[kwlug-disc] QEMU vs VirtualBox -- which is faster?

[William Park]

I asked Google AI, and it gave me the following answers:

    time echo "scale=7000; 4*a(1)" | bc -l
    time dd if=/dev/zero bs=1M count=4096 2>/dev/null | sha256sum

Both gave almost identical results for both QEMU and VirtualBox. Granted 
that they are pure "cpu", but I just want to compare.  Man, AI is good!

Kernel compile is more comprehensive (cpu, ram, disk), but it takes too 
long, and lot of things will skew the result.
