Re: Emulate Rpi with QEMU fails

[Thomas Schneider]

Hi,

I already considered the host CPU power.
However I have this 
<https://ark.intel.com/content/www/us/en/ark/products/33924/intel-core-2-quad-processor-q9550-12m-cache-2-83-ghz-1333-mhz-fsb.html> 
CPU
Intel Core 2 Quad Q9550 2,83 GHz
and assumed this should be powerful enough for RPi emulation.

But maybe my assumption was too optimistic.
