update to 4.4 fails with "Domain format is different from master storage domain format" (v4.3 cluster with V4 NFS storage domains)
by Sergey Kulikov 30 Sep '20

30 Sep '20

Hello, I'm trying to update our hosted-engine ovirt to version 4.4 from 4.3.10 and everything goes fine until hosted-engine --deploy tries to add new hosted_storage domain, we have NFS storage domains, and it fails with error: [ INFO ] TASK [ovirt.hosted_engine_setup : Activate storage domain] [ ERROR ] ovirtsdk4.Error: Fault reason is "Operation Failed". Fault detail is "[Domain format is different from master storage domain format]". HTTP response code is 400. [ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "Fault reason is \"Operation Failed\". Fault detail is \"[Domain format is different from master storage domain format]\". HTTP response code is 400."} It looks like storage domains in data center should have been upgraded to V5 when DC and cluster compatibility version was updated to 4.3, but looks like it was implemented in ovirt 4.3.3 and this setup was updated from 4.2 to 4.3 before 4.3.3 was released, so I ended up with 4.3 DCs and clusters with V4 storage domain format. Is there any way to convert V4 to V5 (there are running VMs on them) to be able upgrade to 4.4? --

Replica Question
by C Williams 30 Sep '20

30 Sep '20

Hello, We recently received 5 servers. All have about 3 TB of storage. I want to deploy an oVirt HCI using as much of my storage and compute resources as possible. Would oVirt support a "replica 5" HCI (Compute/Gluster) cluster ? I have deployed replica 3s and know about replica 2 + arbiter -- but an arbiter would not be applicable here -- since I have equal storage on all of the planned bricks. Thank You For Your Help !!

Is it possible to change scheduler optimization settings of cluster using ansible or some other automation way
by kushagra2agarwal＠gmail.com 30 Sep '20

30 Sep '20

Do we have any ansible module or any other CLI based approach which can help us to change 'scheduler optimization' settings of cluster in oVIrt. Scheduler optimization settings of cluster can be found under Scheduling Policy tab ( Compute -> Clusters(select the cluster) -> click on edit and than navigate to scheduling policu option) Scheduler Optimization Optimize for Utilization Optimize for Speed

VM without Host stuck in "Rebooting" State
by Raphael Höser 29 Sep '20

29 Sep '20

I have a VM which was send a "Reboot" and "Shutdown" command in short succession (two admins who were not thinking the same way) and now the VM is Stuck in "Rebooting". It has no Host assigned and when trying to turn it of (via Shutdown or Power Off) it gives this error: Sep 29, 2020, 10:27:10 AM Failed to power off VM <vm_name> (Host: <UNKNOWN>, User: admin@internal-authz).

oVirt Change hosts to FQDN
by Jeremey Wise 29 Sep '20

29 Sep '20

I posted that I had wiped out the oVirt-engine.. running cleanup on all three nodes. Done a re-deployment. Then to add nodes back.. though all have entries for eachother in /etc/hosts and ssh works fine via short and long name. I added nodes back into cluster.. but had to do it via IP to get past error. Now, if I go to create a volume via the GUI in gluster I get: Error while executing action Create Gluster Volume: Volume create failed: rc=30800 out=() err=["Host 172_16_100_102 is not in 'Peer in Cluster' state"] Which seems to be related to using IP vs DNS to add gluster volumes https://bugzilla.redhat.com/show_bug.cgi?id=1055928 Question: how do i fix the hosts in cluster being defined by IP vs desired hostname? -- jeremey.wise(a)gmail.com

Source storage domain info in storage live migration
by Gianluca Cecchi 29 Sep '20

29 Sep '20

Hello, having to monitor and check live storage migrations, it seems to me that scrolling through events I can see information about the target storage domain name, but nothing about the source. Is it correct? Can it be added? Which kind of rfe bugzilla should I use in case? Against what? Thanks, Gianluca

