Solved KVM nested virtualization ? stable and why would you ?
-
One use of nesting that I know of is when a vendor demands that you run a specific hypervisor, like VMware ESXi, and will not support you unless you do; but you run KVM or Xen in production. You can virtualize the hypervisor for that vendor to meet their support requirements without changing your core infrastructure.
But that's pretty weak versus just replacing the vendor, in most cases.

Its posts/replies like this, makes me wonder why this site does not have ''mark as solution'' option given to the topic opener, and when done the topic will have green color for example.
But maybe that will be a double edge sword, cause it will block future answers and thinking on the topic...

The topic opener can do that. First the topic opener must market as a question. Then the topic opener can market individual solution as an answer.

I did it for you, assuming that I picked the response that you meant. There is the functionality that you want, it just isn't as obvious as you'd hope.

Not sure, just wondered what everybody else uses that tech for.
Nothing at all
It's a neat idea, I wish that VirtualBox had it to make testing on my laptop a little easier for playing with different hypervisors, but outside of that, it's effectively a useless technology. I'm not aware of any real use of it in production.You could just run KVM on your laptop and then you would be able to do that.

Does KVM give you local console/GUI access?

He is already running Linux, but not sure what flavor. So in theory he could use KVM there and still see desktop. Not what you would ever do on a server, but for his laptop? Sure.

Interesting - OK so installing KVM does what hyper-V does, installs the hypervisor under the installed OS and then gives you full local access to Dom0? nice

No, KVM has no Dom0. It's more like VMware ESXi. There is no "underneath" like with Xen or Hyper-V.

This is where KVM and ESXi have a superior architecture. No need for a Dom0 VM.

uhhh.. ok - then can you do what JB suggested? Install KVM into your CentOS that's already on your laptop?

That's what Boxes is.

Ya don't use that crap though. I run VirtManager on my laptop. The console full screen through SPICE is awesome. Even over the network, on a LAN you could think you're using that machine instead of a VM.
