what is the recommended value for nx (and why)?
Enabled (so you get no-execute memory protection).
do you have a guideline which flags should be identical to ensure
proper live migration?
i would like to do an automatic compare before life migration to
avoid crashes.
All of them [1]. If you have an asymmetric machine, you can disable
those flags with the -cpu switch.
Note the default qemu cpu disables many flags, so if one machine has
sse4.2 and the other doesn't, migration will still work without
disabling anything.
which cpu model do you suggest for 4 core xeon cpus? -cpu host ?
how important is the match of the virtualization extensions?
thanks,

[1] Rather, all flags understood by qemu and kvm that are enabled by
the cpu model that you gave to qemu with -cpu.
