[ovirt-users] el9 official use?

[Nathanaël Blanchet via Users]

Hello,
Until 4.5.4, el9 ovirt-node was for testing. Following 4.5.4 releases note, it 
seems to be officially supported but there is no information about el9 engine 
support.
What about it?

I think so, yes.

Not sure. Perhaps ask on the virtio-win project.

My intuition says it might affect performance, but I do not know the
specifics well enough.

Not sure. Perhaps check qemu/libvirt documentation/lists/etc. But
perhaps the impact is not due to them but due to how Windows (and
perhaps the application?) behaves based on the "available" cpu
cores/sockets. E.g. Perhaps with physical 4 sockets compared to 2x2 -
where if it was a physical machine, it would affect caching, I guess -
Windows/app would optimize memory allocation/use differently.

Best regards,

[ovirt-users] Re: Please, Please Help - New oVirt Install/Deployment Failing - "Host is not up..."

[kura_amp]

Hello Dulux-Oz

Thanks for your rep, good to know working fine.
Then, what was the problem of the "Host is not up..." issue and how did *you* 
solve that..?
Hope my question not bother you.

Regards, 
Shin

[ovirt-users] Re: oVirt Update Errors

[duluxoz]

Don't sweat it - If you knew the amount of similar-type errors I've 
coded, allowed my (projects') people to code, and/or simply "missed", 
you'd know I'm the last person to caste a stone.


But as long as I/we get there in the end...  :-)

Cheers

Hi,

unfortunately I made a mistake during the release, 
ovirt-hosted-engine-setup-2.7.0 was not included in the release:

But now it's on the way to mirrors ...

Sorry for the mess.
