I'm not doing a oVirt update, I'm just deploying a fresh.
I just ssh to the engine via the ip in /etc/hosts.
And then use the downgrade command after wizard has run upgrade.

Hi,
After HE deployment my oVirt nodes keeps updating and rebooting, even though I

What is the alternative for this in oVirt?
Achieving Non-stop Service for legacy statefull application that doesn't
support it by itself.
The virtualization layer is the perfect place to implement this functionality.

Will COLO be implemented in oVirt?
Is it possible to do it myself? I see qemu-kvm and lots of other qemu installed

Why does the HE Deployment Not deploy a hosted engine dc and cluster which fits
the host in version?
My Hosted Engine Deployment now fails again because of "Host hej1.5ervers.lan
is compatible with versions (4.2,4.3,4.4,4.5) and cannot join Cluster Default
which is set to version 4.6."
I think
When I put in the "/etc/pki/CA/cacert.pem" from the old node, I just get next
error as follows:

Hi,
In the second engine dep run in Hyperconverged deployment I get red "Ooops!" in
cockpit.
I think it fails on some networking setup.
The first oVirt Node says "Hosted Engine is up!" but the other nodes is not
added to HostedEngine yet.
There is no network connectivity to the Engine outside
Ok guys now my setup it like this:
2 x Servers with 5 x 4TB 7200RPM drives in raidz1 and 10G storage network (mtu
9000) in each - my gluster_bricks folders
1 x SFF workstation with 2 x 50GB SSD's in ZFS mirror - my gluster_bricks
folder for arbiter
My gluster vol info looks like this:
Volume
So my gluster performance results is expected?

Hi,
Can anyone help me with the performance on my 3 node gluster on zfs (it is
setup with one arbiter)
The performance on the single vm I have on it (with engine) is 50% worse then a
single bare metal disk, on the writes.
I have enabled "Optimize for virt store"
I run 1Gbps 1500MTU network,
It works, thanks! You can do magic.
