Re: Newer kernel for oVirt Node NG
by Shantur Rathore
Tried it again, it just breaks the boot.
After a lot of firefighting found that elrepo kernel-lt doesn't have `xfs`
in initramfs image and it fails mounting the lvm which uses xfs
# lsinitrd /boot/initramfs-4.18.0-240.1.1.el8_3.x86_64.img | grep xfs.ko
-rw-r--r-- 1 root root 442760 Aug 11 2020
usr/lib/modules/4.18.0-240.1.1.el8_3.x86_64/kernel/fs/xfs/xfs.ko.xz
Tested kernel-ml and it has the needed xfs module
After installing the new kernel, I needed to copy over the "options" line
from /boot/loader/entries/ovirt*.conf to the new one.
Hope this saves a lot of hair pulling for someone.

Account on Zanata
by Vasiliy Kovrizhkin
Good day!
My name is Vasiliy and I am searching for some localization of oVirt (or
maybe i make my custom translation of user interface).
Please, can you make an account for me on Zanata?
Thank you!

OVirt rest api 4.3. How do you get the job id started by the async parameter
by pascal＠butterflyit.com
I am using the rest api to create a VM, because the VM is cloned from the template and it takes a long time, I am also passing the async parameters hoping to receive back a job id, which I could then query
https://xxxxx/ovirt-engine/api/vms?async=true&clone=true
however I get the new VM record which is fine but then I have no way of knowing the job id I should query to know when it is finished. And looking at all jobs there is no reference back to the VM execept for the description

Re: HostedEngine VM Paused after power failure
by Ian Easter
Robert,
I understand the sentiment of the difficulty here. The recovery feels
brutal but the monolithic nature and the dense ecosystem is understandable
for the purpose it serves.
I am able to mount the raw disk image for the HostedEngine VM cleanly
without any errors and it seems to check out, so I don't believe there is
any corruption.
Everything looks to operate as expected and then it just seems to snag
somewhere through the startup. I suppose I'm just trying to trace down the
hiccup to clear it out of the way and let the VM boot up. My knowledge is
a bit limited digging in and troubleshooting the components here.
Additional snippet:

Single Node Hyperconverged - Failing Gluster Setup
by jhamiltonactually＠gmail.com
Ovirt newbie here - using v 4.4.4
Have been trying for days to get this installed on my HP DL380p G6. I have 2 disk 170GB Raid 0 for OS and 6 x 330GB disk Raid 5 for Gluster. DNS all set up (that took some working out), but I just can't fathom out whats (not) happening here. Block size is returned as 512.
I've had some help on Reddit where I've been told that Ovirt is seeing my single local disk ass an multipath device, which it is not/??! I think I removed the flag, but it still fails here.
So, Gluster install fails quite early through, though it carries on creating all the volumes (with default settings) but then gives me the 'Deployment Failed' message :( Here is where it fails....
Any help gratefully received!

HostedEngine VM Paused after power failure
by Ian Easter
Hello Users,
We have an oVirt (4.4) environment that had 2 hosts in the cluster. We
suffered from a power failure that caused the servers to be offline for
some time. Once restored, one of the hosts from the cluster lost its OS
raid and is not accessible.
The other server has the HostedEngine vm on it but in a paused state. I
have tried to manually start the vm with the hosted-engine CLI tool but it
indicates that HostedEngine is running on another host.
Is there any manual intervention I can accomplish here to start the
HostedEngine on the second, active host server?
*Thank you,*

Random Crash
by francesco＠shellrent.com
Hi all,
I'm experiencing random reboot on several oVirt nodes (CentOS 7/8, oVirt 4.3/4.4 as well). Sometimes it happens three times in a day, and the more hosts I'm adding to my pool, the more I noticing.
The logs are not helpful: it's like a brute poweroff cause there are no entries at all in the messages, vdsm, secure (I looked all over the logs) from the last "normal" entry (user logged in/off, normal vdsm log ecc.) until the first entry of the boot. kdump is enabled and /var/crash is empty. I used to run Xen on the servers of the same provider and I didn't have all of these frequent reboots, that's why I'm not sure it is a hardware related issue.
Any advice on what enables for getting more info about this crash?
Thank you for your time,
Francesco

Newer kernel for oVirt Node NG
by Shantur Rathore
Hi oVirt Users,
I am trying to test some vfio related stuff on oVirt Node NG 4.4.4 based
host.
What would be the easiest way to have a 5.x kernel on this node?
I don't mind compiling if it needs to.
Cheers,
