Just to be clear, this is a high level of discussion.  Your points are extremely valid, yet specific details, we can work out what should be offered as resources to enhance the development/adoption efforts.

Currently HyperV market share is on the rise, simple due to the fact that it is a cheaper alternative to VMware.

Currently it is estimated that it will reach 30% of overall hypervisor market by the end of the year.

One large segment of virtualization usage is currently rhel/epl on vmware.  I specifically know of extremely large deployments (thousands of epl vms)  currently evaluating HyperV and considering a hypervisor switch due to cost.

I'll look into this.

I agree.

I'm open to this idea as well.   If it's a way for centos users to running on hyperv to install enlightened natively, i'm all for it.
