[ovirt-users] Re: Question on "Memory" column/field in Virtual Machines list/table in ovirt GUI

[KISHOR K]

Hello,

Sorry,  yes i meant a bug in ovirt with SLES, not in SLES :). 
Now, I understand all the details. Thanks a lot !
I will then open a bug as suggested, never did it before but hope it will be 
easy :)

[ovirt-users] oVirt Survey Autumn 2020

[Sandro Bonazzola]

As we continue to develop oVirt 4.4, the Development and Integration teams
at Red Hat would value insights on how you are deploying the oVirt
environment.
Please help us to hit the mark by completing this short survey.
The survey will close on October 18th 2020. If you're managing multiple
oVirt deployments with very different use cases or very different
deployments you can consider answering this survey multiple times.

*Please note the answers to this survey will be publicly accessible*.
This survey is under oVirt Privacy Policy available at
https://www.ovirt.org/site/privacy-policy.html .

[ovirt-users] info on iSCSI connection setup in oVirt 4.4

[Gianluca Cecchi]

Hello,
supposing to have a node that connects to an iSCSI storage domain in oVirt
4.4, is there any particular requirement in the configuration of the
network adapter (ifcfg-eno1 file) when I pre-configure the server OS?
Eg, do I need to have it managed by NetworkManager in 4.4? Can I instead
set NM_CONTROLLED=no for this controller?
Thanks in advance,
Gianluca

4.4 is using NetworkManager, so it is unlikely be able to manage the nic in the
suggested configuration.

Adding Ales to add more info on this.

As Nir said, 4.4 is using NetworkManager to manage every network on the
host.
What would be the reason to disable it? The networking should work the same
way at least from
oVirt point of view.

In this particular case I would like to see if NetworkManager could be in
any way responsible for some disconnect/reconnect events we are registering
when pushing to the iSCSI storage.
But I'm not sure about it, only a test I would like to do (mainly to
exclude it), as I also see NetworkManager registered events about the state
of the link.
I'm more inclined to think that the problem could be related to the ixgbe
10gb kernel module shipped with 4.4.1 ovirt node ng.
we see this in messages:

Other 4.4.1 nodes with different network adapters and connected to the same

Any suggested way to substitute the provided module (5.1.0-k-rh8.2.0) of
kernel 4.18.0-193.14.2.el8_2.x86_64 with a more recent one and see if it
solves the problems? Or suggestions regarding iscsid.conf customization if
using ixgbe based network cards...?

Thanks,
Gianluca

[ovirt-users] Re: oVirt - Gluster Node Offline but Bricks Active

[Jeremey Wise]

in oVirt Engine I think I see some of the issue

When you go under volumes -> Data ->

[image: image.png]

It notes two servers..  when you choose "add brick" it says volume has 3
bricks but only two servers.

So I went back to my deployment notes and walked through setup

yum install https://resources.ovirt.org/pub/yum-repo/ovirt-release44.rpm -y

[ovirt-users] Installed oVirt 4.4.2 on CentOS 8

[info]

New oVirt basic installation on Centos 8 as a physical server. The default
Data center in an uninitialized state

 

This is my first working installation and I have no idea what to do next. 

 

Anyone knows a step by step guide for fresh install?

 

Any advice will be appreciated.

[ovirt-users] ISO Repo

[Jeremey Wise]

I saw notes about oVirt 4.4 may no longer support ISO images... but there
are times like now I need to build based on specific ISO images.

I tried to do a cycle to create an image file 8GB  then do dd if=blah.iso
of=/

Created a new vm with this as boot disk and it fails to boot...  so.. back
to "create volume for iso images"

But when I do that I get error

New Domain -> "Domain function" =iso  Storage type = glusterFs
Use Managed Gluster volume -> Select already working gluster file space
"thor.penguinpages.local:/iso
VFS Type: glusterfs
mount
options: 
backup-volfile-servers=odin.penguinpages.local:medusa.penguinpages.local


Error:
Error while executing action: Cannot add Storage Connection. Performance
o_direct option is not enabled for storage domain.

