Theoretically nested virt isn't anything for FreeBSD to worry about; it just sees that the CPU it's running has the VMX extensions, and uses them. It's = only the L0 bare metal hypervisor that has to care about nested. The FreeBSD VM immediately locks up as soon as I try to start bhyve in it. --=20 You are receiving this mail because: You are the assignee for the bug.=
