Xen Cloud Platform vs Oracle VM (RHEV)?

Question

Xen

You need to raise the virtual machine manager while it works as an advanced virtualbox - One server for both the Host and the virtual storage, over time, you will need to make a reservation (the second host to which the virtual machines will migrate in case the first one fails), there will be a testing server on the virtual machines with Oracle base (not production)
Of the minuses of Xen, I only know the lack of a web panel. Please tell me what you would use for this task and what are the disadvantages of this or that technology.

Answer 1

Oracle VM uses XEN
RHEV uses KVM
Both are web-based.
Oracle recognizes only its own as a hypervisor, at least for some products. Pay attention not to fly off the support.

Answer 2

And what I didn’t see where you will have storage?
If on the first one, and it fails, then how will virtual machines migrate?
I didn’t see much difference between xen and kvm, in libwirth everything is the same in general.
Choose what you know more or feel more comfortable and like.

Answer 3

To begin with, I need an advanced virtualbox, since I don’t have the hardware and knowledge to deploy a full-fledged platform with several hosts and shared virtual storage, in addition, XCP can migrate over the network in the absence of shared storage. The only negative that I heard about is that the hardware in the cluster should be the same.
As I already wrote, I chose XCP only because it turned out to raise the server on one machine without dancing with a tambourine, and then life will show.
