misc: add checking while append new vm

This patch will add checking cpu affinity while user click to add new vm.
When I was following client's findings up I found that if I click to add
a new post-launched vm for step 3.Configure settings for scenario and launch
scripts, it failed to show error messages. The current version will check cpu
affinity and serial port for post-launched and hv when creating a new vm, it
wont verify when adding new post-launched & pre-launched vms, it will fail to
save scenario configuration file without any explanation. I've rebuilt and run
configurator, confirmed the checking procedure works.
