update host to 4.4: manual ovn config necessary?
by Gianluca Cecchi
Hello,
I have updated an external engine from 4.3 to 4.4 and the OVN configuration
seems to have been retained:
[root@ovmgr1 ovirt-engine]# ovn-nbctl show

(ovirt-ovn172-4ac7ba24-aad5-432d-b1d2-672eaeea7d63)
[root@ovmgr1 ovirt-engine]#
Then I updated one of the 3 Linux hosts (not node ng) through remove from
web admin gui, install from scratch of CentOS 8.2 OS, configure repos and
then add new host (with the same name) in engine and I was able to connect
to storage (iSCSI) and start VMs in general on the host.
Coming to OVN part it seems it has not been configured on the upgraded host.
Is it expected?
Eg on engine I only see chassis for the 2 hosts still in 4.3:
[root@ovmgr1 ovirt-engine]# ovn-sbctl show
Chassis "b8872ab5-4606-4a79-b77d-9d956a18d349"
hostname: "ov301.mydomain"
Encap geneve
ip: "10.4.192.34"
options: {csum="true"}
Port_Binding "174b69f8-00ed-4e25-96fc-7db11ea8a8b9"
Port_Binding "66359e79-56c4-47e0-8196-2241706329f6"
Chassis "ddecf0da-4708-4f93-958b-6af365a5eeca"
hostname: "ov300.mydomain"
Encap geneve
ip: "10.4.192.33"
options: {csum="true"}
Port_Binding "ccbd6188-78eb-437b-9df9-9929e272974b"
[root@ovmgr1 ovirt-engine]#
What to do to add the upgraded 4.4 host? Can they live together for the OVN
part?
Thanks,
Gianluca

when configuring multi path logical network selection area is empty, hence not able to configure multipathing
by dhanaraj.ramesh＠yahoo.com
Hi team,
I have 4 node cluster where in each node I configured 2 dedicated 10 gig NIC with dedicated subnet each ( NIC 1 = 10.10.10.0/24, NIC 2 = 10.10.20.0/24 ) and on the array side I configured 2 targets with 10.10.10.0 /24 & another 2 target with 10.10.20.0/24 subnet. without any errors I could check in all four paths and able to mount iscsi luns in all 4 nodes. However when i try to configure mutipathing at Data center level I could see all the paths but not the logical network, it stays empty although I configured logical network label for both NICs with dedicated names as ISCSI1 & ISCI2. these logical names visible and green at the host network level, no errors, they are just L2 IP config
Am I missing something here? what else I should do to enable multiplathing

problems installing standard Linux as nodes in 4.4
by Gianluca Cecchi
Hello,
due to missing megaraid_sas kernel module in RH EL 8 and CentOS 8, I'm
deploying a new oVirt host using CentOS 8 and elrepo kernel driver and not
ovirt node ng.
Based on installation guide:
- install CentOS 8.2 ("Server" chosen as base environment)
- yum install https://resources.ovirt.org/pub/yum-repo/ovirt-release44.rpm
- yum install cockpit-ovirt-dashboard
- yum update
- reboot
Try to add host from engine web admin gui, I get:
Host ov200 installation failed. Failed to execute Ansible host-deploy role:
Failed to execute call to start playbook. . Please check logs for more
details: /var/log/ovirt-engine/ansible-runner-service.log.
Inside the log file above on engine:
2020-10-08 11:58:43,389 - runner_service.controllers.hosts - DEBUG -
Request received, content-type :None
2020-10-08 11:58:43,390 - runner_service.controllers.hosts - INFO -

Do I have to enable any module or pre-install anything else before adding
it?
BTW: on host
[root@ov200 ~]# rpm -q ansible
ansible-2.9.13-2.el8.noarch
[root@ov200 ~]#

Left over hibernation disks that we can't delete
by james＠deanimaconsulting.com
After putting the VMs in our environment into hibernation, one of the VMs that came out of hibernation still has the metadata and memory dumb hanging around as 2 disks with status ok. They are not attached to any VM but we are unable to delete them. The VM in question came out of the hibernation without any issues.
If they are no longer required how can we tidy them up?
Thanks, James

adminstration portal wont complete load, looping
by Philip Brown
I have an odd situation:
When I go to
https://ovengine/ovirt-engine/webadmin/?locale=en_US
after authentication passes...
it shows the top banner of
oVirt OPEN VIRTUALIZATION MANAGER
and the
Loading ...
in the center. but never gets past that. Any suggestions on how I could investigate and fix this?
background:
I recently updated certs to be signed wildcard certs, but this broke consoles somehow.
So I restored the original certs, and restarted things... but got stuck with this.
Interestingly, the VM portal loads fine. But not the admin portal.

reinstall 4.3 host from 4.4 engine
by Gianluca Cecchi
Hello,
supposing I'm with an already upgraded 4.4.2 engine and in my environment I
still have some 4.3.10 hosts based on CentOS Linux 7.x (or 4.3.10 ng
nodes), is it supported to reinstall such host in case of any modification
in configuration?
Or will the engine try to install them in a "4.4" way?
Thanks in advance,

Manual VM Migration fails
by Anton Louw
Hello Everybody,
I am having a strange issue. When I try and manually migrate a VM from one host to another, I get an error stating:
"Migration failed (VM: VM1, Source: node6.example.com, Destination: node3.example.com)"
I have tried with a few different machines, and it pops up with the same error. I have attached the VDSM logs of both source and destination nodes. The time frame is 16:01
I see the below in that time frame, but not quite sure what I need to change:
