2 other VMs have very low disk activity.

I have an oVirt cluster on which I need to change which VLAN is the
The new management network is an existing VM network. I've configured IP
addresses for all the hosts on this network, and I've even moved the
HostedEngine VM onto this network. So far so good.
What I cannot seem to be able to do is actually change the "management
network" toggle in the cluster to this network: the oVirt Engine
"Error while executing action: Cannot edit Network. Changing management
network in a non-empty cluster is not allowed."
How can I get around this? I clearly cannot empty the cluster, as the
cluster contains all my existing VMs, hosts and HostedEngine.
I am having an issue migrating all vm's based on a specific template. The
template was created in a previous ovirt environment (4.1), and all VM's
deployed from this template experience the same issue.
I would like to find a resolution to both the template and vm's that are
already deployed from this template. The VM in question is VDI-Bryan and
the migration starts around 12:25. I have attached the engine.log and the
vdsm.log file from the destination server.
I have Ovirt Version:220.127.116.11-1.el7.centos, I did upgrade according to host
indication ,and since then I get the following error when trying to
activate host " Cannot activate Host. Host has no unique id. "
Any idea how to fix this issue, please advice
In 4.1 i was able to assign 1 user to one VM and in the user portal that
same user was only seeing this specific VM. But with 4.2 i have trouble
The way i add permission to a specific user is go click on the VM in the
admin portal, then go in permission and add the user(active directory
user). If i log back with this user on the user portal i do not see the VM
that was given the permission.
But if i add the same user in the system permission tab in the admin portal
and give it the UserRole and log back to the user portal, now he can see
all the VM but i only want the user to see is vm not all others ...
there is a difference when the is add from the two different place.. is the
when add from the sytem permission it add the (System) in the inherited
when add from the VM permission tab it does not have that..
Any hints would appreciated.
I am new to oVirt. I want to install it on Ubuntu ( oVirt-Engine) , as I do
this for testing for my diploma at university and don't have too much space
on my computer for hundreds of VMs.
What is the status now? I looked on what is written on the site, is it
still true and it can be done through all the hacks listed there?
