shutdown virtual machine did not display in the list when using virsh list --all and virsh list --state-shutoff
by Kyre 30 Aug '20

Hello, I am using ovirt 4.3.8. I want to use the virsh command to boot the shutdown virtual machine, but when using virsh list --all and virsh list --state-shutoff, the shutdown virtual machine did not display in the list. What is the cause of this, and how can I display the shutdown virtual machine. virsh # list --all Please enter your authentication name: root Please enter your password:  Id    Name                           State ----------------------------------------------------  4     win10E2                  running virsh # list --state-shutoff  Id    Name                           State ----------------------------------------------------

Ovirt Node 4.4.2 Engine Deployment - Notification Settings
by David White 30 Aug '20

30 Aug '20

I finally got oVirt node installed with gluster on a single node. So that's great progress! Once that step was complete... I noticed that the Engine Deployment wizard asks for SMTP settings for where to send notifications. I was kind of surprised that it doesn't allow one to enter any credentials. It looks like this requires an unauthenticated local relay. I don't like that. :) See attached screenshot. Has there been any talk about adding this into the wizard deployment?

Hello, I'm running a home setup with 3 nodes and 2 SATA SSDs per node. As storage I'm running glusterfs and 40GBit/s links.

Missing model_FLAGS on specific host
by Vinícius Ferrão 28 Aug '20

28 Aug '20

Hi, I’ve an strange issue in one of my hosts, it’s missing a lot of CPU flags that oVirt seems to require: [root@c4140 ~]# vdsm-client Host getCapabilities | egrep "cpuFlags|cpuModel" "cpuFlags": "ssse3,mca,ept,pdpe1gb,vmx,clwb,smep,msr,acpi,pge,sse4_2,nopl,cqm_mbm_total,cx16,avx512vl,aperfmperf,xsaves,3dnowprefetch,nonstop_tsc,cmov,mce,intel_pt,avx512f,fpu,pku,tsc,sdbg,erms,pse36,md_clear,apic,sse,pcid,clflushopt,xtopology,pts,monitor,vpid,cpuid,hle,mba,ss,cqm,avx2,ibpb,xgetbv1,flush_l1d,mmx,epb,pti,fxsr,dca,nx,syscall,stibp,mtrr,cx8,sse2,avx,sep,intel_ppin,lm,tm,bts,adx,bmi1,smx,popcnt,pclmulqdq,lahf_lm,mpx,rdseed,cqm_llc,avx512cd,cdp_l3,f16c,invpcid,fsgsbase,cpuid_fault,tm2,smap,dts,pse,xsave,sse4_1,constant_tsc,pat,tsc_deadline_timer,vnmi,avx512dq,dtes64,xsaveopt,ida,pdcm,tpr_shadow,pln,de,x2apic,avx512bw,pae,rdrand,clflush,rdtscp,art,cqm_mbm_local,pebs,ssbd,movbe,pbe,tsc_adjust,vme,ht,est,bmi2,cat_l3,dtherm,ospke,rdt_a,aes,ibrs,rep_good,fma,xtpr,ds_cpl,abm,xsavec,invpcid_single,flexpriority,cqm_occup_llc,pni,rtm,arat,arch_perfmon", "cpuModel": "Intel(R) Xeon(R) Gold 6130 CPU @ 2.10GHz", In a properly working host it have flags like those ones: model_Westmere-IBRS,model_kvm32,model_core2duo,model_Opteron_G1,model_Broadwell,model_qemu64,model_Broadwell-noTSX,model_Nehalem-IBRS,model_Haswell-IBRS,model_pentium2,model_Broadwell-IBRS,model_Haswell-noTSX,model_Haswell,model_Haswell-noTSX-IBRS,model_Conroe,model_pentium,model_n270,model_Nehalem,model_IvyBridge-IBRS,model_kvm64,model_SandyBridge,model_pentium3,model_Broadwell-noTSX-IBRS,model_qemu32,model_486,model_IvyBridge,model_SandyBridge-IBRS,model_Westmere,model_Penryn,model_Opteron_G2,model_coreduo", But in this machine it’s totally missing. I know this model_ flags are an oVirt thing, since they aren’t default on the CPUs. The host machine is a Dell C4140 compute node, the firmware is fully updated, so I’ve done the basic to figure out what’s happening. Thanks,