Questions:
1) Why did the image and dd of iso to boot disk not work?
2) Any ideas about create of iso mount volume?

[ovirt-users] Gluster Volumes - Correct Peer Connection

[Jeremey Wise]

I just noticed when HCI setup bult the gluster engine / data / vmstore
volumes... it did use correctly the definition of 10Gb "back end"

But..  oVirt Engine is NOT referencing this.
it lists bricks as 1Gb "managment / host" interfaces.  Is this a GUI
issue?  I doubt this and how do I correct it?

4.4 supports iso images of course.

The note is about ISO storage domain - this is a special storage
domain that can be created
only on NFS, and can hold only ISO images. To add ISO images to this
special storage domain,
you had to use a special iso uploader program, or add manually to the
right place in the storage
domain directory, and make sure the permissions are correct. This
storage domain type was
deprecated several version ago, but it is still available.

Since 4.2 (or maybe even before that) you can upload ISO images to
data domain of any type
(e.g. NFS, Gluster, iSCSI, FC). Upload is available via the
administration portal, or via the
API/SDK, same as other image types.

Note that there is an issue on block storage data domain, preventing
changing CD on a running
VM. We are working on fixing this for 4.4.3.

I'm not sure what you tried to do.

Your gluster volume is not configured properly for ovirt. Did you add
the volume via the administration portal?

Why do  you need special gluster volume for ISO images?

> Questions:

We don't have enough information here to tell.

> 2) Any ideas about create of iso mount volume?

Yes:
1. Visit  Storage > Disks
2. Click Upload
3. Select ISO image
4. Select storage domain to upload the image
5. Click "Upload"

Might I suggest that you folks revisit the issue of what to do with the 
"guest tools iso". Since supposedly they are,

"provided by the oVirt-guest-tools-iso package installed as a dependency
 to the oVirt Engine. This ISO file is located in
 /usr/share/oVirt-guest-tools-iso/oVirt-tools-setup.iso on the system 
 on which the oVirt Engine is installed."


https://www.ovirt.org/documentation/vmm-guide/chap-Installing_Windows_Virtual_Machines.html

(the package is no longer an automatic dependancy either. at least for 
hosted-engine)

[ovirt-users] Re: ISO Repo

[Philip Brown]

well, I havent used it before :)

I just discovered that some windows VMs of ours needed guest additions, and 
looked for the right way to handle it for ovirt.

OH. I think you are implying perhaps that modern windows VMs automatically have 
hooks for virtual hosting?
Sad to say, these are ... "older"*cough*   Vms.

[ovirt-users] Re: Node upgrade to 4.4

[Vincent Royer]

My confusion is that those documents do not describe any gluster related
tasks for Ovirt Nodes.  When I take a node down and install Ovirt Node 4.4
on it, won't all the gluster bricks on that node be lost?  The part
describing "preserving local storage", that isn't anything about Gluster,
correct?

I don't know how the windows guest tools are shipped now, but Gal should know.

If you have this ISO, you can upload it to some data domain. After that you can
attach it to any VM.

[ovirt-users] Re: Node upgrade to 4.4

[Strahil Nikolov via Users]

Before you reinstall the node , you should use 'gluster volume remove-brick 
 replica  ovirt_node:/path-to-brick' to reduce the volume 
to replica 2 (for example). Then you need to 'gluster peer detach ovirt_node' 
in order to fully cleanup the gluster TSP.

You will have to remove the bricks that are on that < ovirt_node > before 
detaching it.

Once you reinstall with EL 8, you can 'gluster peer probe 
' and then 'gluster volume add-brick  replica 
 reinstalled_ovirt_node:/path-to-brick.

Note that reusing bricks is not very easy, so just wipe the data via 'mkfs.xfs 
-i size=512 /dev/block/device'.

Once all volumes are again a replica 3 , just wait for the healing to go over 
and you can proceed with the oVirt part.

Strahil Nikolov

[ovirt-users] Re: ISO Repo

[penguin pages]

This is close to all i need.

