> Since I do not have networking sorted out yet I cannot update win7 pro, and it
might be the updates which are needed for allowing more than two cpus.
hm, brief search on my side resulted in this tip:

----------
Some recommendations (in Windows, make sure you are running as Administrator):
- Run MSConfig -> Change to Boot tab -> Advanced Options -> "Number of
Processors", make sure there is no check mark.
- Delete processor entries listed in Device Manager, then reboot.
-------------
(I don't think BIOS options from this answer really apply directly to qemu case)
also, if win (or some applications inside it) keep crashing with -cpu host, you
can try to reload host (Linux) kvm module with additional option:
"options kvm ignore_msrs=1" line (without quotes) should be added to
/etc/modprobe.d/kvm.conf