Trouble with restoring hosted engine from backup
by Siddharth Patil 29 Sep '20

29 Sep '20

Dear all, I'm trying to restore hosted-engine from backup, but it fails with the following error message: [ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "\"Cluster name cannot be 'Default'. This is a reserved name for the default DataCenter. Please choose\" \" another name for the cluster\""} My DataCenter is called Primary and Cluster is called Default. I have two hosts node01 and node02, with shared storage through NFS. I'm running the restore on node02. I can restore successfully if I change the Cluster name, but then I cannot move node02 to the default cluster, or move node01 to the new cluster, as I cannot shut down the VMs currently running on node01. Please help! Regards, Siddharth

Newbie question on network
by valerio.luccio＠nyu.edu 28 Sep '20

28 Sep '20

I apologize for asking what is probably a very basic question. I installed and created a self-hosted engine using cockpit on a server. I can reach the self-hosted engine from anywhere within my network. I then created a new VM selecting the default ovirtmgmt for the network. The VM does not seem to connect to the network via the bridge. I the used the console to manually configured the network card and I have connectivity between the VM, the engine and the server, but not beyond. What am I doing wrong ? Can someone point to a good documentation page on the subject ? Thanks in advance, Valerio

Cannot change Cluster Compatibility Version after 4.4 upgrade
by paolo＠airaldi.it 28 Sep '20

28 Sep '20

Hi all, we have an oVirt 4.3 with 3 Hosts and 20 VMs. 2 Hosts are Dell PowerEdge R610 with 2 Intel(R) Xeon(R) CPU E5540 processor each (Intel Nehalem IBRS SSBD), while the third is an HP ProLiant ML350p Gen8 with 2 Intel(R) Xeon(R) CPU E5-2620 v2 processor (Intel SandyBridge IBRS SSBD MDS) They all are in the same Cluster. Some of the 20 VMs are Windows (Win 10, Win 2012 and Win 2016) We have upgraded to 4.4.2.6-1.el8 following the instruction https://www.ovirt.org/documentation/upgrade_guide/#SHE_Upgrading_from_4-3. We had some minor issues that have been fixed and now we need to change Cluster Compatibility Version, but it fails complaining about Win10 and Win2016 VMs. In agent.log, for each of them I have: WARN [org.ovirt.engine.core.bll.UpdateVmCommand] (default task-122) [292f1983] Validation of action 'UpdateVm' failed for user admin@internal-authz. Reasons: VAR__ACTION__UPDATE,VAR__TYPE__VM,CPU_TYPE_UNSUPPORTED_FOR_THE_GUEST_OS,$uns upportedCpus opteron_g1, conroe, nehalem, penryn The same messages appear even if the VMs are powered off. We tried to change the Operating System in one VM configuration and if we put Win2012 the VM is no more in the error list when we edit the Cluster, but we're not sure the VMs will restart once Cluster compatibility will be to 4.4 How can we proceed?

Re: oVirt networking.

Hi 1) trunk all the network including management, VM traffic subnets in both ports and tag the management network as native 2) configure the bonds with active/backup with management IP while installing the OS 3) proceed the hosted engine installation in the same management network 4) once hosted engine is up, add all hosts and create vm traffic network with VLAN tags

Re: Recreating ISO storage domain

Actually ISO domain is not necessary. You can moutn it via FUSE to a system and either use the python script ( It was mentioned several times in the mailing list) or the API/UI to upload your ISOs to a data storage domain. I think it is about time to get rid of the deprecated ISO domain.

Even if increasing timeouts would fix the connectivity I suspect the core issue would still remain ... in the best case scenario it could be postponed a bit. Am I correct assuming those 2 DC are located in 2 different physical locations? If so then I would closely check the network itself first (including hardware like routers/switches).