I did upload the iso as image.. but how do you attach it to the VM ?   I 
assumed that issue was a 4.4 changes / constrain.
 It was a miss-interpretation on my part that ISO use was relegated to being 
only as a "volume" independent.

As such.. I went back to uploading iso images.  They are now "images" in disk.

Going to VM: select vm -> Disks -> VM Devices -> "edit virtual machine" -> Boot 
Options -> "attach CD" -> "whoot!!!"

ISO images now show as attachable option.

Thanks.. All good.

[ovirt-users] Re: Node upgrade to 4.4

[Michael Thomas]

Not to give you any false hope, but when I recently reinstalled my oVirt 
4.4.2 cluster, I left the gluster disks alone and only reformatted the 
OS disks.  Much to my surprise, after running the oVirt HCI wizard on 
this new installation (using the exact same gluster settings as before), 
the original contents of my gluster-based data domain were still intact.


I certainly wouldn't count on this behavior with any important data, though.

Before you reinstall the node , you should use 'gluster volume
remove-brick  replica  ovirt_node:/path-to-brick' to
reduce the volume to replica 2 (for example). Then you need to 'gluster
peer detach ovirt_node' in order to fully cleanup the gluster TSP.

You will have to remove the bricks that are on that < ovirt_node > before
detaching it.

Once you reinstall with EL 8, you can 'gluster peer probe
' and then 'gluster volume add-brick  replica
 reinstalled_ovirt_node:/path-to-brick.

Note that reusing bricks is not very easy, so just wipe the data via
'mkfs.xfs -i size=512 /dev/block/device'.

Once all volumes are again a replica 3 , just wait for the healing to go
over and you can proceed with the oVirt part.

My confusion is that those documents do not describe any gluster related
tasks for Ovirt Nodes.  When I take a node down and install Ovirt Node 4.4
on it, won't all the gluster bricks on that node be lost?  The part
describing "preserving local storage", that isn't anything about Gluster,
correct?

[ovirt-users] oVirt 4.3 HCI ovirtmgmt vlan problem

[wodel youchi]

Hi,

I deployed an HCI of three nodes using ovirt 4.3 on a flat network at the
beginning, now we need to use VLAN on the management network.

I have ovirtmgmt over bond2, this bond will have three vlans : vlan 10 for
management, vlan20 for DMZ and vlan30 for DMZ2.

On the switch, I did configure the concerned ports to support ; the native
vlan (untagged), the vlan10 (tagged), ...etc.
Then I activated the tag on the ovirtmgmt network on the web UI, I did lose
connexion to the hypervisors and things got weird, I then put my machine on
vlan10, I saw that two of my hypervisors had their network configuration
modified to use the vlan10, but not the hypervisor where the VM-engine was
running.
I created the vlan manually on that hypervisor, then I started the
VM-Manager, all hosts were recognized.
Then I stopped, then started the platforme again. Still the same problem,
two hosts are correct with their vlan : bond2.10 created, but the third no
vlan.
Doing the configuration manually works, but it does not survive reboot, is
there a way to force vdsm to accept the new configuration on that faulty
host?

Regards.

[ovirt-users] Re: Gluster Name too long

[Parth Dhanjal]

Hey!

This is a known bug targeted for oVirt 4.4.3.
Firstly, multipath should be ideally used when you are not using a RHVH
system.
Then disabling the "blacklist gluster device" option will ensure that the
ansible inventory file doesn't blacklists your device.
In case you have a multipath and you mention that as the device name,
the lvname and thinpool name exceed 55 characters which causes this error.
A workaround can be that you can edit the ansible inventory on the last
step of the Deployment Wizard and use only the last 4 characters of the
multipath for lvname and thinpool name.

If glusterd service is running on the host check whether vdsm-client is
returning gluster host uuid. just run this on the host "vdsm-client

Please follow one of the installation guides.

[ovirt-users] Re: Gluster Volumes - Correct Peer Connection

[Gobinda Das]

But I think this only sync gluster brick status not the entier object.
Looks like this a bug.
@Ritesh Chikatwar  Could you please check what data we
are getting from vdsm during gluster sync job run? Are we saving exact data
or customizing anything?
