What's not simple about the above 4 options?
What's a better alternative (that insures users understand it and use
it and guest msi and even skype application is happy about it)?
Even if you have -cpu Nehalem, different versions of the KVM kernel
module may additionally filter cpuid flags.
So if you had a 2.6.18 kernel and a 2.6.33 kernel, it may be necessary
to say:
(2.6.33) qemu -cpu Nehalem,-syscall
(2.6.18) qemu -cpu Nehalem
Or let qemu do it automatically for you.
In order to be compatible.
