Try the following command line (on both hosts)
qemu -cpu phenom,vendor=AuthenticAMD
Note that 32-on-64 applications will suffer a performance penalty when using

To be honest, I put this in kvm-specific code because vl.c doesn't have

strtosz() is much too general. We could do it in vl.c without trouble.
However, it takes away our ability to emulate a 640k should be enough

The -numa option to qemu is used to create [fake] numa nodes
and expose them to the guest OS instance.
There are a couple of issues with the -numa option:
a) Max VCPU's that can be specified for a guest while using
the qemu's -numa option is 64. Due to a typecasting issue
when the number
