cpuMhz of virNodeGetInfo() should return maximum cpu frequency.
(See.
http://fossplanet.com/f13/%5Blibvirt%5D-%5Brfd%5D-add-modify-some-api-fun...)
virNodeGetInfo() gets it from "cpu MHz" of /proc/cpuinfo,
but this value is scaled by cpu power saving feature.
This patch gets from
/sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq, if exist.
And if this file doesn't exist, it gets from /proc/cpuinfo.

I think it divide by 1000 is collect, because my machine returns below values.

If not or I'm misunderstanding something, please let me know.
I think we should round up in case we request something, because then
we get at least what we requested. If we truncate a request we might
get less than we requested, this might result in a bad situation.
Recently we switched from truncation to rounding up for memory and
storage request because of this.
But here we are reporting something. In that case we should truncate,
because if we would round up we could report more than there actually
is, this might result in a bad situation too.
So with rounding up request and truncating reports we are on the safe
side in both cases.

I agree with you.
In this case we are reporting cpu MHz, so we should truncate it.
Eric, what do you think?

Truncation works for me. I think these patches have missed the cutoff
for 0.8.8, though, so I haven't looked closely at them yet.
