Home Lab Hypervisor?

Virt-manager vs oVirt, which one is considered more "up to date"?
To me, oVirt was slow. My one host has 8 cores and 96GB RAM and it took a long time to do stuff. That could be because I did the all in one install. But I'm assuming that's what most people here will be doing.
I find straight KVM easy and super fast. I have a smaller LV for the OS and then a large LV for the qcow2 images. A full clone of a template takes about 2 seconds (thin provisioned qcow2).
You can do some pretty cool stuff with libvirt. I have a template that updates nightly without manually spinning up the disk. I have a clone script that clones the template and sets the MAC, then runs virt-customize to set the hostname in the VM, and then finally starts it.

Is oVirt a virtual appliance like XOA?
you have a number of options from installing it on dedicated machines to installing it as an OVA. here the docs

@aaronstuder I've not a home lab. for personal needs I use KVM as my machines run linux on bare metal.

KVM on my Scale cluster. KVM on my laptop machine. Hyper-V cluster just spun up this week (three nodes.)

Why are you using Hyper-V?

Two KVM servers on CentOS 7.
You need 2x CentOS 7 vm's to run oVirt?

@FATeknollogee no, two physically host. 1 is none, 2 is one.

You have 1 host. What would you do if that host dies? You're left with none. If you have 2, and 1 dies, then you're left with 1.

Yeah, doing a small Starwind Grid.

It's very small. Three Dell R510.

I'm not running oVirt. Just bare CentOS 7 with KVM.
One host has an NFS share because it has bigger disks. The other has more RAM so it has most of the VMs running.
I can transfer them between the hosts but I don't usually do that.

Hyper-V. It's what I have been rolling for production so it only makes sense to have it in my lab so I can test stuff.

This is very correct approach IMHO.

Well that is because you are baking in Veeam.

Hyper-V is a great hypervisor, too... there are few reasons not to use it, and most of those reasons have nothing to do with Hyper-V itself.
