This was already discussed in the differential revision of= the change for Xen: https://reviews.freebsd.org/D43508 So the question boils down to whether FreeBSD wants to treat KVM with HyperV extensions as HyperV or as KVM. I think the latter, as KVM is the real hypervisor, disguising as HyperV. --=20 You are receiving this mail because: You are the assignee for the bug.=
