Although the guest's CPUID bits can be controlled in a fine grained way in QEMU, a simple way to inject the host CPU is missing. This is handy for KVM desktop virtualization, where one wants the guest to support the full host feature set. Introduce another CPU type called 'host', which will propagate the host's CPUID bits to the guest. Problematic bits can still be turned off by using the existing syntax (-cpu host,-skinit)
kvm already knows how to filter unknown bits to prevent runtime failures. This is even more important for qemu/tcg, since even simple bits which only define new instructions need explicit support in qemu. I think -cpu host should default to filtering unsupported bits instead of hoping the guest will ignore them or expecting the user to know which bits to remove.
