Hey all, I am utterly confused by this one: I am unable to load vmm.ko nested in KVM. (10.2 on a 2x E5-2620v2 board, linux kernel 4.x for host, kvm/qemu 2.4, proxmox 4.0. Nested bool is set true in module config). `dmesg` prints a message saying that VT-x is "disabled by BIOS" (I passed -L and -bios pointed at OVMF just in case it was a strange SEABIOS compile option) to no change. -cpu is set to host, I have also tried passing -cpu qemu64,+vmx manually to no change. (`kldload vmm` does agree - it says features are missing) Linux appears to have no problems with bringing kvm up nested (I tested kvm -enable-kvm as well to no complaints). What am I missing? model name : Intel(R) Xeon(R) CPU E5-2620 v2 @ 2.10GHz stepping : 4 microcode : 0x1 cpu MHz : 2099.998 cache size : 15360 KB physical id : 0 siblings : 1 core id : 0 cpu cores : 1 apicid : 0 initial apicid : 0 fpu : yes fpu_exception : yes cpuid level : 13 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ss syscall nx pdpe1gb rdtscp lm constant_tsc arch_perfmon rep_good nopl eagerfpu pni pclmulqdq vmx ssse3 cx16 pcid sse4_1 sse4_2 x2apic popcnt tsc_deadline_timer aes xsave avx f16c rdrand hypervisor lahf_lm arat xsaveopt tpr_shadow vnmi flexpriority ept fsgsbase tsc_adjust smep erms (note: this is the VM) Verbose boot info: Oct 14 06:13:10 kernel: CPU: Intel(R) Xeon(R) CPU E5-2620 v2 @ 2.10GHz (2100.02-MHz K8-class CPU) Oct 14 06:13:10 kernel: Origin="GenuineIntel" Id=0x306e4 Family=0x6 Model=0x3e Stepping=4 Oct 14 06:13:10 kernel: Features=0xf83fbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,MMX,FXSR,SSE,SSE2,SS> Oct 14 06:13:10 kernel: Features2=0xffba2223<SSE3,PCLMULQDQ,VMX,SSSE3,CX16,PCID,SSE4.1,SSE4.2,x2APIC,POPCNT,TSCDLT,AESNI,XSAVE,OSXSAVE,AVX,F16C,RDRAND,HV> Oct 14 06:13:10 kernel: AMD Features=0x2c100800<SYSCALL,NX,Page1GB,RDTSCP,LM> Oct 14 06:13:10 kernel: AMD Features2=0x1<LAHF> Oct 14 06:13:10 kernel: Structured Extended Features=0x202<TSCADJ,ERMS> Oct 14 06:13:10 kernel: XSAVE Features=0x1<XSAVEOPT> Oct 14 06:13:10 kernel: VT-x: (disabled in BIOS) Basic Features=0x981000<TRUE> Oct 14 06:13:10 kernel: Pin-Based Controls=0xff<ExtINT,NMI,VNMI,PreTmr,PostIntr> Oct 14 06:13:10 kernel: Primary Processor Controls=0xf7f9fffe<INTWIN,TSCOff,HLT,INVLPG,MWAIT,RDPMC,RDTSC,CR3-LD,CR3-ST,CR8-LD,CR8-ST,TPR,NMIWIN,MOV-DR,IO,IOmap,MSRmap,MONITOR,PAUSE> Oct 14 06:13:10 kernel: Secondary Processor Controls=0x3db<APIC,EPT,RDTSCP,x2APIC,WBINVD,UG,APIC-reg,VID> Oct 14 06:13:10 kernel: Exit Controls=0x981000<PERF,PAT-LD,EFER-SV> Oct 14 06:13:10 kernel: Entry Controls=0x981000 Oct 14 06:13:10 kernel: EPT Features=0x4114040<PW4,WB,2M,INVEPT,all> Oct 14 06:13:10 kernel: VPID Features=0x0 Oct 14 06:13:10 kernel: Data TLB: 1 GByte pages, 4-way set associative, 4 entries Oct 14 06:13:10 kernel: Data TLB: 4 KB pages, 4-way set associative, 64 entries Oct 14 06:13:10 kernel: Instruction TLB: 2M/4M pages, fully associative, 8 entries Oct 14 06:13:10 kernel: Instruction TLB: 4KByte pages, 4-way set associative, 64 entries Oct 14 06:13:10 kernel: 64-Byte prefetching Oct 14 06:13:10 kernel: Shared 2nd-Level TLB: 4 KByte pages, 4-way associative, 512 entries Oct 14 06:13:10 kernel: L2 cache: 256 kbytes, 8-way associative, 64 bytes/line Oct 14 06:13:10 kernel: Hypervisor: Origin = "KVMKVMKVM" Oct 14 06:13:10 kernel: real memory = 4294967296 (4096 MB) Oct 14 06:13:10 kernel: Physical memory chunk(s): Oct 14 06:13:19 kernel: domain=0, bus=0, slot=31, func=3 Oct 14 06:13:19 kernel: class=0c-05-00, hdrtype=0x00, mfdev=1 Oct 14 06:13:19 kernel: cmdreg=0x0103, statreg=0x0000, cachelnsz=0 (dwords) Oct 14 06:13:19 kernel: lattimer=0x00 (0 ns), mingnt=0x00 (0 ns), maxlat=0x00 (0 ns) Oct 14 06:13:19 kernel: intpin=a, irq=16 Oct 14 06:13:19 kernel: pci0:0:31:3: reprobing on driver added Oct 14 06:13:19 kernel: pci1: driver added Oct 14 06:13:19 kernel: pci2: driver added Oct 14 06:13:19 kernel: pci3: driver added Oct 14 06:13:19 kernel: pci4: driver added Oct 14 06:13:19 kernel: pci5: driver added Oct 14 06:13:19 kernel: pci6: driver added Oct 14 06:13:19 kernel: pci7: driver added Oct 14 06:13:19 kernel: pci8: driver added Oct 14 06:13:19 kernel: vmx_init: processor does not support desired basic capabilities Oct 14 06:13:19 kernel: module_register_init: MOD_LOAD (vmm, 0xffffffff81a16fd0, 0) error 2 Thanks! -- -- Cory Smelosky iXsystems
