engine manager VM not launching
by bepassionatenow＠gmail.com 13 Nov '19

13 Nov '19

Good evening/morning, I can't launch the Engine Manager after the initial install through Cockpit. It initially started fine but I could never login. Cockpit showed that the VM was not set to auto-restart. I don't see how to change that and the button to "run" won't work. Spinning box in the top right corner is causing issues (won't register properly). Any help would be greatly appreciated. Thanks! Daniel

Windows Server 2019 crash dxgkrnl.sys
by gregor 13 Nov '19

13 Nov '19

Hello, during the Installation of Windows Server 2019 after the first reboot the VM crashed and inside the ntbtlog.txt I found that dxgkrnl.sys can not be loaded. Environment: oVirt 4.3.6.7-1.el7 CPU: Intel-Westmere Memory: 4096MB Operation System VM config: Windows 2019 x64 HDD: VirtIO-SCSI VirtIO driver: virtio-win-0.1.171_servers_amd64.vfd Does anybody has an hint how to solve this problem and use Windows Server 2019? Besides: It's possible to install and use Windows Server 2019 in VirtualBox 6.*. We have to install it in the meantime there to have a alternative solution because it took now about two days to find a solution. We tried different settings for VGA and drivers IDE ... and many more. best regards gregor

by Jonathan Mathews 13 Nov '19

13 Nov '19

Good Day I have to change the IP addresses of the oVirt Engine, hosts and storage to a new IP range. Please, can you advise the best way to do this and if there is anything I would need to change in the database? I have also run into an issue where someone has removed the ISO share/data on the storage, so I am unable to remove, activate, detach or even add a new ISO share. Please, can you advise the best wat to resolve this?

DHCP Client in Guest VM does not work on ovirtmgmt
by ccesario＠blueit.com.br 13 Nov '19

13 Nov '19

Hello, Is there any special config to usage dhcp client on Guest VM using ovirtmgmt/ovirtmgmt vnic profile ? Currently I have a VM using the ovirtmgmt/ovirtmgmt NIC profile and this interface is configured as DHCP client, and this does not work when using ovirtmgmt/ovirtmgmt as NIC profile. But if I assign manual IP address from the same range of DHCP server the comunication it works. And If usage other NIC profile in other VLAN with other DHCP server it works. It seems ovirtmgmt/ovirtmgmt profile filter the DHCP protocol. Could someone has idea to allow DHCP protocol works on ovirtmgmt/ovirtmgmt NIC profile? Best regards Carlos

Tesla P4 and /sys/class/mdev_bus/
by Fabrice Bacchella 13 Nov '19

13 Nov '19

I have a Tesla P4 installed on a HPE ProLiant DL360 Gen10 on a CentOS 7.7. The setup was running fine since at least February. I made a successful upgrade from oVirt 4.2 to 4.3 and CentOS 7.6 to CentOS 7.7. I was using in oVirt in a pass-througth setting. I made a minor upgrade a few days ago. And since the VM is unable to see the Tesla P4. I think that the main problem is with mdev. vdsm-client Host hostdevListByCaps | grep mdev return nothing. There is no directory /sys/class/mdev_bus. I tried a full modload: modprobe nvidia_vgpu_vfio nvidia vfio_mdev mdev vfio_iommu_type1 vfio nvidia nvidia-modeset nvidia-drm nvidia-uvm vfio-pci. But it does nothing. Why did my kernel think the P4 is not mdev-compatible any more ? How can I check that ? I think it break when upgrading my kernel from kernel-3.10.0-1062.1.2.el7.x86_64 to kernel-3.10.0-1062.4.1.el7.x86_64. I tried with both the nouveau driver and the nvidia driver.

Re: Do I need to use self hosted engine with a GlusterFs three node setup
by Strahil 13 Nov '19

13 Nov '19

I remember creating my oVirt setup in 2 stages: 1. Using cockpit to deploy the gluster cluster 2. Using cockpit to deploy HCI on the created gluster clustet. If that's not changed you can only deploy the gluster clustet, thrn deploy the engine somewhere else and then connect the engine (add storage domain) to the gluster cluster, which also can be your oVirt compute nodes (making them at the end HyperConverged oVirt Cluster). Of course , that was an year ago - so it could be different.

by Strahil 13 Nov '19

You don't need to host the engine on the gluster cluster. I know people you have hosted the engine on a bare metal (pacemaker cluster) , so feel free to experiment. The only requirement is that tge engine needs to be able to communicate with the hosts (I'm not sure if layer 2 connectivity is necessary).

External networks issue after upgrading to 4.3.6
by ada per 12 Nov '19

12 Nov '19

After upgrading to the latest stable version the external networks lost all functionality. Under providers-->ovn-network-provider the test runs successfully. But when im creating an external provider network, attaching it to a router as a LAN setting up dhcp lease it is not reachable from other VMs in the same network. Hosts and hosted engine can't seem to ping it either. I tried disabling firewalls on both hosted engines, VMs and host and still nothing. When configuring Logical networks or VLANs they work perfectly tje one problem is the external networks. I have another environment running on a previous version of ovirt and it works perfectly there. I think its a bug. Thanks for your help

Re: Migrate VM from oVirt to oVirt
by Strahil 12 Nov '19

12 Nov '19

You will need a storage that will be your 'USB stick' . For example you can attach NFS-based storage domain, migrate the disks of the VM to that storage. Then power off that VM, set the storage to maintenance and then detach it from first oVirt engine. Then you attach and activate that NFS storage in your new oVirt engine. After Activation, there will be an 'Import VMs/templates' tab . Click on it and import the VM in a cluster. Last step is to migrate your VM's disks from that NFS to their permanent storage.

SHE with multipath on multiple iSCSI targets
by Francesco Castellano 12 Nov '19

12 Nov '19

Dear sirs, we're trying to install an SHE oVirt 4.3.6 using an iSCSI SAN that provides us multiple targets (8) over 4 different portals. Following 5.1 of "RHV installation using Cockpit" we set up iscsi and multipath ahead with a 90GB LUN to be used for the engine VM. Unfortunately, even if the node OS sees correctly the LUN, e.g.: # multipath -ll > 36000d31004235a000000000000000018 dm-34 COMPELNT,Compellent Vol > size=90G features='1 queue_if_no_path' hwhandler='0' wp=rw > `-+- policy='service-time 0' prio=1 status=active > |- 16:0:0:3 sdu 65:64 active ready running > |- 24:0:0:3 sdt 65:48 active ready running > |- 17:0:0:3 sds 65:32 active ready running > |- 25:0:0:3 sdv 65:80 active ready running > |- 15:0:0:3 sdx 65:112 active ready running > |- 29:0:0:3 sdw 65:96 active ready running > |- 28:0:0:3 sdy 65:128 active ready running > |- 20:0:0:3 sdz 65:144 active ready running > `- 21:0:0:3 sdaa 65:160 active ready running # lsscsi -ist | grep 36000d31004235a000000000000000018 > [15:0:0:3] disk iqn.2002-03.com.compellent:5000d31004235a43,t,0x0 > /dev/sdx 36000d31004235a000000000000000018 96.6GB > [16:0:0:3] disk iqn.2002-03.com.compellent:5000d31004235a43,t,0x0 > /dev/sdu 36000d31004235a000000000000000018 96.6GB > [17:0:0:3] disk iqn.2002-03.com.compellent:5000d31004235a44,t,0x0 > /dev/sds 36000d31004235a000000000000000018 96.6GB > [20:0:0:3] disk iqn.2002-03.com.compellent:5000d31004235243,t,0x0 > /dev/sdz 36000d31004235a000000000000000018 96.6GB > [21:0:0:3] disk iqn.2002-03.com.compellent:5000d31004235244,t,0x0 > /dev/sdaa 36000d31004235a000000000000000018 96.6GB > [24:0:0:3] disk iqn.2002-03.com.compellent:5000d31004235a48,t,0x0 > /dev/sdt 36000d31004235a000000000000000018 96.6GB > [25:0:0:3] disk iqn.2002-03.com.compellent:5000d31004235a49,t,0x0 > /dev/sdv 36000d31004235a000000000000000018 96.6GB > [28:0:0:3] disk iqn.2002-03.com.compellent:5000d31004235248,t,0x0 > /dev/sdy 36000d31004235a000000000000000018 96.6GB > [29:0:0:3] disk iqn.2002-03.com.compellent:5000d31004235249,t,0x0 > /dev/sdw 36000d31004235a000000000000000018 96.6GB > # iscsiadm -m session | grep -E '[a2]4[3489]' | sort -k 3.8 > tcp: [1] 10.201.204.10:3260,0 iqn.2002-03.com.compellent:5000d31004235a43 > (non-flash) > tcp: [2] 10.201.204.10:3260,0 iqn.2002-03.com.compellent:5000d31004235a43 > (non-flash) > tcp: [3] 10.201.204.10:3260,0 iqn.2002-03.com.compellent:5000d31004235a44 > (non-flash) > tcp: [6] 10.201.204.20:3260,0 iqn.2002-03.com.compellent:5000d31004235243 > (non-flash) > tcp: [7] 10.201.204.20:3260,0 iqn.2002-03.com.compellent:5000d31004235244 > (non-flash) > tcp: [10] 10.201.205.10:3260,0 > iqn.2002-03.com.compellent:5000d31004235a48 (non-flash) > tcp: [11] 10.201.205.10:3260,0 > iqn.2002-03.com.compellent:5000d31004235a49 (non-flash) > tcp: [14] 10.201.205.20:3260,0 > iqn.2002-03.com.compellent:5000d31004235248 (non-flash) > tcp: [15] 10.201.205.20:3260,0 > iqn.2002-03.com.compellent:5000d31004235249 (non-flash) > during the engine deploy neither via cockpit nor with "hosted-engine --deploy" it was able to see any LUN. Having a lot of portals (4) and each having 4 targets (two of which being independents path to the LUN), we chose a portal to discover, it proposed us 4 targets, and we had to choose a target to log in, but in the end, no LUN was proposed. After a few attempts, we found that, if we logged out from any targets (and clean up the open-iscsi database), after the login in an appropriate target, the installer proposed us the LUN, and we successfully deployed the SHE. But unfortunately, such an installation doesn't track effectively all the 8 paths over 8 different targets, but just the one chosen during the installation (this is different, for example, with respect to other LUNs for data domains that we attached afterwards). Thus we miss the HA we aimed to for the engine data domain. I said this, because when I ask for /ovirt-engine/api/storagedomains, whilst a second LUN has 8 children with different targets below storage_domain/${another data domain}/storage/volume_group/logical_units/logical_unit/, for the hosted_storage I just have one. My questions are: a) is there a way to add the other targets/paths consistently (even through the REST interface)? b) is there another installation, or recovery, procedure to get the engine data domain in high availability on our iSCSI topology? Thank you so much for your suggestions, they are really appreciated, Best regards, Francesco Castellano

