Hi Moti,
=20
Thanks a lot. Do you think we lost functionalities? like server =
migration?
The other way should be creating a new cluster, configure the old =
hosts on this new cluster. Is possible to share the same GlusterFS =
storage between 2 clusters? Is possible to migrate servers and disks =
between the 2 clusters?
migration is supported only within 1 cluster (except for el6 to el7 =
transition)
using Nehalem just means your QEMUs will run only Nehalem instructions =
even when the host is e.g. SandyBridge and have some more advanced =
instructions available. It will run a little bit slower.

Hi Jose,
=20
The correct way to do it is by:
1. Putting all hosts in maintenance mode
2. Changing the cluster cpu type to the desired one
3. Install the new host
4. Activate the hosts
5. Re-run the vms=20

Hi,
 I'm trying to add a new old host (Intel(R) Xeon(R) CPU  X3430  @ =
2.40GHz Intel Nehalem Family) to oVirt Engine Version: =
3.5.4.2-1.el7.centos.
But I'm getting this error:
host does not meet the cluster's minimum CPU level. Missing CPU =
features : model_SandyBridge

=20
What happen if I lower the cluster CPU type? Do I loose =
functionalities? Do I need to shutdown all VMs before change the cluster =
CPU type?
Do you see any problem here?

Thanks
