oVirt4.4 HCI single host mortal combat
by Jiří Sléžka 28 May '20

28 May '20

Hi, I am still fighting with oVirt 4.4 installation in HCI single host configuration. Seems to be hard fighter... ;-) It looks like there is no 4.4 HCI single host installation guide so I am using compilation of this sources * https://www.ovirt.org/download/ * https://www.ovirt.org/documentation/gluster-hyperconverged/chap-Single_node… I did * clean minimal install of CentOS 8.1 * setup networks (I am using vlans on bond for internal traffic) dnf update -y dnf install https://resources.ovirt.org/pub/yum-repo/ovirt-release44.rpm dnf install cockpit cockpit-ovirt-dashboard vdsm-gluster ovirt-engine-appliance glusterfs-server gluster-ansible-roles systemctl enable --now cockpit.socket firewall-cmd --add-service=cockpit firewall-cmd --add-service=cockpit --permanent ssh-keygen ssh-copy-id root(a)10.0.4.11 ssh root(a)10.0.4.11 (10.0.4.11 is local address on vlan which I would like use as storage network) I would like to run gluster-ansible-roles from command line but I am not sure how exactly do it right way so I am going the cockpit way and the gluster part works like expected. Next Boss is HE install Round 1, Fight! The hosted engine wizzard ends with missing ca-cert.pem (unfortunately I close the window and cannot find that log anymore). But it looks to me like problem mentioned in https://lists.ovirt.org/archives/list/users@ovirt.org/message/4PUIES2JGAFHJ… I have switched to command line... Round 2, Fight! ovirt-hosted-engine-cleanup ovirt-hosted-engine-setup [ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "The host has been set in non_operational status, deployment errors: code 505: Host ovirt-hci01.stud.slu.cz installation failed.

oVirt not using local GlusterFS bricks
by Randall Wood 28 May '20

28 May '20

I have a three node oVirt 4.3.7 cluster that is using GlusterFS as the underlying storage (each oVirt node is a GlusterFS node). The nodes are named ovirt1, ovirt2, and ovirt3. This has been working wonderfully until last week when ovirt2 crashed (it is *old* hardware; this was not entirely unexpected). Now I have this situation: all three oVirt nodes are acting as if the GlusterFS volumes only exist on ovirt2. The bricks on all three nodes appear to be in sync. I *think* this began happening after I restarted ovirt2 (once hard, and once soft) and then restarted glusterd (and only glusterd) on ovirt1 and ovirt3 after `gluster-eventsapi status` on those two nodes showed inconsistent results (this had been used with success before). How can I make the oVirt nodes read and write from their local bricks?

oVirt 4.4 pending VM changes on HostedEngine VM
by Radoslav Milanov 28 May '20

28 May '20

Hello I'm not sure how but I've got pending changes on the HostedEngine VM on a 3 node 4.4 cluster and those changes are never applied. Is there a way to cancel pending VM changes in general ? Thanks.

Adding extra parameters to qemu-kvm
by Sakari Poussa 28 May '20

28 May '20

Hi, Before I dive in too deeply to vdsm-hook-qemucmdline I'd like to know if it is the correct solution to my needs. I want to add the following (type of) parameters to VM startup -object memory-backend-file,id=mem1,share=on,mem-path=/dev/dax0.0,size=$PMEM_SIZE,align=2M \-device nvdimm,id=nvdimm1,memdev=mem1,label-size=128k \ Is the vdsm-hook-qemucmdline the correct tool? Can I use (add the params) it also from the ansible playbook (via ovirt roles) somehow? Thanks, Sakari

Current Architecture of oVirt and Quality Assurance measures
by Juergen Novak 28 May '20

28 May '20

I am currently evaluating oVirt for the usage in big companies as base system for edge computing applications. I already tried to find a current architecture overview regarding the oVirt modules -- particularly ovirt-node-ng and imgbased. But I did not manage to find any. There is some architecture documentation, but marked as outdated and many links go to 404. So I would ask, if somebody could provide any current architecture overview (no user documentation), particularly of the node module(s). An other question I have, is which quality measures are used in development? * Tools used (for Unit-Tests, Component-Tests, Integration-Tests) * Are there any statistics about test coverage? Any assistance would be appreciated. Best Regards /juergen

oVirt 4.4 gluster single host vm paused due to unknown storage error
by Gianluca Cecchi 28 May '20

