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?

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? Thanks! - Marcus ---- %< ---- SNIP ---- %< ----- %< ---- SNIP ---- %< ----- 2019-11-14 14:50:27,155+01 ERROR [org.ovirt.engine.core.vdsbroker.monitoring.FullListAdapter] (EE-ManagedThreadFactory-engineScheduled-Thread-38) [2e46652f] Failed during parsing configuration of VM 133789fc-b329-40b8-bac3-e3ff8c37b1f9 (<domain type='kvm' id='2'> <name>oVirtm</name> <uuid>133789fc-b329-40b8-bac3-e3ff8c37b1f9</uuid> <memory unit='KiB'>4194304</memory> <currentMemory unit='KiB'>4194304</currentMemory> <vcpu placement='static'>2</vcpu> <resource> <partition>/machine</partition> </resource> <os> <type arch='x86_64' machine='pc-i440fx-rhel7.6.0'>hvm</type> <boot dev='hd'/> </os> <features> <acpi/> <apic/> <pae/> </features> <clock offset='utc'> <timer name='kvmclock' present='yes'/> </clock> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>destroy</on_crash> <pm> <suspend-to-mem enabled='no'/> <suspend-to-disk enabled='no'/> </pm> <devices> <emulator>/usr/libexec/qemu-kvm</emulator> <disk type='block' device='disk'> <driver name='qemu' type='raw' cache='none' io='native'/> <source dev='/dev/drbd/by-res/kvm/0'/> <backingStore/> <target dev='vda' bus='virtio'/> <alias name='virtio-disk0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/> </disk> <disk type='file' device='cdrom'> <driver name='qemu' type='raw'/> <source file='/etc/ovirtm/seed.iso'/> <backingStore/> <target dev='hda' bus='ide'/> <readonly/> <alias name='ide0-0-0'/> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </disk> <controller type='usb' index='0' model='none'> <alias name='usb'/> </controller> <controller type='pci' index='0' model='pci-root'> <alias name='pci.0'/> </controller> <controller type='ide' index='0'> <alias name='ide'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x1'/> </controller> <controller type='virtio-serial' index='0'> <alias name='virtio-serial0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/> </controller> <interface type='bridge'> <mac address='52:54:00:75:3c:7d'/> <source bridge='ovirtmgmt'/> <target dev='vnet1'/> <model type='virtio'/> <alias name='net0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> <serial type='pty'> <source path='/dev/pts/4'/> <target type='isa-serial' port='0'> <model name='isa-serial'/> </target> <alias name='serial0'/> </serial> <console type='pty' tty='/dev/pts/4'> <source path='/dev/pts/4'/> <target type='serial' port='0'/> <alias name='serial0'/> </console> <channel type='unix'> <source mode='bind' path='/var/lib/libvirt/qemu/channel/target/domain-2-oVirtm/org.qemu.guest_agent.0'/> <target type='virtio' name='org.qemu.guest_agent.0' state='connected'/> <alias name='channel0'/> <address type='virtio-serial' controller='0' bus='0' port='1'/> </channel> <input type='mouse' bus='ps2'> <alias name='input0'/> </input> <input type='keyboard' bus='ps2'> <alias name='input1'/> </input> <video> <model type='vga' vram='16384' heads='1' primary='yes'/> <alias name='video0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> </video> <memballoon model='none'/> <rng model='virtio'> <backend model='random'>/dev/urandom</backend> <alias name='rng0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/> </rng> </devices> <seclabel type='dynamic' model='selinux' relabel='yes'> <label>system_u:system_r:svirt_t:s0:c624,c838</label> <imagelabel>system_u:object_r:svirt_image_t:s0:c624,c838</imagelabel> </seclabel> <seclabel type='dynamic' model='dac' relabel='yes'> <label>+107:+107</label> <imagelabel>+107:+107</imagelabel> </seclabel> </domain> ), error is: {}: java.lang.NullPointerException 2019-11-14 14:50:27,155+01 ERROR [org.ovirt.engine.core.vdsbroker.monitoring.FullListAdapter] (EE-ManagedThreadFactory-engineScheduled-Thread-38) [2e46652f] Exception:: java.lang.NullPointerException

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

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.

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.

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

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 13 Nov '19

13 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 12 Nov '19

12 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 12 Nov '19

12 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>
