Re: VMs missing following Import of Storage Domain
by Simon Scott
The .ovf files don’t exist on the Primary site for the VMs in question so they are not being replicated.
Question is why aren’t there .ovf files on any of the hosts for those Vms?

gluster heal success but a directory doesn't heal
by Diego Ercolani
Hello list, I have a problem derived from some hangs in ovirt during upgrade procedures, I have a gluster based self hosted engine deploy with "glen" as the gluster based hosted engine volume:
This is the situation I'm facing:
[root@ovirt-node3 master]# gluster volume heal glen info
Brick ovirt-node2.ovirt:/brickhe/glen
/3577c21e-f757-4405-97d1-0f827c9b4e22/master/tasks
Status: Connected
Number of entries: 1
Brick ovirt-node3.ovirt:/brickhe/glen
/3577c21e-f757-4405-97d1-0f827c9b4e22/master/tasks
Status: Connected
Number of entries: 1
Brick ovirt-node4.ovirt:/dati/glen <- arbiter
/3577c21e-f757-4405-97d1-0f827c9b4e22/master/tasks
Status: Connected
Number of entries: 1
so, as manual suggest, I issued a heal operation:
[root@ovirt-node3 master]# gluster volume heal glen
Launching heal operation to perform index self heal on volume glen has been successful
Use heal info commands to check status.
The Heal operation produces no results as the successive heal info report the same from wich I started.
But this is the situation in the log files:
[root@ovirt-node2 ~]# less /var/log/glusterfs/glfsheal-glen.log <- no errors
[root@ovirt-node3 ~]# less /var/log/glusterfs/glfsheal-glen.log <- inside the log I have error entries:
[2022-06-20 07:33:05.891367 +0000] W [MSGID: 114031] [client-rpc-fops_v2.c:2620:client4_0_lookup_cbk] 0-glen-client-2: remote operation failed. [{path=<gfid:44d74dba-19e8-47a3-89e8-f4a6cb37d5ec>}, {gfid=44d74dba-19e8-47a3-89e8-f4a6cb37d5ec}, {errno=2}, {error=No such file or directory}]
[root@ovirt-node4 ~]# less /var/log/glusterfs/glfsheal-glen.log <- same kind of errors
[2022-06-20 07:27:10.486822 +0000] W [MSGID: 114031] [client-rpc-fops_v2.c:2620:client4_0_lookup_cbk] 0-glen-client-1: remote operation failed. [{path=<gfid:b7b1fec5-8246-46eb-afde-ba06f52897d2>}, {gfid=b7b1fec5-8246-46eb-afde-ba06f52897d2}, {errno=2}, {error=No such file or directory}]
On the nodes the glen volume is correctly mounted and:
[root@ovirt-node2 localhost:_glen]# ls -l 3577c21e-f757-4405-97d1-0f827c9b4e22/master/tasks/
[root@ovirt-node3 localhost:_glen]# ls -l 3577c21e-f757-4405-97d1-0f827c9b4e22/master/tasks/
[root@ovirt-node4 localhost:_glen]# ls -l 3577c21e-f757-4405-97d1-0f827c9b4e22/master/tasks/
all return no files
and issuing a ls on the brick source:
[root@ovirt-node2 glen]# ls -l 3577c21e-f757-4405-97d1-0f827c9b4e22/master/tasks/
total 0
[root@ovirt-node3 glen]# ls -l 3577c21e-f757-4405-97d1-0f827c9b4e22/master/tasks/
total 0
drwxr-xr-x. 2 vdsm kvm 156 Jun 9 17:20 ccb6fd19-1b67-42b9-a032-31e12d62ed0e
[root@ovirt-node4 glen]# ls -l 3577c21e-f757-4405-97d1-0f827c9b4e22/master/tasks/
total 0
so it turn out there is some difference between bricks...
Can you please help address this issue?
Thank you

Cannot Log Into Newly Deployed Hosted Engine
by Clint Boggio
I have a fresh installation of a 4.5.1 hosted engine and the admin password I set during the process isn't working. I reset the password for the admin user from a root shell on the HE using the
ovirt-aaa-jdbc-tool utility and still no dice. I found a log file for "keycloak" that I tailed while logging in and discovered that keycloak was denying me. I am not familiar with keycloak at all. It appears as though I enabled keycloak during the deployment.
Just a few quick answers may get me back to where I need to be:
1. How do I log into the web management portal ? Previously it was admin@internal and then the password
2. If keycloak is looking for some kind of directory server outside of the engine I don't have one, if the engine is the keycloak server what are my credentials for the HE portal ?
3. Can I re-run engine-setup and turn Keycloak off so that I have internal based authentication ?
Below is dump of my engine-setup command results:

HCI Deployment oVirt 4.5
by Clint Boggio
Hello oVirt Team
I'm in the process of deploying a three-node oVirt hyperconverged platform and from the cockpit interface of the deployment node I keep running into the same error. The system finishes the gluster deployment phase (sometimes) and then prompts to continue with the hosted engine deployment but then fails immediately complaining about the naming convention of my network interfaces. My network interfaces are 802.3ad bonds configured during the installation process of each node using "bondx" naming convention consistent across all three nodes. Any wisdom or pointers would be appreciated.

Can't start VM because host has insufficient amount of CPU cores
by Ramon Clematide
Hi
I just upgraded my oVirt installation from 4.4.10 to 4.5.1.2. The upgrade went through without any errors and most things seem to work but i have one critical problem now. Somehow it does not evaluate the correct number of CPU available on the hypervisor and blocks the start of a VM (except for the engine). The problem I only have on the hypervisor which has the engine deployed. I have three hypervisors, but only one has the engine installed. This hypervisor is also in a seperate cluster.
After the upgrade, on the hypervisor which has the engine installed, I can't start a VM via the oVirt Manager. I can start the engine via "hosted-engine --vm-start" but if I try to start any other VM it fails with this Error:
https://imgur.com/7lbGb8v
--------------------------------------------------------------------------------------------------------
Operation Canceled
Error while executing action:
Razor:
Cannot run VM. There is no host that satisfies current scheduling constraints. See below for details:
The host venge did not satisfy internal filter CPU because it has an insufficient amount of CPU cores to run the VM.
--------------------------------------------------------------------------------------------------------
I did not change any specs for the VM and even if I reduce the VM to only use 1 core it fails with the error above.
This are the specs of my hypervisor, it has 2 cores with 2 threads:

This is the ovirt version installed

Does someone know how to fix this?

Re: VM hangs after migration
by John
I'm seeing this too on oVirt 4.5.1 using CentOS Stream 8 for the hosts.
The console is blank, no response to ping and I have to power off the VM
and power it back on again to recover it.

Regarding oVirt VM Hosting
by Nishith Vyas
Dear Users,
I've initiated this mail communication for the very first time. Recently,
I've started using *oVirt-Engine* & *oVirt-Node* in my lab as I want to
host a openstack kind of infrastructure hosting environment for my company.
Prior to that, I'd like to get information on the below listed statement.
----------------------------------------------------------------------------------
I've created data domain, iso domain & export domain over the NFS.
Now, my VM is created by loading CentOS 7.9 ISO from "iso domain" & storing
"VM" data on "data domain".
Here, I'm just curious to know about the NFS efficiency to manage VMs
because the OS boots/loads from remote "NFS Data Domain", not from the
local storage (i.e. oVirt-Node)
Which is more efficient? NFS or iSCSI for VM Hosting?
-----------------------------------------------------------------------------------