Quick question regarding FQDN
by Christian Reiss 11 Nov '19

11 Nov '19

Hey folks, for production use quality it is recommended to have backend (storage) and front end seperated. Let' assume: - 85.0.0.0/24 public IP block - 10.100.0.0/24 private IPs for DC internal usage - 10.200.0.0/24 private IPs for storage only LAN and running, as per recommendation 3 nodes: - node01: - fqdn: node01.dc-example.com - fqdn storage: node02.storage.example.com - no public IP - 10.100.0.1 primary IP - 10.200.0.1 storage IP - node02: - fqdn: node02.dc-example.com - fqdn storage: node02.storage.example.com - no public IP - 10.100.0.2 primary IP - 10.200.0.2 storage IP - node03: - fqdn: node03.dc-example.com - fqdn storage: node02.storage.example.com - no public IP - 10.100.0.3 primary IP - 10.200.0.3 storage IP The storage network is its own physical network with 10gig that only connects those three servers. How can I specify which IP to use for storage, which for frontend traffic? I am assuming this as the controller and all admins should be able to reach the nodes via frontend, which is not the storage one. Okay, I am lost. Whats the real solution here? Or is "frontend" no-ip, just VM traffic and "backend" is the 10gig storage "Only" where all the FQDN reside?

I want to configure an web server
by Istiaque Islam 11 Nov '19

11 Nov '19

Hi there, I have installed oVirt on a server and related ISO and Data domains. I can create Virtual Machines and that machine get access to internet to download things. What I want to do now : 1. create an web server using centos and access that webserver from anywhere with internet connection 2. Then I shall configure a domain name for that webserver hosted in oVirt Virtual Machine. My Question : How to configure the virtual machine in oVirt so that when I enter my specified domain name/IP it will hit that particular virtual machine? As it is a virtual machine, it will not get any public IP, so how should i configure the virtual machine set up so that it can be used as an web server. Thanks in advance. -- With Regards, *Mohammed Istiaque Islam* *Contact no *: *+8801745723593* Email : jisan6347(a)gmail.com LinkedIn Profile : Profile_Linkedin_Istiaque <http://www.linkedin.com/in/mohammed-istiaque-islam-59541866>

