undoubtedly going to regret asking this, but i installed f12 on a

model name : AMD Turion(tm) 64 X2 Mobile Technology TL-60
stepping : 2

...
flags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca

rdtscp lm 3dnowext 3dnow rep_good extd_apicid pni cx16 lahf_lm
cmp_legacy svm extapic cr8_legacy 3dnowprefetch
the above *seems* to suggest an oddly slow processor (800 MHz), but
the "svm" flag tells me it has AMD H/W virt support, correct?
however, if i pop over to the corresponding(?) AMD page:
http://products.amd.com/en-na/NotebookCPUDetail.aspx?id=18&f1=&f2...
that page suggests that that processor is 2 GHz, but that there is
*no* H/W virt support.
i'm confused. am i just misreading something?
/proc/cpuinfo shows the current clock speed. Many processors,
especially laptops, scale down the speed of idle processors to save
power.
Try running a program that contains a tight infinite loop and see what
happens then.
Not sure about the virtualization part.
