Hi all,

I am a noob in KVM. I am a VMware engineer.
I have created a lab environment to where i have hosted KVM as nested hypervisors within esxi.
I have a vsan environment. I want to create a similar KVM environment.

hence, i have deployed 3 kvm hypervisors (nested)
i have deployed Ovirt-manager ( equivalent to vcenter) to host/manage my KVM hypervisors.
to deploy Ovirt-manager, i installed ovirt packages in centos VM. Because ovirt pacjages are not available in ubuntu, hence choose centos.

next is i want to add kvm hypervisors on ovirt manager similar to how we add esxi hosts to vcenter.
That is where i am failing.
From my limited understanding in KVM, ovirt is looking for yum package manager , KVM are ubuntu flavoured, hence it has apt package manager.

What my ask is, can this be fixed? is there a file i need to edit in ovirt-engine.?
Can Ovirt-manager host KVM of ubuntu flavour?
Please advise.
Checked the ovirt logs:
