Does anyone know How to install macOS on ovirt4.4?
I used the image--"macOS.Big.Sur.11.2.3.20D91.iso"，It can run successfully on VMware.But on ovirt，I tested the boot type by both UEFI and BIOS ,they are all cant boot

Reconfigure Gluster from Replica 3 to Arbiter 1/Replica 2
by David White
My current hyperconverged environment is replicating data across all 3 servers.
I'm running critically low on disk space, and need to add space.
To that end, I've ordered 8x 800GB ssd drives, and plan to put 4 drives in 1 server, and 4 drives in the other.
What's my best option for reconfiguring the hyperconverged cluster, to change gluster storage away from Replica 3 to a Replica 2 / Arbiter model?
I'd really prefer not to have to reinstall things from scratch, but I'll do that if I have to.
My most important requirement is that I cannot have any downtime for my VMs (so I can only reconfigure 1 host at a time).

Automatic Shutdown / Startup for Hosted-Engine
by Eugène Ngontang
Hi,
I understood we have to put hosted-engine into maintenance mode and
shutdown the VMs if we want to power off the host (otherwise it will
reboot). I'm setting up a process to
- put the HestedEngine in global maintenance mode (*hosted-engine
--set-maintenance --mode=global*)
- shutdown the HostedEngine (*hosted-engine --vm-shutdown*)
- PowerOff the HostedEngine (*hosted-engine --vm-poweroff*)
- Power off the server (*shutdown -P*)
Everything works fine and I can start the server back up, remove the
HostedEngine from maintenance mode, and it will start automatically
running. The issue is when bringing up hosted-engine: all VMs come up but
one (*BigIP*) and I am trying to see if there is way to bring it up without
having to store the engine password (using the *ovirt_vm* API).
At the moment, I am having to look for the BigIP VM and then use
credentials to bring it up: it will not come up with 'hosted-engine
--vm-start'
Is there to make this specific VM start the same time as the others VM
automatically when HostedEngine starts?
Thanks for your help.
Regards,
Eugène NG

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!

ovirt (two nodes & iscsi san)
by edp＠maddalena.it
Hi.
i am trying to set up an environment with two ovirt nodes connected to a san in iscsi.
every node has a direct connection to the san (with a point-to-point connection).
so every node talks with the san on a different iscsi channel with a different ip.
in this case (i have just tried) when I shut down ovirt-node1 the ovirt-engine cannot restart automatically on ovirt-node2.
maybe this because when I have configured hosted engine I have moved the engine storage to the iscsi lun that only the node1 can see (the ovirt-engine-setup asks for the iscsi ip address).
In this case how can I resovle my problem?
other than moving the ovirt-engine from one node to the other I have also to publish other luns to both ovirt nodes.
but if every node talks only with one channel of the iscsi san I think that this won't working.
If i put a 10 gb switch between ovirt-nodes and san channels can working?
what I would like to do is connect the two ovirt nodes to the switch and also the two iscsi channels of the san to the switch.
in this way each node should be able to talk to the san on both ip (iscsi channels)
thank you

random adapter (NIC) resets on oVirt Node 4.4.6
by Tivon Häberlein
Hi,
I've been trying to get oVirt Node 4.4.6 up and running on my Dell r620
hosts but am facing a strange issue where seemingly all network adapters
get reset at random times after install.
The interfaces reset as soon as a bit of traffic is flowing through them.
Also the logs show nfs timeouts.
This only happens after I have installed the host using the oVirt engine
and it also only happens when the host is connected to the engine. When
the host is in maintenance mode it also seems to work fine.
The host and networks work fine when its by itself (I tested right after
install using the ISO and also after I have removed the host from the
cluster)
I cant figure why this is happening. Am I missing something?
I've been stuck on this for the last couple of weeks, a bit of help
would be much appreciated.
Thank you!
My cluster is looking like this:
Engine: oVirt 4.4.6 - CentOS Linux release 8.3.2011
host1: oVirt 4.4 repository on CentOS Linux release 8.4.2105
host2: oVirt 4.4 repository on CentOS Linux release 8.4.2105
host3 (this is the one I'm trying to install): oVirt node 4.4.6

Hi Marko,
I don't think there is a way to emulate a non-native architecture.
Engine doesn't have ARM support and it cannot handle ARM (native or
emulated) hosts. You could try to run emulated ARM VMs presented as x86
to Engine using Vdsm hooks but I doubt it would work.
I'm afraid the only way is to add ARM support to oVirt. My former
colleague has played with running oVirt on Raspberry Pi hosts some years
ago (there are traces of that effort in Vdsm) and I think adding ARM
support should be, at least in theory, possible. Particular features
available would be mostly dependent on ARM support in QEMU and libvirt.
Regards,
Milan