Of course, this should work. The only point is that once 4.3.6 is released, it's not that easy to install 4.3.5, because yum generally tries to install the latest versions of stuff - and in theory, there might be issues with installing stuff from 4.3.6 repo with a 4.3.5 engine, so if you want an exact replicate of a 4.3.5 engine, you have to check all relevant packages, not just the engine. > > Regards, > Paul S. > ________________________________ > From: Yedidyah Bar David <didi(a)redhat.com> > Sent: 11 November 2019 10:19 > To: Staniforth, Paul <P.Staniforth(a)leedsbeckett.ac.uk> > Cc: wangyu13476969128(a)126.com <wangyu13476969128(a)126.com>; users <users(a)ovirt.org> > Subject: Re: [ovirt-users] Re: After importing the ovirt-engine 4.3.5 backup file into ovirt-engine 4.3.6, will the information of the ovirt-engine 4.3.6 management interface be the same as ovirt-engine 4.3.5? > > On Mon, Nov 11, 2019 at 12:12 PM Staniforth, Paul > <P.Staniforth(a)leedsbeckett.ac.uk> wrote: > > > > I haven't tried it but doesn't engine-setup --offline stop it upgrading minor releases. > > It prevents only the packager component. > > If you already have 4.3.6 installed, which was the original question, > then engine-setup will still update the database schema.

It prevents only the packager component. If you already have 4.3.6 installed, which was the original question, then engine-setup will still update the database schema. And if it didn't, the 4.3.6 engine might fail working correctly with a 3.4.5.5 database.

Supporting larger than 8TiB Lun's iSCSI RHV/oVirt
by Green, Jacob Allen /C 11 Nov '19

11 Nov '19

I have a question regarding the information in the following screenshot. According to https://access.redhat.com/articles/906543 there is an 8TiB limit I assume this is per LUN? Also if I want to go past 8TiB per LUN is there some configuration I need to edit somewhere? And is there a problem with going past 8TiB per LUN? I think it more manageable to simply increase LUN sizes if you have the storage, instead of adding additional LUN’s to your storage domain, however I may not fully understand the problems with increasing LUN sizes. Thank you. [cid:image001.png@01D5948E.D0101740] Jacob.

In order to prevent the ovirt-engine machine from being down, the management interface cannot be used, according to the relevant link: https://ovirt.org/documentation/admin-guide/chap-Backups_and_Migration.html I backed it up using the command: engine-backup --scope=all --mode=backup --file=file_name --log=log_file_name I have prepared another machine as a spare machine. Once the ovirt-engine is down in the production environment, the standby machine can be UP and the standby machine can manage the ovirt-nodes. According to the relevant links: https://ovirt.org/documentation/install-guide/chap-Installing_oVirt.html The ovirt-engine is installed on the standby machine. After I have executed these three commands: 1. yum install http://resources.ovirt.org/pub/yum-repo/ovirt-release43.rpm 2. yum update 3. yum install ovirt-engine I found that the ovirt-engine version of the standby machine is 4.3.6 So my question is: 1. The ovirt-engine version of the standby machine is 4.3.6, and the production environment ovirt-engine version is 4.3.5.5, which command is used on the production environment ovirt-engine machine: engine-backup --scope=all --mode=backup --file=file_name --log=log_file_name Files obtained after using the backup command on the ovirt-engine in the production environment are restored using these two files under the standby computer. Will the information on the ovirt-engine management interface of the standby computer be consistent with the ovirt-engine of the production environment (eg data center, host, virtual machine, etc.)? 2. Can the ovirt-engine of the standby machine be installed with version 4.3.5.5? How do I need to modify the following three commands to get the backup machine to install the version 4.3.5.5? 1. yum install http://resources.ovirt.org/pub/yum-repo/ovirt-release43.rpm 2. yum update 3. yum install ovirt-engine

Long post about gluster issue after 6.5 to 6.6 upgrade and recovery steps
by Strahil Nikolov 10 Nov '19

