Copy the long xml and save it to a file. Then edit and remove the requirement for the mitigations. Then set the following alias: alias virsh='virsh -c qemu:///system?authfile=/etc/ovirt-hosted-engine/virsh_auth.conf' Then : virsh undefine HostedEngine virsh define <file> virsh start HostedEngine Maybe it will work :) Best Regards, Strahil NikolovOn Nov 15, 2019 15:30, Christian Reiss <email(a)christian-reiss.de> wrote: > > On 15/11/2019 13:30, thomas(a)hoberg.net wrote: > > Since there is no guarantee that the oVirt node image and the hosted-engine image are aligned, I'd recommend disabling all mitigations during the host's boot (only got a list of the Intel flags, sorry: Not rich enough for EPYC) and see if that sails through.

In /etc/hosts you first enter the IP then FQDN, and last shortname (aliases). Fix the /etc/hosts file !

Ovirt can use VDO for deduplication and compression, but I think it was related to ZFS.

Gluster Questions
by Christian Reiss 15 Nov '19

15 Nov '19

Hey folks, Running a 3 node HCI cluster (in testing stages) I would love to hear your input. All nodes are exactly identical and have a local storage of 8tb in SSDs made out of a RAID6. Gluster was setup to match this (Raid6, cluster of 256k). There is the option of compression & dedup, coming from ZFS this is a memory hog and kind of insane. What are your thoughts on compression & dedup at this time? The effective size of the compressed drive is suggested 10-fold of the original sizes. Seems a big crazy high; any suggestions here? Thanks for your input! -Chris. -- Christian Reiss - email(a)christian-reiss.de /"\ ASCII Ribbon support(a)alpha-labs.net \ / Campaign X against HTML WEB alpha-labs.net / \ in eMails GPG Retrieval https://gpg.christian-reiss.de GPG ID ABCD43C5, 0x44E29126ABCD43C5 GPG fingerprint = 9549 F537 2596 86BA 733C A4ED 44E2 9126 ABCD 43C5 "It's better to reign in hell than to serve in heaven.", John Milton, Paradise lost.

External VM vdsbroker parsing error
by Marcus van Dam 14 Nov '19

14 Nov '19

Hi, I am running a two node oVirt cluster, based on the "High-Availability oVirt-Cluster with iSCSI-Storage" document published by Linbit. Although a older document, I am happy with the setup. With this setup, I notice a flood of failed VM imports in the engine logs. This setup is based on a separate Qemu VM running the oVirt-Engine. Which seems to be the origin of the error (posted below). Is there anything I can do to either ignore this instance and not fill the logs, or fix the import error?

Do I need to use self hosted engine with a GlusterFs three node setup
by donagh.moran＠oracle.com 14 Nov '19

14 Nov '19

Every piece of documentation I read regarding the setup of Gluster seems to suggest using at least one of the the nodes to host the engine. Is this a requirement of can I use an engine that is deployed on a VM on another server in the same network? Any info would be much appreciated.

Gluster Network Issues....
by rob.downer＠orbitalsystems.co.uk 14 Nov '19

14 Nov '19

I have set up 3 SuperMicro's with Ovirt Node and all pretty sweet. FQDN set up for LAN and also after setup I have enabled a second NIC with FQDN for a Gluster network. The issue is the second ports seem to be unavailable for network access by ping or login.... if you login on root the system says that the ports are available for login on the bash shell after login and node check comes back fine. I have IPMI set up on the systems as well for access. am I missing something ? I realise Gluster should be on a seperate LAN and will put it on a 10BGe network but I'm just testing. I have the lastest stable build. Any help would be appreciated.

Hosted-Engine wizard disappeared after cockpit idle session timeout
by wodel youchi 14 Nov '19

14 Nov '19

Hi, I got this behavior once and I didn't tested again. I started the hosted-engine deployment using cockpit webui, the process went smoothly, the LocalHosttedEngine VM was created, at that time I left the console for sometime. When I get back the cockpit console was closed due to idle session timeout, I reconnect, and the hosted-engine wizard had disappeared and I didn't find a way to get it back, the only choice was to start the process again even if the console was showing that the host was registered with a hosted engine Manager, so I couldn't continue the deployment (the storage phase). I had to stop the LocalHosttedEngine VM, delete it's temporary disk, then restart the deployment again and this time I stick with cockpit webui to get it done. Regards.

engine manager VM not launching
by bepassionatenow＠gmail.com 14 Nov '19

14 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

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.

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).

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

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.

Hi, I did a backup of engine like this # engine-backup --scope=all --mode=backup --file=file_name --log=log_file_name In a newly installed machine try to restore it: # yum install http://resources.ovirt.org/pub/yum-repo/ovirt-release43.rpm # yum update # yum install ovirt-engine # engine-backup --mode=restore --file=file_name --log=log_file_name --provision-db --restore-permissions but get this error: Start of engine-backup with mode 'restore' scope: all archive file: file_name log file: log_file_name Preparing to restore: - Unpacking file 'file_name' Restoring: - Files Provisioning PostgreSQL users/databases: - user 'engine', database 'engine' Restoring: FATAL: Can't connect to database 'ovirt_engine_history'. Please see '/usr/bin/engine-backup --help'. I'm running ovirt Version:4.3.4.3-1.el7 If I run # engine-backup --mode=restore --file=file_name --log=log_file_name --provision-db --no-restore-permissions still the same error Any idea? Many Thanks -- Jose Ferradeira http://www.logicworks.pt

Is this a requirement of can I use an engine that is deployed on a VM on another server in the same network? Any info would be much appreciated. _______________________________________________ moVirt mailing list -- movirt(a)ovirt.org To unsubscribe send an email to movirt-leave(a)ovirt.org Privacy Statement: https://www.ovirt.org/site/privacy-policy/ oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/movirt@ovirt.org/message/7ZA5XNMLS3QQ…
