Removing Direct Mapped LUNs
by Ryan Chewning
Hi List,
We need to add and remove directly mapped LUNs to multiple VMs in our
Non-Production environment. The environment is backed by an iSCSI SAN. In
testing when removing a directly mapped LUN it doesn't remove the
underlying multipath and devices. Several questions.
1) Is this the expected behavior?
2) Are we supposed to go to each KVM host and manually remove the
underlying multipath devices?
3) Is there a technical reason that oVirt doesn't do this as part of the
steps to removing the storage?
This is something that was handled by the manager in the previous
virtualization that we used, Oracle's Xen based Oracle VM.
Thanks!

upgrading to 4.4.6 with Rocky Linux 8
by Jason Keltz
Hi..
I'm looking to migrate soon from CentOS 7.9 with oVirt 4.3.10 to Rocky
Linux 8.4 with oVirt 4.4.6. I'm working on my kickstart of my
standalone engine in a VM at the moment.
So far, with minimal experience with Rocky Linux, after my kickstart, I
was able to run "engine-setup", follow all the defaults and then access
my "new" engine via web. I have to explore the actual procedure for
installing on my current engine host, and restoring my data.
When oVirt team releases new releases, I'm just wondering if you test
going from the last previous release (4.3.10 in this case) to each
latest release? I know that the documentation says we always need to
make sure we update to each individaul major release, but I'm just
wondering if this is something that oVirt team tests with each release?
I'm very concerned for potential of failed upgrade, and the potential
headaches that it could cause.
I see the 4.4.6 was released in time with RHEL 8.3. I'd like to use
Rocky Linux 8.4 because I believe RHEL has re-enabled mptsas (though I
know still unsupported) from 8.4+ which will make things easier.
Any additional suggestions or caveats of the upgrade?
Thanks for any feedback,
Jason.

upgrading gluster brick os from CentOS7 to 8
by Jiří Sléžka
Hello,
I'm in progress of moving my oVirt HCI cluster to production. It was a
bit complicated process because I had two new servers to install oVirt
from scratch in the lab and three old servers with standalone kvm
hypervisors in production. One of them (installed with CentOS7) was good
enough to join HCI cluster. All three old kvm servers had production vms
running on them.
New cluster was installed with CentOS8 and oVirt4.4, I started with
single node, then expanded it to two hosts with one another which acts
as arbiter (just for stability in lab envirnment).
After some testing and tuning I moved this two node cluster (without
arbiter node) to my server housing. Then I prepared gluster brick on
that one old server which I want reuse and join it to gluster storage so
now it is replica 3 - two nodes are CentOS8 based and acts as oVirt
hosts, one is CentOS7 and acts also as standalone kvm hypervisor.
Then I migrated all vms from standalone kvm hypervisors to oVirt, then
switched off two oldest hosts.
Now I would like to reinstall CentOS7 node to oVirt host. My plan is to
keep gluster brick fs and backup configuration and restore it after
reinstall to CentOS8 as mentioned in
https://mjanja.ch/2018/08/migrate-glusterfs-to-a-new-operating-system/.
I want to speed up gluster healing. Does it make sense?
Now the questin: Brick fs was created on CentOS7 and don't have new xfs
features FINOBT,SPARSE_INODES,REFLINK. Could it be problem? Will be
better to recreate fs in CentOS8 and then do full heal? I am afraid that
it will take a long time and make big load to production hosts.
TL;DR: Does gluster/oVirt4.4 make use of FINOBT,SPARSE_INODES,REFLINK
xfs features?
btw. oVirt is great product and HCI looks really functional and usable
(with 10GE network and SSDsof course). Big thanks to developers and
community!
Cheers,
Jiri

It seems I have the same problem with my 4.4.5.
Any info if it is fixed in the latest 4.4.6? It seems no update inside the

CentOS 8 to Stream conversion
by Gary Pedretty
I have moved all my hosts from CentOS 8 to Stream, but the hosted engine is still Centos 8. Is it safe to use the same conversion of the hosted-engine from 8 to Stream while in global maintenance mode?
IE:
dnf swap centos-{linux,stream}-repos
dnf distro-sync
Thanks
Gary

Windows 10 Guest with nvidia Tesla P40 vGpu Bluescreens when I enable nested virtualization
by domw＠live.ca
Hi all,
I have this issue when I go to create a VM, I want to run WSL2 but when I install it or windows defender application guard the computer bluescreens.
So I am using CentOS 8 stream host connected to a VirtIO cluster the hardware is 2 Nvidia Tesla P40 graphics cards installed on a poweredge R480. My windows 10 20H2 Image would bluescreen after the nvidia drivers are installed. I did some testing and discovered after installing a clean ISO windows 10 20H2 that it worked fine even after installing the drivers for the vGPU but the master image does have WSL2 installed out of the box so I installed it on my Vanilla image and it would bluescreen. I imagine this is due to the nested virtualization and the installation of some hyper-v service maybe it is trying to initialize some hardware acceleration. Has anyone had this issue I really need WSL and would love to use version 2.
Tesla Version I have tried is 450.12 and the latest 460.32

migrate hosted engine
by Harry O
Hi,
I get the following when trying to migrate my HostedEngine VM to a new node in the cluster, I just did node reinstall via HostedEngine and rebuild of the gluster array on that node, bacause its a replacement for a crashed dead old node.
ID: 120
Migration failed due to an Error: Failed to connect to remote libvirt URI qemu+tls://hej3.5ervers.lan/system: Cannot read CA certificate '/etc/pki/CA/cacert.pem': No such file or directory (VM: HostedEngine, Source: hej1.5ervers.lan, Destination: hej3.5ervers.lan)

Re: Question about Template and Storage Domain
by Eyal Shenitzky
Hi,
You are probably creating the VM as a dependent on the template (thin VM),
it means that the VM's disk should be created on the same storage domain as
the template disk.
In order to create the VM with a disk on a different storage domain, you
can either create the VM as an independent (clone) or copy the template
disk to the storage domain you want to create the VM disk on.

Libgfapi considerations
by Jayme
Are there currently any known issues with using libgfapi in the latest
stable version of ovirt in hci deployments? I have recently enabled it and
have noticed a significant (over 4x) increase in io performance on my vms.
I’m concerned however since it does not seem to be an ovirt default
setting. Is libgfapi considered safe and stable to use in ovirt 4.3 hci?