oVirt - Engine - VM Reconstitute
by Jeremey Wise 26 Sep '20

26 Sep '20

As expected... this is a learning curve. My three node cluster.. in an attempt to learn how to do admin work on it, debug it... I have now redeployed the engine and even added second one on a node in cluster. But..... I now realize that my "production vms" are gone. In the past, on a manual build with KVM + Gluster .. when I repaired a damaged cluster I would just then browse to the xml file and import. I think with oVirt, those days are gone. As the PostGres engine knows the links to the disk / thin provision volumes / network / VM definition files. ###### Question: 1) Can someone point me to the manual on how to re-constitute a VM and bring it back into oVirt where all "oVirt-engines" were redeployed. It is only three or four VMs I typically care about (HA cluster and OCP ignition/ Ansible tower VM). 2) How do I make sure these core VMs are able to be reconstituted. Can I create a dedicated volume where the VMs are full provisioned, and the path structure is "human understandable". 3) I know that you can backup the engine. If I had been a smart person, how does one backup and recover from this kind of situation. Does anyone have any guides or good articles on this? Thanks, -- p <jeremey.wise(a)gmail.com>enguinpages

oVirt host "unregistered"
by Jeremey Wise 25 Sep '20

25 Sep '20

Trying to get all the 3 node cluster back fully working... clearing out all the errors. I noted that the HCI wizard.. I thing SHOULD have deployed a hosted engine on the nodes, but this is not the case .. Only thor... the first node in cluster has hosted engine. I tried to redeploy this via the Cockpit wizard to add engine to host.. but I think this may not have been correct repair path. Now node in cluster shows all bricks... green (so it detects after reboot that host is back up and working.. but hosts lists it as "red triangle" with error "unregistered" I also just tried on third node to "edit" -> Host Engine -> and click drop box and choose "deploy" only log in event is "Host medusa configuration was updated by admin@internal-authz. 9/24/208:49:24 PM" but nothing changes.

Node 4.4.1 gluster bricks
by Staniforth, Paul 25 Sep '20

25 Sep '20

Hello, how do you manage a gluster host when upgrading a node? I upgraded/replaced 2 nodes with the new install and can't recreate any gluster bricks. 1 node I wiped it clean and the other I left the 3 gluster brick drives untouched. If I try to create bricks using the UI on the nodes, I get an internal server error. When I try to create a PV from the clean disk, I get device excluded by filter. e.g. pvcreate /dev/sdb Device /dev/sdb excluded by a filter. pvcreate /dev/mapper/SSDSC2KB240G7R_BTYS83100E0S240AGN Device /dev/mapper/SSDSC2KB240G7R_BTYS83100E0S240AGN excluded by a filter.

oVirt 4.4.2 is now generally available
by Lev Veyde 25 Sep '20

25 Sep '20

The oVirt project is excited to announce the general availability of oVirt 4.4.2 , as of September 17th, 2020. This release unleashes an altogether more powerful and flexible open source virtualization solution that encompasses hundreds of individual changes and a wide range of enhancements across the engine, storage, network, user interface, and analytics, as compared to oVirt 4.3. Important notes before you install / upgrade Please note that oVirt 4.4 only supports clusters and data centers with compatibility version 4.2 and above. If clusters or data centers are running with an older compatibility version, you need to upgrade them to at least 4.2 (4.3 is recommended). Please note that in RHEL 8 / CentOS 8 several devices that worked on EL7 are no longer supported. For example, the megaraid_sas driver is removed. If you use Enterprise Linux 8 hosts you can try to provide the necessary drivers for the deprecated hardware using the DUD method (See the users’ mailing list thread on this at https://lists.ovirt.org/archives/list/users@ovirt.org/thread/NDSVUZSESOXEFJ… ) 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>. What’s new in oVirt 4.4.2 Release? This update is the second in a series of stabilization updates to the 4.4 series. This release is available now on x86_64 architecture for: - Red Hat Enterprise Linux 8.2 - CentOS Linux (or similar) 8.2 - CentOS Stream (tech preview) This release supports Hypervisor Hosts on x86_64 and ppc64le architectures for: - Red Hat Enterprise Linux 8.2 - CentOS Linux (or similar) 8.2 - CentOS Stream (tech preview) oVirt Node 4.4 based on CentOS Linux 8.2 (available for x86_64 only) will be released separately due to a blocker issue (Bug 1837864 <https://bugzilla.redhat.com/show_bug.cgi?id=1837864>). oVirt Node and Appliance have been updated, including: - oVirt 4.4.2: http://www.ovirt.org/release/4.4.2/ - Ansible 2.9.13: https://github.com/ansible/ansible/blob/stable-2.9/changelogs/CHANGELOG-v2.… - Glusterfs 7.7: https://docs.gluster.org/en/latest/release-notes/7.7/ See the release notes [1] for installation instructions and a list of new features and bugs fixed. Notes: - oVirt Appliance is already available for CentOS Linux 8 - oVirt Node NG will be available soon for CentOS Linux 8 Additional resources: - Read more about the oVirt 4.4.2 release highlights: http://www.ovirt.org/release/4.4.2/ - Get more oVirt project updates on Twitter: https://twitter.com/ovirt - Check out the latest project news on the oVirt blog: http://www.ovirt.org/blog/ [1] http://www.ovirt.org/release/4.4.2/ [2] http://resources.ovirt.org/pub/ovirt-4.4/iso/ -- Lev Veyde Senior Software Engineer, RHCE | RHCVA | MCITP Red Hat Israel <https://www.redhat.com> lev(a)redhat.com | lveyde(a)redhat.com <https://red.ht/sig> TRIED.

