https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D246168 --- Comment #7 from John Hartley <drum@graphica.com.au> --- Hi Peter & Co, I reviewed the prior bug report and FYI here is some additional information= on my machine: <<START LAYER 1 - FreeBSD CPU Report from dmesg.boot>> ... ... CPU: Intel Core Processor (Broadwell, IBRS) (2600.09-MHz K8-class CPU) Origin=3D"GenuineIntel" Id=3D0x306d2 Family=3D0x6 Model=3D0x3d Steppi= ng=3D2 =20 Features=3D0xf83fbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,M= CA,CMOV,PAT,PSE36,MMX,FXSR,SSE,SSE2,SS> =20 Features2=3D0xfffa3223<SSE3,PCLMULQDQ,VMX,SSSE3,FMA,CX16,PCID,SSE4.1,SSE4.2= ,x2APIC,MOVBE,POPCNT,TSCDLT,AESNI,XSAVE,OSXSAVE,AVX,F16C,RDRAND,HV> AMD Features=3D0x2c100800<SYSCALL,NX,Page1GB,RDTSCP,LM> AMD Features2=3D0x121<LAHF,ABM,Prefetch> Structured Extended Features=3D0x1c0fbb<FSGSBASE,TSCADJ,BMI1,HLE,AVX2,SMEP,BMI2,ERMS,INVPCID,RT= M,RDSEED,ADX,SMAP> Structured Extended Features2=3D0x4<UMIP> Structured Extended Features3=3D0xac000400<MD_CLEAR,IBPB,STIBP,ARCH_CAP,S= SBD> XSAVE Features=3D0x1<XSAVEOPT> IA32_ARCH_CAPS=3D0x8<SKIP_L1DFL_VME> AMD Extended Feature Extensions ID EBX=3D0x1001000 VT-x: PAT,HLT,MTF,PAUSE,EPT,UG,VPID,VID,PostIntr Hypervisor: Origin =3D "KVMKVMKVM" ... ... <END LAYER 1 - dimes.log>> I also did cpuctl load and here are result from cpucontrol (I am not sure how to interpret these or if provided vectors are still valid with FreeBSD 12.1) <<START CPUCTL>> # kldload cpuctl # cpucontrol -m 0x480 /dev/cpuctl0 MSR 0x480: 0x00d81000 0x11e57ed0 # cpucontrol -m 0x482 /dev/cpuctl0 MSR 0x482: 0xfff9fffe 0x0401e172 # cpucontrol -m 0x48b /dev/cpuctl0 MSR 0x48b: 0x00037bff 0x00000000 # cpucontrol -m 0x48c /dev/cpuctl0 MSR 0x48c: 0x00000f01 0x06334041 <<END CPUCTL>> I also saw that in the original but, it appear that issue was that the bhyve KLM was not loading. I my case the vmm module is loading but I am getting runtime failure... Any tips you can provide to help with diagnosis would be appreciated and I = can chase upstream if needed, if this is KVM regression. Thanks.
