Hello List,
I am facing the following issue when I try to import a VM from a KVM host to my oVirt
(4.4.5.11-1.el8).
The importing I done throuth GUI using the option of KVM provider.

Looks like the disk:

Was created with the wrong initial size.
When importing vms from libvirt I don't think we have a way to get the
required allocation
of the disk, so the disk must be created with
initial_size=virtual_size, and this was probably
not done in this case.
Please file a bug and include full vdsm from the SPM host and from the
host running the
import, and full engine logs. The log should show the creation of the
target disk
cb63ffc9-07ee-4323-9e8a-378be31ae3f7.
You can grep this uuid in vdsm logs (/var/log/vdsm/vdsm.log*) on the
spm host, the host
running the import, and engine host (/var/log/ovirt-engine/engine.log).

The available space on the host is not related, the issue is creating a big
enough disk when creating sparse volume on block storage.

Since you have access to the disk you want to import, you can upload
it to oVirt and create a new vm with the disk, instead of importing via
libvirt.