[ANN] oVirt 4.4.3 Second Release Candidate is now available for testing
by Lev Veyde 25 Sep '20

25 Sep '20

oVirt 4.4.3 Second Release Candidate is now available for testing The oVirt Project is pleased to announce the availability of oVirt 4.4.3 Second Release Candidate for testing, as of September 25th, 2020. This update is the third 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 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 4.4.3 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 4.4.3 (redeploy in case of already being on 4.4.3). 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.

export to ova
by Tommaso - Shellrent 25 Sep '20

25 Sep '20

Hi to all. Hi try to ank another time the same question: in our tests ovirt seems to be able to make only one export to ova at time. also on different hosts and datacenter. Someone can explain to us why?? this is for us a big issue, because we use it in a backup script of more than 50 VMs and counting.... We also already opened a bug without any useful response: https://bugzilla.redhat.com/show_bug.cgi?id=1855782 Regards, -- -- Shellrent - Il primo hosting italiano Security First *Tommaso De Marchi* /COO - Chief Operating Officer/ Shellrent Srl Via dell'Edilizia, 19 - 36100 Vicenza Tel. 0444321155 <tel:+390444321155> | Fax 04441492177

oVirt 4.3 HCI ovirtmgmt vlan problem
by wodel youchi 24 Sep '20

24 Sep '20

Hi, I deployed an HCI of three nodes using ovirt 4.3 on a flat network at the beginning, now we need to use VLAN on the management network. I have ovirtmgmt over bond2, this bond will have three vlans : vlan 10 for management, vlan20 for DMZ and vlan30 for DMZ2. On the switch, I did configure the concerned ports to support ; the native vlan (untagged), the vlan10 (tagged), ...etc. Then I activated the tag on the ovirtmgmt network on the web UI, I did lose connexion to the hypervisors and things got weird, I then put my machine on vlan10, I saw that two of my hypervisors had their network configuration modified to use the vlan10, but not the hypervisor where the VM-engine was running. I created the vlan manually on that hypervisor, then I started the VM-Manager, all hosts were recognized. Then I stopped, then started the platforme again. Still the same problem, two hosts are correct with their vlan : bond2.10 created, but the third no vlan. Doing the configuration manually works, but it does not survive reboot, is there a way to force vdsm to accept the new configuration on that faulty host? Regards.

LVM-Thin error node instalation
by Jorge Visentini 24 Sep '20

24 Sep '20

Hello. I'm having trouble installing 4.4.2. The same problem happened in the 4.4.1 media. At the time of post installation, it gives error of LVM Thin Provisioning. I tried to switch from LVM Thin to LVM and the same error happened. In version 4.3 this error does not happen. I was unable to copy the error text, so I am attaching the images. [image: ovirt_installer01.jpg] [image: ovirt_installer02.jpg] Thank you all! -- Att, Jorge Visentini +55 55 98432-9868

