[fedora-virt] processor topology?

[Tom Horsley]

Continuing my efforts to prepare for a Windows 7 KVM
install, I've found that Win 7 (Home) won't talk multi-socket
CPUs, it only wants multi-core CPUs, but experimenting
with the Processor settings in virt-manager, if I tell
it to copy my host cpu configuration, I wind up with
a single processor inside the virtual machine.

If I disable that, and explicitly set the topology
to 1 socket, 4 cores (which is what I have), I then
get qemu errors about the host not having the required
features rtm hle x2apic.

So am I basically doomed to have a single CPU windows 7
virtual machine?

(My host is a Intel(R) Core(TM) i7-4770K which is, I believe,
a Haswell chip).

The Haswells are pretty darn new - what chips have the
rtm, hle, and x2apic features qemu wants?
