live storage migration & export speed
by Роман Черкалин
I'm even wondering who has what speed of export VM or live storage migration?
I just don't understand how to increase it. ZFS replication goes 300-400MB/s with the same load.
With regards,

Broke my GlusterFS somehow
by Abe E
So upon changing my ovirt nodes (3Hyperconverged Gluster) as well as my engines hostname without a hitch I had an issue with 1 node and somehow I did something that broke its gluster and it wouldnt activate,
So the gluster service wont start and after trying to open the node from webgui to see what its showing in its virtualization tab I was able to see that it allows me to run the hyperconverged wizard using the existing config. Due to this i lost the engine because well the 3rd node is just arbiter and node 2 complained about not having shared storage.
This node is the one which I built ovirt gluster from so i assumed it would rebuild its gluster.. i accidentally clicked cleanup which got rid of my gluster brick mounts :)) then I tried to halt it and rebuild using existing configuration. Here is my issue though, am I able to rebuild my node?
This is a new lab system so I believe i have all my vms still on my external HDDs. If I can restore this 1 node and have it rejoin the gluster then great, otherwise whats the best route using the webgui (I am remote at the moment) to just wipe all 3 nodes and start all over again and work it slowly? Is it simply deleting the partitions for the ovirt glusters on each node enough to let me rebuild ?

Install hosted engine using fcoe
by kyles＠aasteel.com
We're building a new cluster, but it utilizes fcoe for our storage. Is there a way to install the hosted engine using fcoe? I am unable to see our LUNs in the ovirt node currently as fcoe isn't enabled.

ansible ovirt_template: follow as replacement of nested_attributes
by Nathanaël Blanchet
Hello,
I was familiar with the ansible fetch_nested/nested_attributes to get
additionnal information from API.
Recently it has been deprecated in order to be replaced by the
"follow(s)" verb.
I understand it will follow the links into the schema definition of the
object like:
<link
href="/ovirt-engine/api/templates/e020281a-f5f0-4d98-91e3-4f3a9fc069b1/permissions"
rel="permissions"/>
<link
href="/ovirt-engine/api/templates/e020281a-f5f0-4d98-91e3-4f3a9fc069b1/tags"
rel="tags"/>
<link
href="/ovirt-engine/api/templates/e020281a-f5f0-4d98-91e3-4f3a9fc069b1/cdroms"
rel="cdroms"/>
<link
href="/ovirt-engine/api/templates/e020281a-f5f0-4d98-91e3-4f3a9fc069b1/nics"
rel="nics"/>
<link
href="/ovirt-engine/api/templates/e020281a-f5f0-4d98-91e3-4f3a9fc069b1/watchdogs"
rel="watchdogs"/>
<link
href="/ovirt-engine/api/templates/e020281a-f5f0-4d98-91e3-4f3a9fc069b1/diskattachments"
rel="diskattachments"/>
<link
href="/ovirt-engine/api/templates/e020281a-f5f0-4d98-91e3-4f3a9fc069b1/graphicsconsoles"
rel="graphicsconsoles"/>
but I can't get fetch nested (name of cluster) of :
<cluster
href="/ovirt-engine/api/clusters/bbeb38a4-79f0-11ec-86cb-00163e6d6a50"
id="bbeb38a4-79f0-11ec-86cb-00163e6d6a50"/>
I was used to do this query with:
fetch_nested: yes
nested_attribute:
- name
Is it possible to do the same with "follow(s)"?

VMs losing network interfaces
by Jonathan Baecker
Hello everybody,
I have here a strange behavior: We have a 3 node self hosted cluster
with around 20 VMs running on it. Since longer I had the problem with
one VM that after some days it lose the network interface. But because
this VM was only for testing I was to lazy to dive more in, to figure
out what is happen.
Now I have a second VM, with the same problem and this VM is more
important. Both VMs running debian 10 and use cifs mounts, so maybe that
is related?
Have some one of you seeing this behavior? And can give me a hint, how I
can fix this?
At the moment I can't provide a log file, because I didn't know the
exact time, when this was happen. And I also don't know, if the problem
comes from ovirt or from the operating system inside the VMs.
Have a nice day!
Jonathan

oVirt alternatives
by Thomas Hoberg
There is unfortunately no formal announcement on the fate of oVirt, but with RHGS and RHV having a known end-of-life, oVirt may well shut down in Q2.
So it's time to hunt for an alternative for those of us to came to oVirt because they had already rejected vSAN or Nutanix.
Let's post what we find here in this thread.

Re: ovirtmgmt VLAN and IP Change
by Abe E
Your method worked !
I additionally had to run the engine rename service script to change the hostname of the engine as well.
My only issue now is after readding all the nodes with new hostnames my main host node 1 will not allow me to remove and re-add as a new hostname as there is a gluster volume on it.
It will not let me remove to readd because theres a gluster on the volume, have you run into this?