ovirt 4.4 self-hosted deployment questions
by Michael Thomas 28 Aug '20

28 Aug '20

I have not been able to find answers to a couple of questions in the self-hosted engine documentation[1]. * When installing a new Enterprise Linux host for ovirt, what are the network requirements? Specifically, am I supposed to set up the ovirtmgmt bridge myself on new hosts, or am I supposed to let that be handled by the engine when I add the new host to the engine? * In the 'New Host' dialog on the engine management page, does the Hostname/IP that I enter have to be the host's name on the ovirtmgmt LAN? If so, then it seems to me that I need to configure the ovirtmgmt bridge myself on new hosts. * Does the engine need to be able to route outside of the cluster (eg to the WAN), or is it allowed to restrict the engine's routing to the local cluster? * In the 'New Host' dialog on the engine management page, what is the meaning of 'Choose hosted engine deployment action'? From the way it is phrased, it sounds like this will create a second engine in my cluster, which doesn't make sense. Or does this mean that the new host will be able to run the Engine VM in a HA manner? In my current test deployment I have 3 subnets in my cluster. Network WAN is the WAN. Network CLUSTER is for communication between cluster compute nodes, storage servers, and management servers. Network OVIRT is for ovirt management and VM migration between hosts. My first self-hosted engine host is connected to networks CLUSTER and OVIRT. The engine VM is only connected to network OVIRT through a bridge on the host, but has a gateway that lets it route traffic to network CLUSTER (but not network WAN). Is this an appropriate network setup for ovirt, or should there be no distinction between the CLUSTER and OVIRT networks? --Mike [1]https://www.ovirt.org/documentation/installing_ovirt_as_a_self-hosted_eng…

Hi Everyone, I would like to use Distrbuted Volume type but the volume type is Gray out. I can only use the replicate type. It's normal ? 3 ovirt Servers 4.4.1-2020080418 Can I configure a replicate volume for the engine domain and Distributed for the data domain?

Hi, I have upgraded ovirt to 4.3 and now I have some vm that I can start because of the cluster compatibility version. Those VM where in save state when I updated the cluster compatibility version. Now they are in a down state but if i try to run it I get this message. Cannot run VM. The Custom Compatibility Version of VM vmfpgatest (4.2) is not supported in Data Center compatibility version 4.3. any suggestions? Regards Carl

TroubleshootingoVirt Node deploy FQDN not reachable
by David White 27 Aug '20

27 Aug '20

In a recent thread, Roberto mentioned seeing the error message "FQDN Not Reachable" when trying to deploy oVirt Node 4.4.1, but was able to get past that error when using ovirt-node-ng-installer-4.4.2-2020080612.el8.iso. I experienced the same problems on oVirt Node install 4.4.1, so I tried the latest release of 4.4.2. When that failed, I went back and installed from the exact same image as Roberto said worked on the 4.4.2 branch: ovirt-node-ng-installer-4.4.2-2020080612.el8.iso Unfortunately, that's still not working for me - so that tells me I'm probably doing something wrong. Given the following facts: [root@dev1-centos ~]# hostname dev1-centos.office.barredowlweb.com [root@dev1-centos ~]# host dev1-centos.office.barredowlweb.com dev1-centos.office.barredowlweb.com has address 192.168.2.96 I am trying to install oVirt using the Hyperconverged Gluster Wizard for a Single Node. In the "Host1" box, I enter the full hostname: dev1-centos.office.barredowlweb.com And that's when I get the FQDN error message. Am I missing something here? Sent with ProtonMail Secure Email.

Is the Hosted Engine setup finished + Can't connect vdsm storage

Hi, We have 6 node oVirt setup with Compatibility version 4.3 running on CentOS 7.6.1810 Recently We have found out some very interesting log entries on a few of our nodes. /var/log/ovirt-hosted-engine-ha/broker.log: MainThread::INFO::2020-08-27 12:51:50,279::storage_backends::345::ovirt_hosted_engine_ha.lib.storage_backends::(connect) Connecting the storage MainThread::INFO::2020-08-27 12:51:50,280::storage_server::349::ovirt_hosted_engine_ha.lib.storage_server.StorageServer::(connect_storage_server) Connecting storage server MainThread::warning::2020-08-27 12:51:50,284::storage_broker::97::ovirt_hosted_engine_ha.broker.storage_broker.StorageBroker::(__init__) Can't connect vdsm storage: 'NoneType' object has no attribute 'startswith' /var/log/messages Aug 27 12:52:11 ildeco25 vdsm[6909]: ERROR failed to retrieve Hosted Engine HA score '[Errno 2] No such file or directory'Is the Hosted Engine setup finished? We have inherited that setup from the previous team but I'm fairly certain the the Hosted Engine setup is finished. Also, this line is not present on all hosts.