28 May '20

Hello, in environment in subject, I downloaded from glance repository the CentOS 8 image CentOS 8 Generic Cloud Image v20200113.3 for x86_64 (5e35c84) and imported as a template. I created a vm based on it (I got the message: "In order to create a VM from a template with a different chipset, device configuration will be changed. This may affect functionality of the guest software. Are you sure you want to proceed?") When running "dnf update", during I/O of packages updates the VM went into pause. VM c8desktop started on Host novirt2.example.net 5/28/201:29:04 PM VM c8desktop has been paused. 5/28/201:41:52 PM VM c8desktop has been paused due to unknown storage error. 5/28/201:41:52 PM VM c8desktop has recovered from paused back to up. 5/28/201:43:50 PM In messages of (nested) host I see: May 28 13:28:06 novirt2 systemd-machined[1497]: New machine qemu-7-c8desktop.

I see in 4.4 Gluster is glusterfs-7.5-1.el8.x86_64 Can this be a problem that only appears in single host as there are indeed no data travellling to the network to sync nodes and sharding feature for some reason is not able to keep pace, when local disk is very fast? In 4.3.9 single host with gluster 6.8-1 my only way to solve was to disable sharding.. and I got final stability see here https://lists.ovirt.org/archives/list/users@ovirt.org/thread/OIN4R63I6ITOQS… Still waiting for Gluster devs comments on logs provided at that time As I already wrote, in my opinion the single host wizard should set sharding off in automatic, because in that environment can make thin provisioned disks unusable. In case of future additions of nodes, the setup can make a check and say the user that he/she should re-enable sharding.... Just my 0.2 eurocent Gianluca

oVirt 4.4 HE on Copy local VM disk to shared storage (NFS) failing
by Anton Gonzalez 28 May '20

28 May '20

Deploy via cockpit fails after copy local VM disk to shared storage, Exit HE maintenance mode, Check engine VM health. The HE VM does not start from shared storage with hosted-engine --vm-status returning down_unexpected. I've also tried with iSCSI, with similar results.

ovirt 4.4.0 - Live merge failure with libvirt error "virDomainBlockCommit() failed"
by Marco Fais 27 May '20

27 May '20

Hi, I have upgraded one of my nodes to oVirt-node 4.4.0 and I am testing the basic functionality in preparation for the full cluster migration. Unfortunately snapshot deletions are not working at the moment; I have a live merge failure most of the times due to a libvirt error -- virDomainBlockCommit() failed I have opened a bug on this as well (https://bugzilla.redhat.com/show_bug.cgi?id=1840414) See the most relevant portion of the vdsm.log here: 2020-05-26 22:43:39,067+0100 ERROR (jsonrpc/1) [virt.vm] (vmId='baaf6be8-dcf4-4f26-b0f1-435287eeed95') Live merge failed (job: 7b96452b-0e60-46c6-9236-6b8a906b0ed8) (vm:5381) Traceback (most recent call last): File "/usr/lib/python3.6/site-packages/vdsm/virt/vm.py", line 5379, in merge bandwidth, flags) File "/usr/lib/python3.6/site-packages/vdsm/virt/virdomain.py", line 101, in f ret = attr(*args, **kwargs) File "/usr/lib/python3.6/site-packages/vdsm/common/libvirtconnection.py", line 131, in wrapper ret = f(*args, **kwargs) File "/usr/lib/python3.6/site-packages/vdsm/common/function.py", line 94, in wrapper return func(inst, *args, **kwargs) File "/usr/lib64/python3.6/site-packages/libvirt.py", line 728, in blockCommit if ret == -1: raise libvirtError ('virDomainBlockCommit() failed', dom=self) libvirt.libvirtError: internal error: qemu block name 'json:{"backing": {"driver": "raw", "file": {"driver": "file", "filename": "/rhev/data-center/mnt/glusterSD/192.168.30.2:_Temp__Storage/246845e5-5546-4f04-948e-66a9532b403f/images/64955343-da61-4b76-9158-8df8363dc5a3/b0558698-bc82-4941-ac52-9fa2385a9f00"}}, "driver": "qcow2", "file": {"driver": "file", "filename": "/rhev/data-center/mnt/glusterSD/192.168.30.2:_Temp__Storage/246845e5-5546-4f04-948e-66a9532b403f/images/64955343-da61-4b76-9158-8df8363dc5a3/be844ebe-10b6-4ac7-89c1-9f8526a52762"}}' doesn't match expected '/rhev/data-center/mnt/glusterSD/192.168.30.2:_Temp__Storage/246845e5-5546-4f04-948e-66a9532b403f/images/64955343-da61-4b76-9158-8df8363dc5a3/be844ebe-10b6-4ac7-89c1-9f8526a52762' 2020-05-26 22:43:39,075+0100 INFO (jsonrpc/1) [api.virt] FINISH merge return={'status': {'code': 52, 'message': 'Merge failed'}} from=::ffff:10.144.138.240,60914, flow_id=dbf9c831-e0cb-4891-a38c-d61136daf029, vmId=baaf6be8-dcf4-4f26-b0f1-435287eeed95 (api:54) 2020-05-26 22:43:39,075+0100 INFO (jsonrpc/1) [jsonrpc.JsonRpcServer] RPC call VM.merge failed (error 52) in 0.18 seconds (__init__:312) This issue was reported also on https://bugzilla.redhat.com/show_bug.cgi?id=1785939; according to the comments the resolution seems to be in libvirt 6.x. However I am not quite sure if / how I can get libvirt 6 in my setup... is there a test image (ideally ovirt-node) I can use? Any suggestions? Unrelated: I had also a problem during the hosted-engine deployment due to the fact the machine is not connected directly to internet and could not complete the dnf update steps (even with the proxy configured it was still failing at a later stage during the engine setup, same problem..). I might open another thread on it... Thanks, Marco