10 Nov '19

Hello Colleagues, I want to share my experience and especially how I have recovered after a situation where gluster refuses to heal several files of my oVirt Lab. Most probably the situation was caused by the fact that I didn't check if all files were healed before I started the upgrade on the next node , which in a 'replica 2 arbiter1' setup has caused multiple files missing/conflicting and heal fails to happen. Background:1. I have powered off my HostedEngine VM and made a snapshot of the gluster volume2. Started the update , but without screen - I messed it up and decided to revert from the snapshot3. Powered off the volume , restored from snapshot and then started (and again snapshoted the volume)4. Upgrade of the HostedEngine was successfull5. Upgraded the arbiter (ovirt3)6. I forgot to check the heal status on the arbiter and upgraded ovirt1/gluster1 (which maybe was the reason for the issue)7. After gluster1 was healed I saw that some files are left for healing , but expected it will finish till ovirt2/gluster2 is patched8. Sadly my assumption was not right and after the reboot of ovirt2/gluster2 I noticed that some files never heal. Symptoms:2 files per volume never heal (used 'full' mode) even after I 'stat'-ed every file/dir in the volume.Ovirt Dashboard reported multiple errors (50+) that it cannot update the OVF metadata for volume/VM. Here are my notes while I was recovering from the situation. As this is my LAB, I shutdown all VMs (including the HostedEngine) as downtime was not an issue: Heals never complete: # gluster volume heal data_fast4 info Brick gluster1:/gluster_bricks/data_fast4/data_fast4 Status: Connected Number of entries: 0 Brick gluster2:/gluster_bricks/data_fast4/data_fast4 <gfid:d21a6512-eaf6-4859-90cf-eeef2cc0cab8> <gfid:95bc2cd2-8a1e-464e-a384-6b128780d370> Status: Connected Number of entries: 2 Brick ovirt3:/gluster_bricks/data_fast4/data_fast4 <gfid:d21a6512-eaf6-4859-90cf-eeef2cc0cab8> <gfid:95bc2cd2-8a1e-464e-a384-6b128780d370> Status: Connected Number of entries: 2 Mount to get the gfid to path relationship: mount -t glusterfs -o aux-gfid-mount gluster1:/data_fast4 /mnt #

Without downtime , this will not be possible. I hope this long post will help anyone . PS: I have collected some data for some of the files, that I have ommited as this e-mail is very long.

oVirt orb python3/fedora 31 support
by Baptiste Agasse 08 Nov '19

08 Nov '19

Hi all, I was an happy user of oVirt orb on my laptop to do some testing (New features, foreman integration tests , ansible modules/playbooks/roles tests...) and it worked realy well, thanks guys ! Last week I've upgraded my laptop to fedora 31 and I have to uninstall ovirt-orb/lago related stuff to be able upgrade to this fedora version (related to python2 dependencies packages missing on fedora 31). Is there any planned python3/fedora 31 support for ovirt-orb/lago-ovirt/lago ? If not there is any simple replacement solution to spin up a light ovirt env to this kind of tests ? Have a nice day.

Second attempt 😊 From: "Vrgotic, Marko" <M.Vrgotic(a)activevideo.com> Date: Monday, 4 November 2019 at 14:01 To: "users(a)ovirt.org" <users(a)ovirt.org> Subject: oVirt and Netapp question Dear oVirt, Few months ago our production environment oVirt with main Shared storage via NFS Netapp is live. We have been deploying VMs with thin provisioned HDD 40GB based template, CentOS 7. The Netapp NFS v4 storage volume is 7TB in size, also Thin Provisioned. First attached screenshot shows the space allocation of the production volume from Netapp side. Is there anyone in oVirt community who would be able to tell me the meaning of the 5.31 TB Over Provisioned Space? [A screenshot of a cell phone Description automatically generated] Second attached is the info of the production volume from oVirt side: [A screenshot of a social media post Description automatically generated] What I want to understand is the way how is oVirt reading the volume usage and Netapp and where is the difference. Is the Over Allocated Space something that is just logically used/reserved and will be intelligently re-allocated/re-used as the actual Data Space Used grows or am I looking at oVIrt actually hitting Critical Space Action Blocker and will have to resize the volume? If there is anyone from Netapp or with good Netapp experience that is able to help understanding the data above better, thank you in advance? Kindly awaiting your reply. ----- kind regards/met vrindelijke groet Marko Vrgotic ActiveVideo