ISO Repo
by Jeremey Wise 24 Sep '20

24 Sep '20

I saw notes about oVirt 4.4 may no longer support ISO images... but there are times like now I need to build based on specific ISO images. I tried to do a cycle to create an image file 8GB then do dd if=blah.iso of=/<random disk ID image file name> Created a new vm with this as boot disk and it fails to boot... so.. back to "create volume for iso images" But when I do that I get error New Domain -> "Domain function" =iso Storage type = glusterFs Use Managed Gluster volume -> Select already working gluster file space "thor.penguinpages.local:/iso VFS Type: glusterfs mount options: backup-volfile-servers=odin.penguinpages.local:medusa.penguinpages.local Error: Error while executing action: Cannot add Storage Connection. Performance o_direct option is not enabled for storage domain. Questions: 1) Why did the image and dd of iso to boot disk not work? 2) Any ideas about create of iso mount volume? -- penguinpages

Gluster Name too long
by Jeremey Wise 24 Sep '20

24 Sep '20

Deployment on three node cluster using oVirt HCI wizard. I think this is a bug where it needs to do either a pre-flight name length validation, or increase valid field length. I avoid using /dev/sd# as those can change. And the wizard allows for this change to a more explicit devices Ex: /dev/mapper/Samsung_SSD_850_PRO_512GB_S250NXAGA15787L Error: TASK [gluster.infra/roles/backend_setup : Create a LV thinpool for similar device types] *** task path: /etc/ansible/roles/gluster.infra/roles/backend_setup/tasks/thin_pool_create.yml:239 failed: [thorst.penguinpages.local] (item={'vgname': 'gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L', 'thinpoolname': 'gluster_thinpool_gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L', 'poolmetadatasize': '3G'}) => {"ansible_loop_var": "item", "changed": false, "err": " Full LV name \"gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L/gluster_thinpool_gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L_tdata\" is too long.\n Full LV name \"gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L/gluster_thinpool_gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L_tdata\" is too long.\n Full LV name \"gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L/gluster_thinpool_gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L_tdata\" is too long.\n Full LV name \"gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L/gluster_thinpool_gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L_tdata\" is too long.\n Full LV name \"gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L/gluster_thinpool_gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L_tdata\" is too long.\n Full LV name \"gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L/gluster_thinpool_gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L_tmeta\" is too long.\n Internal error: LV name \"gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L/gluster_thinpool_gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L_tmeta\" length 130 is not supported.\n Internal error: LV name \"gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L/gluster_thinpool_gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L_tdata\" length 130 is not supported.\n Internal error: LV name \"gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L/gluster_thinpool_gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L_tmeta\" length 130 is not supported.\n Internal error: LV name \"gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L/gluster_thinpool_gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L_tdata\" length 130 is not supported.\n", "item": {"poolmetadatasize": "3G", "thinpoolname": "gluster_thinpool_gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L", "vgname": "gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L"}, "msg": "Creating logical volume 'None' failed", "rc": 5} failed: [medusast.penguinpages.local] (item={'vgname': 'gluster_vg_SAMSUNG_SSD_PM851_mSATA_512GB_S1EWNYAF609306', 'thinpoolname': 'gluster_thinpool_gluster_vg_SAMSUNG_SSD_PM851_mSATA_512GB_S1EWNYAF609306', 'poolmetadatasize': '3G'}) => {"ansible_loop_var": "item", "changed": false, "err": " Internal error: LV name \"gluster_vg_SAMSUNG_SSD_PM851_mSATA_512GB_S1EWNYAF609306/gluster_thinpool_gluster_vg_SAMSUNG_SSD_PM851_mSATA_512GB_S1EWNYAF609306\" length 130 is not supported.\n", "item": {"poolmetadatasize": "3G", "thinpoolname": "gluster_thinpool_gluster_vg_SAMSUNG_SSD_PM851_mSATA_512GB_S1EWNYAF609306", "vgname": "gluster_vg_SAMSUNG_SSD_PM851_mSATA_512GB_S1EWNYAF609306"}, "msg": "Creating logical volume 'None' failed", "rc": 5} changed: [odinst.penguinpages.local] => (item={'vgname': 'gluster_vg_Micron_1100_MTFDDAV512TBN_17401F699137', 'thinpoolname': 'gluster_thinpool_gluster_vg_Micron_1100_MTFDDAV512TBN_17401F699137', 'poolmetadatasize': '3G'}) => {"ansible_loop_var": "item", "changed": true, "item": {"poolmetadatasize": "3G", "thinpoolname": "gluster_thinpool_gluster_vg_Micron_1100_MTFDDAV512TBN_17401F699137", "vgname": "gluster_vg_Micron_1100_MTFDDAV512TBN_17401F699137"}, "msg": ""} I will revert back to /dev/sd# for now... but this should be cleaned up.

