I had a mac address conflict so reinstalled ( from scratch ) 4.1 this morning, CPU load issue in UI was still there.

We already have an open bug about this: https://bugzilla.redhat.com/show_bug.cgi?id=1390675

Thanks for the report.

I can't deploy additional hosts now though due to SSH errors.

Could you please attach host-deploy logs?

Experimenting, I updated the hosted engine this afternoon and the CPU load issue seems be have either been fixed or resolved itself.

However, SSH errors deploying additional hosts persists ( I had no problem with the previous install on Friday ).

I'm trying to deploy using a password ( which I know is correct ), I think it might be switching to keys when it fails, but I'm only guessing.

Any thoughts on this issue ?

First glance at 4.1

Installation seemed easier than with earlier versions ( but I have installed it a few times now ).
Hosted engine reports 100% CPU usage even if the host is basically idle

I'll feed back more as and when I get chance to use it, feels good so far though.

Keep on with the great work!

Regards,
Brett

Hi,
any feedback on 4.1 beta we released last week?
Thanks,

I see that in storage tab the NFS domain is marked as V4, while in 4.0.5 is marked as V3.
The nfs mount from host is still v3, but I think it is not related and instead V4 refers to functionalities of storage domain itself...

Right.

In this case, where to find V3 vs V4 storage domain features?

http://www.ovirt.org/develop/release-management/features/storage/DataCenterV4_1/ - but it may need some updates.
Y.

There is a more detailed feature page for qcow2v3 which is currently under review, here it is:

https://github.com/maorlipchuk/ovirt-site/blob/cdbbfa5250af0e207ff151af67f188b3451d4c33/source/develop/release-management/features/storage/qcow2v3.html.md

Hi Brett,

Here is the official updated wiki which also consists REST examples:

If you have any questions, please don't hesitate to contact me or the users list