Users and VM permissions matrix
by Colin Coe 07 Nov '19

07 Nov '19

Hi all I've been tasked with creating a matrix of users/groups and VMs so we can easily see who has access to what (via SPCIE console). Google has given me a couple of hints but I can get it over the line. --- users_service = connection.system_service().users_service() users = users_service.list() for user in users: username = user.user_name.split('@')[0] # Follow the link to the permissions of the user: perms = connection.follow_link(user.permissions) for perm in perms: if perm.vm: print(username) permissions_service = connection.system_service().permissions_service() print(perm.vm.id) --- The problem is with permissions, the output from above is: --- user1 1b645daf-de26-4f33-9e3b-6a12eadd4618 user2 9c79e763-f78d-4bf9-b8ca-20fe197fd80c user3 f9d00b30-8003-41c3-95a1-10e0c452fa63 user4 1bbadf96-ef95-4ece-b5f3-1fa112aa3571 user5 e9085627-324e-48d3-bc04-52ff7798ddd0 --- I can't work out how to get the actual permissions rather that the ID. Any ideas? Thanks

Quick generic Questions
by Christian Reiss 07 Nov '19

07 Nov '19

Hey folks, I am looking at setting up a hyperconverged cluster with 3 nodes (and oVirt 4.3). Before setting up I have some generic questions that I would love to get hints or even an answer on. First off, the Servers are outfittet with 24 (SSD) drives each in a HW-RAID. Due to wear-leveling and speed I am looking at RAID10. So I would end up with one giant sda device. a) Partitioning Using oVirt node installer which will use the full size of /dev/sda is this still the right solution to Hyperconverged given the gluster issue? If I understood it correctly gluster is using empty drives or partitions so a fully utilized drive is of no use here. Does oVirt node installer have a hyperconverged/ gluster mode? b) Storage Location In this 3 node cluster, creating a VM on node01 will the data for node01 always end up in the local node01 server? c) Starting VMs Can a VM be migrated or launched from node03 if the data resides on node01 and node02 (copies 2 with arbiter). d) Efficiency / High IO Load If node01 has high IO Load would additional data be loaded from the other node which has the copy to even the load? I am aware Virtuozzo does this. e) Storage Network dies What would happen with node01, node02 and node03 are operational but only the storage network dies (frontend is still alive as are the nodes). f) external isci/ FreeNAS We have a FreeNAS system with tons of space and fast network connectivity. Can oVirt handle storage import like remote iscsi target and run VMs on the ovirt nodes but store data there? Thank you for your time to clear this up. I have found many approaches out there that either are old (oVirt 3) or even contradict themselves (talk about RAID level...)

All my VMs are using DHCP over ovirtmgmt network. So, yes it should be possible. Are yoiu sure that your hosts' network is in sync ?

CPU Pinning topology
by Fabrice Bacchella 07 Nov '19

07 Nov '19

I'm trying to understand the field "CPU Pinning topology" in the "Ressource Allocation" tab, that looks it needed by High Performance VM. I have this hardware: # lscpu Architecture: x86_64 CPU(s): 48 On-line CPU(s) list: 0-47 Thread(s) per core: 2 Core(s) per socket: 12 Socket(s): 2 NUMA node(s): 2 And I want to run a 22 vCPU vm on it, so no SMT, and 11 vCPU mapped to each socket. The only explanation I found about this field content was here: https://rhv.bradmin.org/ovirt-engine/docs/Virtual_Machine_Management_Guide/… and I can wrap my head around it. Do I need to given explicit mapping for all the 22 vCPU ? And dig in lscpu -e or numactl -H to find how each pCPU is identified ?

Can ovirt-node support multiple network cards ？
by wangyu13476969128＠126.com 07 Nov '19

07 Nov '19

Can ovirt-node support multiple network cards ？ I download ovirt-node-ng-installer-4.3.5-2019073010.el7.iso from ovirt site. And install on a Dell R730 Server. The version of ovirt-engine is 4.3.5.5. I found that the logic network ovirtmgmt can only point to one network card interface. Can ovirt-node support multiple network cards ？ If yes , please tell me the method.

