Hi De Lee,
The directory shared by NFS must be owned by the vdsm user (UID 36) and the kvm
group (GID 36) with 0755 permission.
Also, the share configuration must allow your KVM hosts to connect to it, like:
/share-directoryIP-ADDRESS-OR-HOSTNAME(rw)
OTHER-IP-ADDRESS-OR-HOSTNAME(rw)

Hi,
You cannot run the ovirt-engine service on a KVM host. The server must act as a
hypervisor (KVM host) or the Engine server, not both at the same time. I
understand you are running a lab using VMs. Create two VMs, one for the KVM
host and another for the Engine application.

Hi Shafi,
Creating a thin provisioned disk using a block Storage Domain will allocate
512MB of disk space. I don’t have the values for a file-based Storage Domain.
In a regular VM operation, the disk is increased when it reaches 80% (dev team,
correct me if I’m wrong) of the allocated space
Hi Shafi,
A Storage Domain in oVirt is like a Storage Pool in a stand-alone KVM host.
To create a virtual disk on a stand-alone KVM host, a storage pool must exist
where you create the virtual disk. The same for oVirt, to upload or to create a
virtual disk, a Storage Domain must exist.

The dnsmasq service running on the KVM host manages the IP assignment during

How did you deploy your KVM host? Which configurations have you done on it
