oVirt 4.4.3 Sixth Release Candidate is now available for testing
The oVirt Project is pleased to announce the availability of oVirt 4.4.3
Sixth Release Candidate for testing, as of October 22th, 2020.
This update is the third in a series of stabilization updates to the 4.4
How to prevent
All networking configs have been checked and correct.
I just looked at the gluster volume and noticed the Mount Option
‘logbsize=256k’ on two nodes and is not on the third node.
Status of volume: pltfm_data01

Virt settings are those:
[root@ovirt1 slow]# cat /var/lib/glusterd/groups/virt
I might be wrong, but I think that the SAN LUN is used as a PV and then each
disk is a LV from the Host Perspective.
Of course , I could be wrong and someone can correct me. All my oVirt
experience is based on HCI (Gluster + oVirt).

thanks for the info - I learned it the hard way (trial & error) and so far it
Do we have an entry about that topic in the documentation ?

I agree with Alex.
Also, most of the kernel tunables proposed in that thread are also available in
the tuned profiles provided by the redhat-storage-server source rpm available
Usually the alignment of XFS ontop the HW raid
I'm trying to preform an upgrade from 4.3 to 4.4 using the hosted engine option
Unfortunately, when it goes to create the hosted engine disk images I get the
[Cannot move Virtual Disk. The operation is not supported
Finally got back around to this. Solved it by creating a subdirectory under
the actual share and mounting that.
Thanks for the help,

Hi Ales, the problem was resolved by starting NetworkManager.
Previously our workflow had always been to disable firewalld, and
Is it the case that newer ovirt 4.3.x uses NetworkManager to enumerate
What resolved the situation: create a single ethernet NIC (no
Someone can tell you more about technical details with SPM and other
cool stuff which does the clustering but basically all disks are
usable on all nodes simultaneously. So different VM's from node1 and
node2 can use the same storage domain. This also enables live
migration and storage
I just upgraded one of my test oVirt setups to latest.
Post reboot, the machine lost network and hosted engine didn't start.
When I connected to the machine, I noticed all the
/etc/sysconfig/network-scripts/ifcfg-* files disappeared. No idea why /
how. (Possibly I did something wrong
I just noticed there were many typos, old keyboard!
let me fix
Thanks for the reply.
So LVM is used in ovirt, I guess only a host can use the LVM mount point
because it is not a clustered LVM correct? In other words and for example if I
have a LVM with this setup in ovirt and 2 KVM
Thanks for the reply.

I'm going to do some tests and will let you know

Here is the post link:
For example, a window machine runs to slow, usually the disk is allways in 100%
The group virt settings is this?:
performance.quick-read=off performance.read-ahead=off performance.io-cache=off
performance.low-prio-threads=32 network.remote-dio=enable features.shard=on
Thanks. Added my bug report as a possible duplicate.

We use oVirt with FC SAN in our environment. Basically you just make
LUN in SAN and attach that to the Storage domain. oVirt uses LVM on
top of that storage for VM's and this happens automatically. All nodes
where the LUN is seen can use the storage. You can also add multiple
LUNs in one
I see that a 4.3.11 version is available for downstream RHV but not for

Are there only security fixes inside or also bug fixes (like the few lines
one related to export as OVA)?

I am having hard time understanding Storage Domains in oVirt. All our storage
are SAN and I wonder how can we manage SAN LUN in oVirt to create a storage