How to pass parameters between VDSM Hooks domxml in single run
by Vrgotic, Marko 06 Nov '19

06 Nov '19

Dear oVIrt, A while ago we discussed on ways to change/update content of parameters of domxml in certain action. As I mentioned before, we have added the VDSMHook 60_nsupdate which removes the DNS record entries when a VM is destroyed: … domxml = hooking.read_domxml() name = domxml.getElementsByTagName('name')[0] name = " ".join(name.nodeValue for name in name.childNodes if name.nodeType == name.TEXT_NODE) nsupdate_commands = """server {server_ip} update delete {vm_name}.example.com a update delete {vm_name}. example.com aaaa update delete {vm_name}. example.com txt send """.format(server_ip="172.16.1.10", vm_name=name) … The goal: However, we did not want to execute remove dns records when VM is only migrated. Since its considered a “destroy” action we took following approach. * In state “before_vm_migrate_source add hook which will write flag “is_migration” to domxml * Once VM is scheduled for migration, this hook should add the flag “is_migration” to domxml * Once 60_nsupdate is triggered, it will check for the flag and if there, skip executing dns record action, but only remove the flag “is_migration” from domxml of the VM … domxml = hooking.read_domxml() migration = domxml.createElement("is_migration") domxml.getElementsByTagName("domain")[0].appendChild(migration) logging.info("domxml_updated {}".format(domxml.toprettyxml())) hooking.write_domxml(domxml) … When executing first time, we observed that flag “ <name>hookiesvm</name> <uuid>fcfa66cb-b251-43a3-8e2b-f33b3024a749</uuid> <metadata xmlns:ns0="http://ovirt.org/vm/tune/1.0" xmlns:ns1="http://ovirt.org/vm/1.0"> <ns0:qos/> <ovirt-vm:vm xmlns:ovirt-vm="http://ovirt.org/vm/1.0"> <ovirt-vm:clusterVersion>4.3</ovirt-vm:clusterVersion> <ovirt-vm:destroy_on_reboot type="bool">False</ovirt-vm:destroy_on_reboot> <ovirt-vm:launchPaused>false</ovirt-vm:launchPaused> <ovirt-vm:memGuaranteedSize type="int">1024</ovirt-vm:memGuaranteedSize> <ovirt-vm:minGuaranteedMemoryMb type="int">1024</ovirt-vm:minGuaranteedMemoryMb> ...skipping... <address bus="0x00" domain="0x0000" function="0x0" slot="0x09" type="pci"/> </rng> </devices> <seclabel model="selinux" relabel="yes" type="dynamic"> <label>system_u:system_r:svirt_t:s0:c169,c575</label> <imagelabel>system_u:object_r:svirt_image_t:s0:c169,c575</imagelabel> </seclabel> <seclabel model="dac" relabel="yes" type="dynamic"> <label>+107:+107</label> <imagelabel>+107:+107</imagelabel> </seclabel> <is_migration/> </domain> is added to domxml, but was present once 60_nsupdate hook was executed. The question: How do we make sure that, when domxml is updated, that the update is visible/usable by following hook, in single run? How to pass these changes between hooks? Kindly awaiting your reply. — — — Met vriendelijke groet / Kind regards, Marko Vrgotic

[feedback needed] oVirt master test
by Sandro Bonazzola 05 Nov '19

Hi, as part of the 4.4 development we'd like to ask for testing current master. In order to ease the test, you can take: oVirt Node: https://resources.ovirt.org/pub/ovirt-master-snapshot/iso/ovirt-node-ng-ins… when this link won't be available anymore due to nightly build rotation you can take the latest from https://resources.ovirt.org/pub/ovirt-master-snapshot/iso/ovirt-node-ng-ins… oVirt appliance: https://resources.ovirt.org/pub/ovirt-master-snapshot/rpm/el8/x86_64/ovirt-… as per oVirt Node, you can take the latest from https://resources.ovirt.org/pub/ovirt-master-snapshot/rpm/el8/x86_64/ if above link doesn't work. The above 2 builds have been tested on a single host nested VM system with 70Gb disk, 8Gb of RAM and 4 cores for the node. Both oVirt Node and oVirt Engine appliance installation succeeded on 80GB NFS external storage with static IP addressing. We have a known issue on booting with more than 1 NIC that will be addressed soon, so please use a single NIC in your tests for now. Looking forward for your feedback, thanks. -- Sandro Bonazzola MANAGER, SOFTWARE ENGINEERING, EMEA R&D RHV Red Hat EMEA <https://www.redhat.com/> sbonazzo(a)redhat.com <https://www.redhat.com/>*Red Hat respects your work life balance.

Hi Dominik, I think I found it - it seems that for some reason my gateway is missing in 'ip route'. Running 'ifdown ovirtmgmt; ifup ovirtmgmt' fixes it, which proves that network scripts read properly the ifcfg-ovirtmgmt file. Do you have any idea where to look for?