Host has to be reinstalled
by Jeremey Wise 23 Sep '20

23 Sep '20

Trying to repair / clean up HCI deployment so it is HA and ready for "production". I have gluster now showing three bricks all green Now I just have error on node.. and of course the node which is hosting the ovirt-engine # (as I can not send images to this forum... I will move to a breadcrumb posting) Compute -> Hosts -> "thor" (red exclamation) "Host has to be reinstalled" To fix gluster... i had to reinstall "vdsm-gluster" But what package does this error need to be reviewed / fixed with? -- penguinpages

CLI for HCI setup
by Michael Thomas 23 Sep '20

23 Sep '20

Is there a CLI for setting up a hyperconverged environment with glusterfs? The docs that I've found detail how to do it using the cockpit interface[1], but I'd prefer to use a cli similar to 'hosted-engine --deploy' if it is available. Thanks, --Mike [1]https://www.ovirt.org/documentation/gluster-hyperconverged/chap-Deploying…

info on iSCSI connection setup in oVirt 4.4
by Gianluca Cecchi 23 Sep '20

23 Sep '20

Hello, supposing to have a node that connects to an iSCSI storage domain in oVirt 4.4, is there any particular requirement in the configuration of the network adapter (ifcfg-eno1 file) when I pre-configure the server OS? Eg, do I need to have it managed by NetworkManager in 4.4? Can I instead set NM_CONTROLLED=no for this controller? Thanks in advance, Gianluca

Question on "Memory" column/field in Virtual Machines list/table in ovirt GUI
by KISHOR K 23 Sep '20

23 Sep '20

Hi, Memory field/column for few of VMs in our ovirt (Compute -> Virtual Machines -> Memory column) shows more than 90%. But, when I checked (from free and also other commands) the actual "used" memory by those VMs, it is less than 60%. What I see (from free -h) is that ovirt seems to be considering both "used" + "buff/cache" memory and is reporting the same in GUI. Isn't it the "available" memory that should be considered, because that is the actual memory available and cache memory is something that is adjusted every time? :~> free -h total used free shared buff/cache available Mem: 15Gi 6.8Gi 724Mi 310Mi 8.1Gi 9.2Gi Swap: 0B 0B 0B Can someone help to answer. Thanks ! /Kishore

console breaks with signed SSL certs
by Philip Brown 23 Sep '20

23 Sep '20

Chrome didnt want to talk AT ALL to ovirt with self-signed certs (Because HSTS is enabled) So I installed signed wildcard certs to the engine, and the nodes, following http://187.1.81.65/ovirt-engine/docs/manual/en-US/html/Administration_Guide… and https://cockpit-project.org/guide/172/https.html and chrome is happy now... except that suddenly, consoles refuse to work. and there are no useful errors that I see, other than "Unable to connect to the graphic server" from the remote viewer app. I see someone not too long ago had the exact same problem, in https://www.mail-archive.com/users@ovirt.org/msg58814.html but.. no answer was given to him?

oVirt - KVM QCow2 Import
by Jeremey Wise 22 Sep '20

22 Sep '20

I rebuilt my lab environment. And their are four or five VMs that really would help if I did not have to rebuild. oVirt as I am now finding when it creates infrastructure, sets it out such that I cannot just use older means of placing .qcow2 files in folders and .xml files in other folders.... and they show up on services restarting. How do I import VMs from files? I found this article but implies VM is running: https://www.ovirt.org/develop/release-management/features/virt/KvmToOvirt.h… https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.1/ht… I need a way to import a file. Even if it means temporarily hosting on "KVM on one of the hosts to then bring in once it is up. Thanks -- penguinpages

I would not be wrong but it is not possible to switch from Centos7 to Centos8 .....Can anyone give me some advice?Thank you all!!!

