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:

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?
-----------------------------------------------------------------------------------

VMs missing following Import of Storage Domain
by simon＠justconnect.ie
Hi All,
I have 2 oVirt 3 node Clusters in 2 Datacenters - effectively 2 independent environements with stretched VLANs for DR purposes.
Each volume is geo replicated to the other datacenter. Each volume is a separate Storage Domain.
In a DR event the geo-replicated volumes/Storage Domains are imported in the other Datacenter and the VMs imported once it's attached.
The issue I am seeing is that some of the VMs are not listed when I click 'VM Import' from the imported Storage Domain. The disks for those missing VMs however, do exist in 'Disk Import' Tab of the imported Storage Domain.
Prior to importing the Storage Domain in Site B, all VM disks were migrated to a single Storage Domain in Site A and geo-replication allowed to sync.
Kind Regards
Simon...

VM hangs after migration
by Giorgio Biacchi
Hi,
I have a fresh Ovirt installation (4.4.10.7-1.el8 engine and oVirt Node
4.4.10) on a Dell VRTX chassis. There are 3 blades, two of them are
identical hardware (PowerEdge M630) and the third is a little newer
(PowerEdge M640). The third has different CPUs, more RAM, and slower
NICs. I also have a bunch of data domains some on the shared PERC
internal storage and others on an external iSCSI storage, all seems
configured correctly and all the hosts are operational.
I can migrate a VM back and forth from the first two blades without any
problem, I can migrate a VM to the third blade but when I migrate a VM
from the third blade to any of the other two the task terminate
successfully, the VM is marked as up on the target host but the VM
hangs, the console is frozen and the VM stops to respond to ping.
I have no clues about why this is happening and I'm looking for
suggestions about how to debug and hopefully fix this issue.
Thanks in advance
