Ovirt Engine -- Connection Refused to all hosts
by Nick Polites 18 May '21

18 May '21

Hi All, I am not sure if my original post is being reviewed before posting but trying again in case it failed to send. I tried logging in this morning to oVrit and see that all of my hosts are unresponsive. I am seeing a connection refused error in the engine logs. I am able to SSH and ping the host from the engine. Any help would be appreciated. 2021-05-15 15:19:21,041Z ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.GetCapabilitiesAsyncVDSCommand] (EE-ManagedThreadFactory-engineScheduled-Thread-65) [] Command 'GetCapabilitiesAsyn cVDSCommand(HostName = hlkvm03, VdsIdAndVdsVDSCommandParametersBase:{hostId='2186eca7-4d9d-482f-b1b7-b63ac46b96aa', vds='Host[hlkvm03,2186eca7-4d9d-482f-b1b7 -b63ac46b96aa]'})' execution failed: java.net.ConnectException: Connection refused ~

Migrating VMs with templates from 4.2.8 to new 4.4.6 instance
by Pavel Strzinek 17 May '21

17 May '21

Hello, I am having hard time migrating vms based on templates from existing 4.2.8 instance to newly installed 4.4.6 HCI with different storage. When I export VMs and corresponding templates to export NFS storage, detach it from source DC and attach the export storage to a new oVirt environment, the import of templates is failing with error "Failed to import Template XXX to Data Center YYY, Cluster ZZZ". I cannot find anything more specific about the error in logs. Am I missing something? Exporting to OVA and importing back does work, but I want to make use of template thin provisioning.

Create Brick from Engine host view
by Harry O 16 May '21

16 May '21

When I try to create a single disk brick via host view "storage devices" on engine, I get the following error. Error while executing action Create Brick: Internal Engine Error Failed to create brick lalaf on host hej1.5ervers.lan of cluster Clu1. I want the brick to be single disk no raid, no cache. Is there a way to create it via CLI? Do I need to pull some logs?

Power management on Dell PowerEdge R320 and R520
by Pavel Strzinek 14 May '21

14 May '21

Hello, I am having trouble configuring fencing on these two servers with iDrac7 module from freshly installed oVirt 4.4.6. I tried drac5, drac7 and ipmilan modules and neither passes the test. I used ipmilan with option "lanplus=1", as noted in previous threads about idrac usage with oVirt/RHEV, but with no success. Also, I am successfully using ipmilan fencing from older oVirt 4.2 on several SuperMicro server nodes. This is the error message in engine.log: 2021-05-14 09:28:41,185+02 ERROR [org.ovirt.engine.core.bll.pm.FenceProxyLocator] (default task-6) [12faf352-da4a-4b24-9ab9-af54559cecd1] Can not run fence action on host 'onode1', no suitable proxy host was found. I can successfully query the idrac module with ipmitool from command line on the node, using the same credentials.

Moving interfaces for switch maintenance
by David White 12 May '21

12 May '21

So I have two switches. All 3 of my HCI oVirt servers are connected to both switches. 1 switch serves the ovirtmgmt network (internal, gluster communication and everything else on that subnet) The other switch serves the "main" front-end network (Private). It turns out that my datacenter plugged the switches into the wrong power supplies, and now needs to move them. My switches have single PSUs, so when we move them, the network will go down. Obviously, I'm just going to move 1 switch at a time. What I'm wondering, though, is there's an "easy" way to force all the traffic for both networks out one of the single interfaces, so that I don't experience any more downtime during this switch maintenance. Should I assign another temporary IP address on each of the interfaces for each server that is in the same subnet as the switch we're going to take down? Sent with ProtonMail Secure Email.

Issue upgrading from 4.3 (Centos 7) to 4.4 (Centos 8)
by ling＠aliko.com 12 May '21

12 May '21

Hello, I have been trying to upgrade my self-hosted engine from 4.3 to 4.4 but running into issue while performing hosted-engine deploy. Old hypervisor hosts are all running Centos 8 and old ovirt-engine is also running Centos 7. I created a brand new baremental node running Centos 8, Kernel 4.18.0-240.15.1.el8_3.x86_64 and the following engine versions: ovirt-hosted-engine-setup-2.4.9-1.el8.noarch ovirt-hosted-engine-ha-2.4.6-1.el8.noarch ovirt-engine-appliance-4.4-20210323171213.1.el8.x86_64 python3-ovirt-engine-sdk4-4.4.10-1.el8.x86_64 I have many VLANs in my environment. But on this host, I only have these network devices set up (eth0 is the main network, eth1 for storage): # nmcli con NAME UUID TYPE DEVICE ovirtmgmt 02f64861-d992-4e56-8cec-da1906bac09f bridge ovirtmgmt System eth1 bd9e565f-bdc3-4e43-bbd3-5875b9d7fed7 ethernet eth1 virbr0 78e6875d-70f6-4c89-89dd-180dbb9250b1 bridge virbr0 eth0 743b0e26-aae7-44b8-9215-3754a537e90b ethernet eth0 vnet0 bcfead6d-c5b6-4428-9f89-41589735be02 tun vnet0 When I run hosted-engine --deploy --restore-from-file=backup_050321.bck, it hangs after showing: [ INFO ] TASK [ovirt.ovirt.engine_setup : Copy yum configuration file] [ INFO ] changed: [localhost -> ovirt.safari.apple.com] [ INFO ] TASK [ovirt.ovirt.engine_setup : Set 'best' to false] [ INFO ] changed: [localhost -> ovirt.safari.apple.com] [ INFO ] TASK [ovirt.ovirt.engine_setup : Update all packages] virsh shows the VM is in paused state: # virsh list Id Name State ---------------------------------- 1 HostedEngineLocal paused I was able to ssh onto the VM until that point. Do I need to set up all the network connection for all the VLANs before running the deploy script? And how about engine storage domain? I have a new NFS mount ready but it did not ask me about which storage domain to use. Will it ask in later stage? Thanks.
