Hi,
I'm running CentOS 5.5 (on ThinkPad x61). I use KVM to run a SLES 11.0 (32bits, kernel 2.6.27.19-5-pae) guest. The "cat /proc/cpuinfo" got the result:
processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 6 model name : QEMU Virtual CPU version 0.9.1 stepping : 3 cpu MHz : 0.000 cache size : 32 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 4 wp : yes flags : fpu de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 syscall nx lm up pni bogomips : 1437.69 clflush size : 64 power management:
The CPU Mhz is 0 !!!!
On dom0 (CentOS 5.5), the "cat /proc/cpuinfo" got:
processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 23 model name : Intel(R) Core(TM)2 Duo CPU T8100 @ 2.10GHz stepping : 6 cpu MHz : 2094.743 cache size : 3072 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 2 apicid : 0 fpu : yes fpu_exception : yes cpuid level : 10 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm syscall nx lm constant_tsc ida pni monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr sse4_1 lahf_lm bogomips : 4189.48 clflush size : 64 cache_alignment : 64 address sizes : 36 bits physical, 48 bits virtual power management:

I have another Thinkpad x201i which also use CentOS 5.5 to host SLES11 guest and that machine does not has this problem.
Does anyone know what's wrong ? Can change CPU info of guest OS ? Thanks

Strange ... but reboot dom0 seems fix the issue.
