Moving VMs from 4.3.9 to 4.4.4
by Diggy Mc 28 Dec '20

28 Dec '20

What is the best way to move VMs from current 4.3.9 to a new 4.4.4. environment? The current environment is running oVirt 4.3.9 (started as 4.3.7). There is a single data domain using NFS on a single NAS. The future oVirt 4.4.4 environment will also have a single data domain using NFS on the same NAS as the current environment. What is the best way to move approximately 40 VMs from current 4.3.9 to a new 4.4.4. environment? Are there any caveats or considerations I need to take into account when moving the VMs? Your help, as always, is greatly appreciated.

New to oVirt - HE and Metric Store Question
by Nur Imam Febrianto 28 Dec '20

28 Dec '20

Hi, We’re migrating our 10 physical host with 50 small VM to oVirt from VMware and so happy with its performance. There are two question that we want to ask : 1. Right now we are using one SAN with 4 LUN (each mapped into 1 specific volume) and configure the storage domain for each LUn (1 LUN = 1 Storage Domain). Is this configuration are good ? One more, about Hosted Engine, when we setup the cluster, it provision one storage domain, but the storage domain is not exlusively used by Hosted Engine, we use it too for other VM. Are this OK or it have a side impact ? 2. We’re kind of interested using Metric Store (Need performance metric history over the time), is it possible to deploy the Metric Store using smaller resources ? Our hardware is so small, we cant afford to use that lot of resources for the Metric Store. Thanks before.

power management iLO5

Hi, I've red mail list about IPMI fencing. But clould not find a solution. We have HP gen 10 servers. they have iLO5 and fencing does not work. In redhat there is a solution Issue No iLO5 fencing method available in RHV-manager Power Management via IPMILAN does not work on HPE Gen 10 systems Power Management via iLO4 does not work on HPE Gen 10 systems Resolution The IPMI interface has to be enabled in the security section of a iLO-5 on a HPE Gen 10 system in order to use the fence-agents iLO3, iLO4 or IPMILAN. A user with Login permissions and Operator level access for IPMI should be sufficient for fencing. Root Cause The default settings of iLO-5 on a HPE Gen 10 system have disabled IPMI access to the management controller. The fence agents for iLO-3 onward default to be using IPMI in order to communicate with the management controller. Therefore iLO3, iLO4 as well as IPMILAN fail to connect to a iLO-5 management controller. But, there is no IPMI option in power management. How can i enable power managemenet properly with iLO5 or IPMI? Thanks

4.4.4 hosted engine deployment failure
by Diggy Mc 27 Dec '20

27 Dec '20

While trying to deploy a 4.4.4 hosted engine via the cockpit interface, I received the following error(s): [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Obtain SSO token using username/password credentials] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Wait for the host to be up] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Notify the user about a failure] [ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "Host is not up, please check logs, perhaps also on the engine machine"} ...

I created /var on a separate LV from / (root). I also configured adapter bond per the docs and the same way I did with my 4.3.7 environment. Did I miss a configuration requirement for the OL 8.3 installation? Where can I find more details about the error(s)?

FW: oVirt 4.4 and Active directory
by Latchezar Filtchev 24 Dec '20

Hello , I think I resolved this issue. It is dig response when resolving the domain name! CentOS-7 - bind-utils-9.11.4-16.P2.el7_8.6.x86_64; Windows AD level 2008R2; in my case dig returns answer with ;; ANSWER SECTION: mb118.local. 600 IN A 192.168.1.7 IP address returned is address of DC CentOS-8 - bind-utils-9.11.20-5.el8.x86_64; Same Domain Controller; dig returns answer without ;;ANSWER SECTION e.g. IP address of DC cannot be identified. The solution is to add directive '+nocookie', after '+tcp' in the file /usr/share/ovirt-engine-extension-aaa-ldap/setup/plugins/ovirt-engine-extension-aaa-ldap/ldap/common.py The section starts at line 144: @staticmethod def _resolver(plugin, record, what): rc, stdout, stderr = plugin.execute( args=( ( plugin.command.get('dig'), '+noall', '+answer', '+tcp', '+nocookie', what, record ) ), ) return stdout With this change execution of ovirt-engine-extension-aaa-ldap-setup completes successfully and joins fresh install of oVirt 4.4 to Active Directory. If level of AD is 2016 '+nocookie' change is not needed. Happy holydays to all of you! Stay safe! Thank you!