Self-Hosted Engine + vxlan + networkd
by pavel＠gremwell.com 04 Nov '19

04 Nov '19

Dear oVirt Community, It appears that oVirt self-hosted engine does not support network configurations based on systemd-networkd? Am I correct? Does oVirt self-hosted engine deployment support VXLAN interface to configure "ovirtmgmt" on top of it? My setup: - three bare-metal servers: two of them are CentOS 7 based, clean installation. the third one is Ubuntu based served as a storage. - all three of them have public Internet connectivity, via basic Ethernet. - in order to emulate internal network, VXLAN was configured between those three. Mainly for testing purposes. - network configuration was done using systemd-networkd, internal communications worked fine. - DNS server was configured on this internal network. worked as direct/reverse resolver. Thus, the main host which I tried to convert to self-hosted engine following https://www.ovirt.org/documentation/self-hosted/chap-Deploying_Self-Hosted_… guide, has the following network interfaces (redacted): - eth0, static IPv4, connected to the Internet; - vxlan0, on top of eth0, has private IPv4, 192.168.200.1; - hosts names resolve via private VXLAN network using 192.168.200.254. I started deployment saying that: Engine FQDN:ovirt-e1.example.com Network Configuration:Static VM IP Address:192.168.200.250/24 Gateway Address:192.168.200.1 DNS Servers:192.168.200.254 hostname of this host on the management network: ovirt-h1.example.com Deployment fails with error "Host ovirt-h1.example.com installation failed. Failed to configure management network on the host." After failure the system (host) does not have "ovirtmgmt" bridge. The same situation was when the host moved from networkd configuration to "network-scripts" (with VXLAN support added). I suspect that the root cause of the problem is that ansible scenarios were not able to create "ovirtmgmt" bridge on top of vxlan0. No switching to VLAN-based management interface... (did not actually tried yet).

oVirt 4.3.6: volume start: engine: failed: Failed to find brick directory /gluster_bricks/engine/engine for volume engine. Reason : No such file or directory
by adrianquintero＠gmail.com 03 Nov '19

While trying to deploy using the WEB UI for single hyperconverged setup I run into this issue (ovirt 4.3.5, ovirt 4.3.6). mount point is "/gluster_bricks/engine" however "/gluster_bricks/engine/engine" is not created. Read a post about gluster 6.1 and having to add /gluster_bricks/engine/.glusterfs/indices manually, I tried it but it did not work, I could not deploy the hosted engine vm.

Re: [ANN] oVirt 4.3.7 First Release Candidate is now available for testing
by Strahil 02 Nov '19

I think I have a theory about ovirt1 , but I have to test it. 1. Ovirt1 has a team device controlled by NetworkManager , but in engine those interfaces are unused 2. I guess that when I recently 'reinstalled' the host from UI, the old teamports' ifcfg-<DEVICENAME> was moved to ifcfg-<DEVICENAME>-1 and the original file was left empty. 3. When the system rebooted, network.service rereads all ifcfg-* files and starts the team0 , but when NetworkManager reads the empty files - he alters the /etc/resolv.conf which leads to out-of-sync status. Still, this is only theory and as ovirt3 has no team device (plain gluster arbiter) - I'm not sure how close is this one.

How to change the CPU of the win10 virtual machine on ovirt-node from 2 cores to 8 cores?
by wangyu13476969128＠126.com 01 Nov '19

01 Nov '19

The version of The ovirt-engine is 4.3.5. I created a win10 virtual machine on ovirt-node, which is allocated 8 cores, and when using the virtual machine I found only 2 cores. I used the command "virsh edit win10" on ovirt-node to prepare to modify the CPU core. I was prompted to enter my username and password. I entered the username and password of the ovirt-engine web interface and ssh log in to the ovirt-node username root and password, but both prompt: Error: failed to connect to the hypervisor Error: authentication failed: authentication failed How can this problem be solved?

I'm not sure, but you can try with replica 1 gluster volume. Later that gluster volume can be changed to replica 2 arbiter 1 or even better replica 3 volume.

Ssh to host and check the status of : sanlock.service supervdsmd.service vdsmd.service ovirt-ha-broker.service ovirt-ha-agent.service For example if sanlock is working, but supervdsmd is not - try to restart it. If it fais, run: systemctl cat supervdsmd.service And execute the commands in sections: ExecStartPre ExecStart And report any issues, then follow the next service in the chain.
