Bugzilla Automation <bugzilla@FreeBSD.org> has asked vbox@FreeBSD.org for maintainer-feedback: Bug 239835: emulators/virtualbox-ose doesn't recognize AMD Ryzen 7 3800X "S= VM" feature - won't allow 64-bit guests https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D239835 --- Description --- H/W: AMD Ryzen 7 3800X CPU, MSI MEG X570 ACE MB (no option to enable or dis= able virtualization) Relevant DMESG line:=20 AMDFeatures2=3D0x75c237ff<LAHF,CMP,SVM,ExtAPIC,CR8,ABM,SSE4A,MAS,Prefetch,O= SVW,IB S,SKINIT,WDT,TCE,Topology,PCXC,PNXC,DBE,PL2I,MWAITX, AMD Virtualization Reference: https://en.wikipedia.org/wiki/X86_virtualization#AMD_virtualization_(AMD-V) Relevant text: 'The CPU flag for AMD-V is "svm". This may be checked in BSD derivatives via dmesg or sysctl and in Linux via /proc/cpuinfo.' Previously created 64-bit VBox machines on earlier H/W and VBox are no long= er "defined" as 64-bit machines. All machine type selections are now 32-bit on= ly (see 'FBSD-VBox-5.2.18_no_64_bit.png' screen shot). Attempting to start a previously configured 64-bit VM now results in an err= or message (see 'FBSD-VBox-5.2.18_no_VTx_AMD-V_HW.png' screen shot) which furt= her informs that CPU virtualization support is "missing".