Hello, I'm running oVirt version 4.3.9.4-1.el7. After a failed live storage migration VM got stuck with snapshot. Checking the engine logs I can see that the snapshot removal task is waiting for Merge to complete and vice versa. 2020-05-26 18:34:04,826+02 INFO [org.ovirt.engine.core.bll.snapshots.RemoveSnapshotSingleDiskLiveCommandCallback] (EE-ManagedThreadFactory-engineScheduled-Thread-70) [90f428b0-9c4e-4ac0-8de6-1103fc13da9e] Command 'RemoveSnapshotSingleDiskLive' (id: '60ce36c1-bf74-40a9-9fb0-7fcf7eb95f40') waiting on child command id: 'f7d1de7b-9e87-47ba-9ba0-ee04301ba3b1' type:'Merge' to complete 2020-05-26 18:34:04,827+02 INFO [org.ovirt.engine.core.bll.MergeCommandCallback] (EE-ManagedThreadFactory-engineScheduled-Thread-70) [90f428b0-9c4e-4ac0-8de6-1103fc13da9e] Waiting on merge command to complete (jobId = f694590a-1577-4dce-bf0c-3a8d74adf341) 2020-05-26 18:34:04,845+02 INFO [org.ovirt.engine.core.bll.ConcurrentChildCommandsExecutionCallback] (EE-ManagedThreadFactory-engineScheduled-Thread-70) [90f428b0-9c4e-4ac0-8de6-1103fc13da9e] Command 'RemoveSnapshot' (id: '47c9a847-5b4b-4256-9264-a760acde8275') waiting on child command id: '60ce36c1-bf74-40a9-9fb0-7fcf7eb95f40' type:'RemoveSnapshotSingleDiskLive' to complete 2020-05-26 18:34:14,277+02 INFO [org.ovirt.engine.core.vdsbroker.monitoring.VmJobsMonitoring] (EE-ManagedThreadFactory-engineScheduled-Thread-96) [] VM Job [f694590a-1577-4dce-bf0c-3a8d74adf341]: In progress (no change) I cant see any tasks on sPM via command 2020-05-26 18:34:04,826+02 INFO [org.ovirt.engine.core.bll.snapshots.RemoveSnapshotSingleDiskLiveCommandCallback] (EE-ManagedThreadFactory-engineScheduled-Thread-70) [90f428b0-9c4e-4ac0-8de6-1103fc13da9e] Command 'RemoveSnapshotSingleDiskLive' (id: '60ce36c1-bf74-40a9-9fb0-7fcf7eb95f40') waiting on child command id: 'f7d1de7b-9e87-47ba-9ba0-ee04301ba3b1' type:'Merge' to complete 2020-05-26 18:34:04,827+02 INFO [org.ovirt.engine.core.bll.MergeCommandCallback] (EE-ManagedThreadFactory-engineScheduled-Thread-70) [90f428b0-9c4e-4ac0-8de6-1103fc13da9e] Waiting on merge command to complete (jobId = f694590a-1577-4dce-bf0c-3a8d74adf341) 2020-05-26 18:34:04,845+02 INFO [org.ovirt.engine.core.bll.ConcurrentChildCommandsExecutionCallback] (EE-ManagedThreadFactory-engineScheduled-Thread-70) [90f428b0-9c4e-4ac0-8de6-1103fc13da9e] Command 'RemoveSnapshot' (id: '47c9a847-5b4b-4256-9264-a760acde8275') waiting on child command id: '60ce36c1-bf74-40a9-9fb0-7fcf7eb95f40' type:'RemoveSnapshotSingleDiskLive' to complete 2020-05-26 18:34:14,277+02 INFO [org.ovirt.engine.core.vdsbroker.monitoring.VmJobsMonitoring] (EE-ManagedThreadFactory-engineScheduled-Thread-96) [] VM Job [f694590a-1577-4dce-bf0c-3a8d74adf341]: In progress (no change) I cannot see any runnig tasks on the SPM (vdsm-client Host getAllTasksInfo).

Any Ideas on how I could resolve this? Thank you. Regards, David

oVirt 4.4 and management network requirements
by Gianluca Cecchi 26 May '20

26 May '20

Hello, does oVirt 4.4. support management network distributed between routed networks and not bound to a single one? In some environments I see situations where there are 2 different server farms with networks not necessarily mapped to the same ranges and so it could be useful to let oVirt hosts of the same cluster to be able to communicate but not on the same physical network. Eg vSphere can do it. Thanks in advance, Gianluca

Reconfigure Websocket Proxy
by Anton Louw 26 May '20

26 May '20

Hi Everybody, I tried looking around, but I am stuck. I am trying to reconfigure my Websocket proxy in order to use noVNC. This is after the Hosted Engine name was changed and also after a new SSL cert was added to the Hosted Engine. Most of the articles say that I should run “engine-cleanup”, but after learning the hard way, I would rather not do that again 😊 Any other way anybody knows of? I want to completely remove it and then reinstall it. Thanks Anton Louw Cloud Engineer: Storage and Virtualization ______________________________________ D: 087 805 1572 | M: N/A A: Rutherford Estate, 1 Scott Street, Waverley, Johannesburg anton.louw(a)voxtelecom.co.za www.vox.co.za

How to change IP range of node and hosted engine without break anything ?
by Stéphane Paillet 26 May '20

26 May '20

Hello, I installed an ovirt node and its hosted engine in a lab. After several difficulties to install the engine (I don't know why, I didn't have any problem in the past), I would like to change IPs of both to put them on another vlan. How can I do that without break anything ? My main fear is that the data domain used by the hosted engine use the IP of the node rather than its FQDN. I change other data domains paths, but don't find how to change this one, 'cause I can't modify it, and I can't detach / delete it to recreate another one. I didn't find how to move the engine on another data domain using the node's FQDN in its path. For now, I don't use DNS, I just updated /etc/hosts defs on both servers. If someone could help me, telling me step by step how to change IPs on each element in good order, I would be grateful. Thank you. Cheers, Stephane

ovirt node 4.4 and infiniband
by Giulio Casella 26 May '20

26 May '20

Hi all, I have in production a 4.3.9 setup of ovirt, based on a standalone engine, not HE. I have 3 datacenters (an 3 clusters). One of these clusters is composed of many tenth of HP blades, accessing storage via InfiniBand (used as normal NICs, via ipoib). They're not the state of the art, but I cannot renew the entire hardware. After a setup of ovirt node 4.4 I cannot see ib0 nic. I managed to see it installing CentOS 8, enabling Mellanox repo (https://linux.mellanox.com/public/repo/mlnx_ofed/latest/rhel8.1/mellanox_ml…) and installing package "mlnx-ofed-basic". In Ovirt Node it's not possible, that package require dependencies from CentOS 8 repos, not present in ovirt repo. Is there any chances to have infiniband NICs working in ovirt? TIA, gc

searching in manager
by Jiří Sléžka 25 May '20

25 May '20

Hi, oVirt 4.3.9.4-1.el7 I am trying to search a vms which has storage domain other than RHEV-SSDStorage so I entered this search string in Manager in Compute / Virtual Machines search form. Storage != "RHEV-SSDStorage" but it looks like all vms are listed. When I try... Storage = "RHEV-SSDStorage" ...it works like expected and only right vms are listed. Also combinations seems does not work. Storage = "RHEV-SlowStorage" or Storage = "RHEV-MidStorage" ...returns 0 rows. Should it work? Cheers, Jiri

Hi, I have one vm configured as stateless (useful for example for testing ansible deploying). But now I am in the middle of work and we have planned power outage. If I power down this wm now I will lost my work. It looks like I am unable to create snapshot if vm is in stateless state. Is there any trick how to not loose my stateless state? Is it RFE worth problem? Cheers, Jiri