VM stuck in "reboot in progress" ("virtual machine XXX should be running in a host but it isn't.").
by Gilboa Davara 22 Sep '20

22 Sep '20

Hello all (and happy new year), (Note: Also reported as https://bugzilla.redhat.com/show_bug.cgi?id=1880251) Self hosted engine, single node, NFS. Attempted to install CentOS over an existing Fedora VM with one host device (USB printer). Reboot failed, trying to boot from a non-existent CDROM. Tried shutting the VM down, failed. Tried powering off the VM, failed. Dropped cluster to global maintenance, reboot host + engine (was planning to upgrade it anyhow...), VM still stuck. When trying to power off the VM, the following message can be found the in engine.log: 2020-09-18 07:58:51,439+03 INFO [org.ovirt.engine.core.bll.StopVmCommand] (EE-ManagedThreadFactory-engine-Thread-42) [7bc4ac71-f0b2-4af7-b081-100dc99b6123] Running command: StopVmCommand internal: false.

My question is simple: Pending a solution to the bug, can I somehow drop the state of the VM? It's currently holding a sizable disk image and a USB device I need (printer). As it's my private VM cluster, I have no problem dropping the site completely for maintenance. Thanks, Gilboa

Cannot import VM disks from previously detached storage domain
by Strahil Nikolov 22 Sep '20

22 Sep '20

Hello All, I would like to ask how to proceed further. Here is what I have done so far on my ovirt 4.3.10: 1. Set in maintenance and detached my Gluster-based storage domain 2. Did some maintenance on the gluster 3. Reattached and activated my Gluster-based storage domain 4. I have imported my ISOs via the Disk Import tab in UI Next I tried to import the VM Disks , but they are unavailable in the disk tab So I tried to import the VM: 1. First try - import with partial -> failed due to MAC conflict 2. Second try - import with partial , allow MAC reassignment -> failed as VM id exists -> recommends to remove the original VM 3. I tried to detach the VMs disks , so I can delete it - but this is not possible as the Vm already got a snapshot. What is the proper way to import my non-OS disks (data domain is slower but has more space which is more suitable for "data") ? Best Regards, Strahil Nikolov

Hi Everyone, In a test environment I'm trying to deploy a single node self hosted engine 4.4 on CentOS 8 from a 4.3 backup. The actual setup is: - node1 with CentOS7, oVirt 4.3 with a working SH engine. The data domain is a local NFS; - node2 with CentOS8, where we are triyng to deploy the engine starting from the node1 engine backup - host1, with CentOS78, running a couple of VMs (4.3) I'm following the guide: https://www.ovirt.org/documentation/upgrade_guide/#Upgrading_the_Manager_to… Everything seems working fine, the engine on the node1 is in maintenance:global mode and the ovirt-engine service i stopped.

