how can i get cpu information in a guest-linux-system?

[iiiyyyhhhsss]

I can get cpu information by using the command "dmidecode" in a host-linux-system.

But, I failure in a guest-linux-system.

who can tell me how?

[Perryg]

dmidecode runs as su or sudo and works the same on a guest as it does on a host.
Are you sure that the Linux OS you are trying to use this on has it installed?

Yes,i has "dmidecode" installed, and i use "dmidecode" as su...

And I can't get cpu-information but bios-information,,,,,what i can get is :

As you can see,I can't get anything about cpu-information.

[Perryg]

More than likely the reason is due to it being a virtual processor.
If you want to see the CPU info with flags you need to run

Code: Select all

cat /proc/cpuinfo

[iiiyyyhhhsss]

thak you.
actually what i want to get is cpuid.

But, i can't get cpuid by using "cat /proc/cpuinfo".

cat /proc/cpuinfo

In a host os ,I can get ID-Information :

[root@people-earth people]# dmidecode -t processor
# dmidecode 2.10
SMBIOS 2.5 present.

Handle 0x0004, DMI type 4, 40 bytes

But, in a guest os,
"dmidecode" show nothing about ID-Information,
so does "cat /proc/cpuinfo".
