Re: [PATCH 1/2] conf: Introduce mshv hypervisor type

Cloud-Hypervisor supports running guests on Linux Hosts with mshv as the
hypervisor.
This is my first time hearing about the Microsoft Hypervisor with Linux
Dom0, and the docs I find via Google aren't entirely conclusive.
Am I right in thinking that "Microsoft Hypervisor" in this context is
simply Hyper-V, aka, the same hypervisor you traditionally have under
a Windows Dom0 ?
If so then I could think that we probably don't need to have a new
virDomainVirt type enum entry. We could simply use the pre-existing
VIR_DOMAIN_VIRT_HYPERV to represent this configuration in the
cloud-hypervisor configuration.
