[ovirt-users] Re: Host fails to enter in maintenance due to migration failure

[eevans]

A separate migration network wouldn’t help you. I’m trying to figure out why it 
would be stuck migrating one vm for 20 hours. Something has to be preventing it.

What is your setup? Have you looked at the engine.log or the vm log in 
/var/log/libvirt/qemu/.log?

Hi Eric, thanks for the reply. 

 

Actually putting the host to activate did stopped the maintenance and aborted 
the migration. Thank you for that.

 

Regarding the segregated motion network, I don’t have additional physical 
interfaces, I can only do it on a VLAN. I don’t know if this would help…

 

The attached picture shows my networks.

My question is, are you using a migration network separate from ovirtmgmt 
network? That would probably speed things along for you.

Hello,

I’ve a host that’s preparing to maintenance for almost 20 hours now.

There’s a huge VM on it, with 32 gigs of RAM and this VM is failing migration.

So, there’s a way to cancel prepare for maintenance, so the host can stop 
trying this migration that’s end up failing?

I can just shutdown the VM to do the maintenance on the host...

Thanks,

[ovirt-users] Re: oVirt 4.4.0 Beta release refresh is now available for testing

[eevans]

Correct me if I am wrong, but isn't Ovirt an HA cluster? I assume pacemaker 
would be for specific apps like httpd or database, correct? Gluster is more of 
a distributed file system. I'm just wondering with the performance complaints 
with gluster if there wouldn't be a better solution.

Just thinking out loud.

if I'm not mistaken, these two have different purposes: gluster(fs) is a

[ovirt-users] engine certificate problems in MacOS Catalina

[Jayme]

I recently setup a new ovirt environment using latest 4.3.9 installer. I
can't seem to get the novnc client to work for the life of me in safari or
chrome on MacOS catalina.

I have downloaded the CA from the login page and imported it into keychain
and made sure it was fully trusted. In both system and login keychains.

Looking at this: https://support.apple.com/en-us/HT210176 seems to suggest
that the certificate may be invalid if the issue date is longer than 825
days. The certificate generated by ovirt installer seems to be valid for 5
years. I'm not sure if this is the issue or something else is wrong but if
cert length is a problem is there a way for me to re-regenerate a new
certificate with a shorter issue period?

[ovirt-users] One more time

[eevans]

I have thought about the issue with Windows vm's reporting the timezone 
incorrectly. I reaqlized that just last month, before I created my vm's that 
the  Daylight Savings Time took affect moving our time up 1 hour. SO, based on 
that, instead of setting my time zone to US Eastern (GMT -5), I set it to SA 
Western (GMT -4) and the nasty exclamation mark disappeared. 
This tells me that DST (Daylight Savings Time) is not an option or configurable 
in Ovirt. I think this should be an easy fix for those of use that are stuck 
with it. 
I don't think the rest of the world participates in DST but most of the United 
States does. It would be nice to have those zones added as a configurable 
option that would switch on the dates it is nationally indicated to change.
 
I hope the developers read this.
Thanks.

[ovirt-users] Re: export vm from 3.4 to 4.3

Jaymie has a ansible playbook that will export and backup vm’s. I’ll see if I 
can find it and pass it along. I’m not sure if it will work on 3.5. Have you 
tried importing the vm? You can import from a kvm host so I’m sure it should be 
a similar process.

Not yet. There was the issue with glusterfs storage domain and storage domain 
blocksize probe check.

This is addressed with a new ioprocess-1.4.1 package for the bug[1].

 

We are testing currently with this fix and it works well. But hitting yet 
another issue, where Hosted Engine deployment

fails at the very last stage in the deployment. Gluster developer is looking in 
to it, as I respond here.

Soon we will have a working build and I will let you once these issues are

Thanks for the message. Looking through the logs I saw references to the 
blocksize but since that is contained in the ansible scripts which get 
downloaded to the host I gave up finding the source versions to try to see it I 
could get it going beyond that failing step. 

Anyway, thanks for informing me,

It’s not going to work from 3.5 to 4.3 directly
If you have an old setup with those VMs then just incrementally upgrade.

[ovirt-users] Re: oVirt thrashes Docker network during installation

[Jp]

KubeVirt.  https://kubevirt.io/

Otherwise, your hosts are managing VMs as threads and containers as threads, 
side-by-side, without awareness of conflict.

Ex: dockerd expects to manage its network for containers, and oVirt expects to 
manage a network (bridge) for VMs.  Docker will be expecting to have iptables 
work for it, and then oVirt too!  https://docs.docker.com/network/, and 
https://www.ovirt.org/documentation/installing_ovirt_as_a_standalone_manager_with_local_databases/#general-requirements

You'll have to manage the conflicts yourself without KubeVirt.

If I understand correctly, you are talking about the storage replication
that performed on the storage layer.
This question should refer to the Gluster team/community.

First, I suggest you to use the python scripts that help you to automate
the DR process, you can find them under -
../your-dr-folder/files  -> please use './ovirt-dr -h' to see the
available options.

According to the error, it seems like maybe you didn't wait for the sanlock
lease to expire, you must wait around 80 seconds before you are trying to
use it.
