Re: 4.2.8 to 4.3.7 > Management slow
by Strahil
You can manually change the I/O scheduler of the disks and if that works better for you, put a rule in udev.
Here is mine:
[root@engine rules.d]# cat /etc/udev/rules.d/90-default-io-scheduler.rules
ACTION=="add|change", KERNEL=="sd*[!0-9]", ATTR{queue/scheduler}="none"
ACTION=="add|change", KERNEL=="vd*[!0-9]", ATTR{queue/scheduler}="none"
[root@engine rules.d]# cat /sys/block/vda/queue/scheduler
[none] mq-deadline kyber

Re: I am interested in using oVirt for my homelab but is it dead?

I was reading about oVirt and it sounded promising, I saw all the Ansible roles. I installed ovirt on CentOS 8 (and used the Ansible roles from the Galaxy) and hit few strange walls like the standard SSL cert not being accepted by Google Chrome on Mac OSX with error "revoked". Additionally the community seems so small compared to others (like Proxmox).
Current stable is 4.3.X based on EL7. Anything above might have issues.

Not only Red Hat, but also Oracle is now providing their own solution based on Ovirt, so you can expect it won't be dead any time soon. The project is good and the community will never ignore you.
Don't forget that this is the upstream of RHV/OVM and as every upstream there will be bugs (so far nothing serious).

Re: Issue deploying self hosted engine on new install
by thomas＠hoberg.net
Yes, I have had the same and posted about it here somewhere: I believe it's an incompatible Ansible change.
Here is the critical part if the message below:
"The 'ovirt_host_facts' module has been renamed to 'ovirt_host_info', and the renamed one no longer returns ansible_facts"
and that change was made in the transition of Ansible 2.8* to 2.9, from what I gathered.
I guess I should just make it a bug report if you find the same message in your logs.