Hello, I’m an Exchange Server VM that’s going down to suspend without possibility of recovery. I need to click on shutdown and them power on. I can’t find anything useful on the logs, except on “dmesg” of the host: [47807.747606] *** Guest State *** [47807.747633] CR0: actual=0x0000000000050032, shadow=0x0000000000050032, gh_mask=fffffffffffffff7 [47807.747671] CR4: actual=0x0000000000002050, shadow=0x0000000000000000, gh_mask=fffffffffffff871 [47807.747721] CR3 = 0x00000000001ad002 [47807.747739] RSP = 0xffffc20904fa3770 RIP = 0x0000000000008000 [47807.747766] RFLAGS=0x00000002 DR7 = 0x0000000000000400 [47807.747792] Sysenter RSP=0000000000000000 CS:RIP=0000:0000000000000000 [47807.747821] CS: sel=0x9100, attr=0x08093, limit=0xffffffff, base=0x000000007ff91000 [47807.747855] DS: sel=0x0000, attr=0x08093, limit=0xffffffff, base=0x0000000000000000 [47807.747889] SS: sel=0x0000, attr=0x08093, limit=0xffffffff, base=0x0000000000000000 [47807.747923] ES: sel=0x0000, attr=0x08093, limit=0xffffffff, base=0x0000000000000000 [47807.747957] FS: sel=0x0000, attr=0x08093, limit=0xffffffff, base=0x0000000000000000 [47807.747991] GS: sel=0x0000, attr=0x08093, limit=0xffffffff, base=0x0000000000000000 [47807.748025] GDTR: limit=0x00000057, base=0xffff80817e7d5fb0 [47807.748059] LDTR: sel=0x0000, attr=0x10000, limit=0x000fffff, base=0x0000000000000000 [47807.748093] IDTR: limit=0x00000000, base=0x0000000000000000 [47807.748128] TR: sel=0x0040, attr=0x0008b, limit=0x00000067, base=0xffff80817e7d4000 [47807.748162] EFER = 0x0000000000000000 PAT = 0x0007010600070106 [47807.748189] DebugCtl = 0x0000000000000000 DebugExceptions = 0x0000000000000000 [47807.748221] Interruptibility = 00000009 ActivityState = 00000000 [47807.748248] *** Host State *** [47807.748263] RIP = 0xffffffffc0c65024 RSP = 0xffff9252bda5fc90 [47807.748290] CS=0010 SS=0018 DS=0000 ES=0000 FS=0000 GS=0000 TR=0040 [47807.748318] FSBase=00007f46d462a700 GSBase=ffff9252ffac0000 TRBase=ffff9252ffac4000 [47807.748351] GDTBase=ffff9252ffacc000 IDTBase=ffffffffff528000 [47807.748377] CR0=0000000080050033 CR3=000000105ac8c000 CR4=00000000001627e0 [47807.748407] Sysenter RSP=0000000000000000 CS:RIP=0010:ffffffff8f196cc0 [47807.748435] EFER = 0x0000000000000d01 PAT = 0x0007050600070106 [47807.748461] *** Control State *** [47807.748478] PinBased=0000003f CPUBased=b6a1edfa SecondaryExec=00000ceb [47807.748507] EntryControls=0000d1ff ExitControls=002fefff [47807.748531] ExceptionBitmap=00060042 PFECmask=00000000 PFECmatch=00000000 [47807.748561] VMEntry: intr_info=00000000 errcode=00000006 ilen=00000000 [47807.748589] VMExit: intr_info=00000000 errcode=00000000 ilen=00000001 [47807.748618] reason=80000021 qualification=0000000000000000 [47807.748645] IDTVectoring: info=00000000 errcode=00000000 [47807.748669] TSC Offset = 0xfffff9b8c8d943b6 [47807.748699] TPR Threshold = 0x00 [47807.748715] EPT pointer = 0x000000105cd5601e [47807.748735] PLE Gap=00000080 Window=00001000 [47807.748755] Virtual processor ID = 0x0003 So something really went crazy. The VM is going down at least two times a day for the last 5 days. At first I thought it would be an hardware issue, so I restarted the VM on other host, and the same thing happened. About the VM it’s configured with 10 CPUs, 48GB of RAM running oVirt 4.3.10 with iSCSI storage to a FreeNAS box, where the VM disks are running; there are a 300GB disc for C:\ and 2TB disk for D:\. Any ideia on how to start troubleshooting it? Thanks,

in ovirt-engine all host show the status at "non-responsive"

hello everyone, I apologize for asking what is probably a very basic question. i have 4 hosts running on the ovirt-engine, but on the last week the alert show all the hosts status has gone to non responsive like the following statement Host 1 became non responsive. It has no power management configured. Please check the host status, manually reboot it, and click "Confirm Host Has Been Rebooted" all the storage, vm, cannot detect on the ovirt-engine, does anyone face this before? and also the alert also show ""Engine's certification has expired at 2020-08-18. Please renew the engine's certification"" is it related to the hosts become non-responsive??? i have already regenerate the ovirt-engine cert from the previous post: https://lists.ovirt.org/archives/list/users@ovirt.org/thread/ZI5WNU6OB6FZMQ… Yours Sincerely, school it
