Hello, I'm looking for better ways to check for bhyve support / available features without trying to scan through dmesg output. I notice that the following 2 sysctl's appear to be set to 1 as soon as the vmm module is loaded hw.vmm.vmx.initialized: 1 hw.vmm.vmx.cap.unrestricted_guest: 1 Will these be available on both Intel & AMD processors as a way to determine if the module has loaded successfully and can run guests? I also see the below sysctl related to iommu. hw.vmm.iommu.initialized Again, will this be set to 1 as soon as the module is loaded if iommu is supported, or only when it is used? There also seems to be a vmm.amdvi.enable sysctl. Would both these need checking or is vmm.iommu enough to determine support on any processor. Matthelp
