The vendor string should be specific like GenuineIntel or AutheticAMD and not something you invented. (In reply to comment #2) > The vendor string should be specific like GenuineIntel or AutheticAMD and not > something you invented. Hi Dor, I boot the guest without specifying the vendor id, seems the siblings value is still not right. If any wrong, please correct me. Thanks. CLI: /usr/libexec/qemu-kvm -M rhel6.1.0 -enable-kvm -m 4096 -smp 2,cores=4,threads=1,socket=2 -cpu Opteron_G3,-x2apic,+svm -name rhel4.9 ...-boot c -drive file=/mnt/images/RHEL-4.9-32-virtio.qcow2... processor : 0 vendor_id : AuthenticAMD cpu family : 15 model : 6 model name : AMD Opteron 23xx (Gen 3 Class Opteron) stepping : 1 cpu MHz : 2295.061 cache size : 512 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 2 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 5 wp : yes flags : fpu de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht pni syscall nx lm pni popcnt bogomips : 4598.44 processor : 1 vendor_id : AuthenticAMD cpu family : 15 model : 6 model name : AMD Opteron 23xx (Gen 3 Class Opteron) stepping : 1 cpu MHz : 2295.061 cache size : 512 KB physical id : 0 siblings : 2 core id : 1 cpu cores : 2 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 5 wp : yes flags : fpu de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht pni syscall nx lm pni popcnt bogomips : 4857.89 Dor, Boot rhel3.9-32 guest with same cli except the vm image, cat /proc/cpuinfo outputs the correct siblings & cpu cores number in guest. processor : 0 vendor_id : AuthenticAMD cpu family : 15 model : 6 model name : AMD Opteron 23xx (Gen 3 Class Opteron) stepping : 1 cpu MHz : 2293.758 cache size : 512 KB physical id : 0 siblings : 4 core id : 0 cpu cores : 4 runqueue : 0 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 5 wp : yes flags : fpu de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx lm bogomips : 4561.30 processor : 1 vendor_id : AuthenticAMD cpu family : 15 model : 6 model name : AMD Opteron 23xx (Gen 3 Class Opteron) stepping : 1 cpu MHz : 2293.758 cache size : 512 KB physical id : 0 siblings : 4 core id : 1 cpu cores : 4 runqueue : 1 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 5 wp : yes flags : fpu de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx lm bogomips : 4574.41 Seems "physical id" is wrong, too. |
