[libvirt-users] QEMU cmdline for default -smp reasonable (qemuBuildSmpArgs) ?

Hi! When only the vCPU tag is specified, libvirt by default generates a multi-socket topology(sockets=vCPUs,cores=1,threads=1) for the qemu command line. Is there a specific reason behind choice of this default behavior? Could a default of (socket=1,cores=vCPUs,threads=1) would have been a better choice ? -- Regards, Sanjay
