Hello:
I am looking at the RHEL 5.4 virtualization guide. According to Chapter 17, if I want to use KVM on my machine, I need to check if it has the constant Time Stamp Counter by running this:
cat /proc/cpuinfo | grep constant_tsc
When I do that on the server (Currently running CentOS 5.3), I do not get any output. According to the output, that means my system does not have the counter.
It then gives me instructions for AMD revision F CPUs. I did a search and did not find anything that seems relevant to revision F. The only stuff I am finding is talking about socket F. Is that the same things as a Socket F CPU or something different?
Thanks, Neil

For example,
http://www.chiplist.com/AMD_Athlon_64_processor/tree3f-section--2103-/
may help.

I have an Opteron. I don't see a similar listing for those. Do you?

Well, according to CPU info, I have:
vendor_id : AuthenticAMD cpu family : 15 model : 65 model name : Dual-Core AMD Opteron(tm) Processor 2210 stepping : 2 cpu MHz : 1809.490 cache size : 1024 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 2 apicid : 0 fpu : yes fpu_exception : yes cpuid level : 1 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 ht syscall nx mmxext fxsr_opt rdts cp lm 3dnowext 3dnow pni cx16 lahf_lm cmp_legacy svm extapic cr8_legacy bogomips : 3622.54 TLB size : 1024 4K pages clflush size : 64 cache_alignment : 64 address sizes : 40 bits physical, 48 bits virtual power management: ts fid vid ttp tm stc
The closest match in that list is: AMD Opteron DP 2000 series Dual-Core processor (Santa Rosa, Rev. F)
So, I guess my processor is a Rev F processor. I will follow the instructions in the virtualization guide.
Thank you, Neil

No, Rev F is different than Socket F ... you can get a Turion X2 TL for a laptop with socket S1 but still running a Rev F chip
Rev F originally meant the dual core socket F chips built in 90nm but later other chips derived from the opterons but used different sockets kept the rev F...
If you want to know the socket, you can run dmidecode. Look for the processor section and under there Socket Information. Most boards (at least all but one of the ones I'm running right now) provide you a proper socket identifier.
