screen. But if I connect to cockpit of the first host, that I have used in first attempt and I have rebooted in the mean time, it seems to find an engine config and doesn't show choice of install from scratch. On gluster engine volume I have already done clean up. Is there anything I can do on host1 to cleanup its partial config? Thanks, Gianluca

Network configuration for self-hosted engine deployement oVirt node 4.2
by debec.arnaud＠gmail.com 18 Oct '18

18 Oct '18

Dear all, I am going to deploy a self-hosted engine in order to manage 3 servers with 8 network interfaces each. I couldn't find in the documentation when the network shall be configured to perform the self-hosted engine deployment. In others words, what shall be done at the oVirt Node level and what shall managed afterwards via the Engine once the self-hosted engine is performed. Node version: virt-node-ng-installer-ovirt-4.2-2018062610 Storage: SAN via iSCSI I tried this order in my previous tests: 1. Install the oVirt node on every server with DNS configured 2. Configure IP + bond for the administration network (2 interfaces) 3. Configure IP for iSCSI network (4 interfaces) 4. Configure IP + bond for the VM network 5. self-hosted --deploy At this point, oVirt complained by not finding an network interface available for the deployment. Is the bond must be configured afterward via the Engine?

Moving an ISO domain from one storage domain to another
by Mark Steele 18 Oct '18

18 Oct '18

Hello, We are decommissioning a storage array and I would like to move the existing ISO domain to another array. Is there a Move or Migration function for ISO domains? I attempted to create a new ISO domain however that option is not available in the drop down menu. We are running version 3.5.0.1-1.el6 (yes - I know it's old - but it works for us :-) *** *Mark Steele* CIO / VP Technical Operations | TelVue Corporation TelVue - We Share Your Vision 16000 Horizon Way, Suite 100 | Mt.

Backport KVM bug fix for nested KVM in ESXi and Hyper-V
by Gianluca Cecchi 18 Oct '18

18 Oct '18

Hello, I send a dedicated subject message on this topic (second attempt because the first one seems not to be present in ovirt archive..). Also, the reply to my other related message seems not visible inside list archive page for some reason. It seems this nasty problem in nested virt using pc-i440fx-rhel7.X.0 machine type with X >= 3 impacts not only vSphere as main hypervisor for nested KVM, but other hypervisors too (Hyper-V) and other machine types too and could be due to a bug in KVM, so in the kernel, if I understood correctly. According to this link below https://bugs.launchpad.net/qemu/+bug/1636217 and its comment by Roman Kagan in June this year: " This is a KVM bug. It has been fixed in mainstream Linux in commit d391f1207067268261add0485f0f34503539c5b0 Author: Vitaly Kuznetsov <email address hidden> Date: Thu Jan 25 16:37:07 2018 +0100 x86/kvm/vmx: do not use vm-exit instruction length for fast MMIO when running nested I was investigating an issue with seabios >= 1.10 which stopped working for nested KVM on Hyper-V. The problem appears to be in handle_ept_violation() function: when we do fast mmio we need to skip the instruction so we do kvm_skip_emulated_instruction(). This, however, depends on VM_EXIT_INSTRUCTION_LEN field being set correctly in VMCS. However, this is not the case. Intel's manual doesn't mandate VM_EXIT_INSTRUCTION_LEN to be set when EPT MISCONFIG occurs. While on real hardware it was observed to be set, some hypervisors follow the spec and don't set it; we end up advancing IP with some random value. I checked with Microsoft and they confirmed they don't fill VM_EXIT_INSTRUCTION_LEN on EPT MISCONFIG. Fix the issue by doing instruction skip through emulator when running nested. Fixes: 68c3b4d1676d870f0453c31d5a52e7e65c7448ae Suggested-by: Radim Krčmář <email address hidden> Suggested-by: Paolo Bonzini <email address hidden> Signed-off-by: Vitaly Kuznetsov <email address hidden> Acked-by: Michael S. Tsirkin <email address hidden> Signed-off-by: Radim Krčmář <email address hidden> Although the commit mentions Hyper-V as L0 hypervisor, the same problem pertains to ESXi. The commit is included in v4.16. " Is it possible to backport the fix to the kernel provided by plain RHEL/CentOS hosts and/or RHVH/ovirt-ng nodes? Thanks, Gianluca

iSCSI constantly reading from storage (about 8 Mbps) after connecting hosts to storage
by silvio.delval＠pandasecurity.com 17 Oct '18

17 Oct '18

Hello, I recently deployed oVirt in some hosts to evaluate it as one of my main virtualization tool. I like it a lot, but I don't know if this behaviour is normal: I just configured my iSCSI network against a IBM V7000, and from that point on, the host with the role "SPM" continuosly is reading from storage at about 7 or 8 Mbps. I don't know what it i doing, due to no storage domains are still created. How can I know what it is doing ? Regards, Silvio
