I can make all configurations in gns3 and save to the startup-config .
 
When I finish any configuratiion and save the project and restart the computer, the config is also seen in the #sh run. And all ok.

But when I switch on the computer in next day and I make #sh run, the running config  and  startup-config  are empty, no config, there is just 
the default running config. And my added  startup-config  in the bootflash: is also rubbed ,no more there.

I downloaded the image and ofcourse has no need for license(s).
 
???????????????????? WHAT  IS THE PROBLEM ??????????????????????????
 
 WMware to Gns3  titanium-d1.5.1.2.gbin          -->  allows to change an interface from L3 to L2, plus allows more but doesnt save.
 
Cisco_NX-OS_Titanium-v6.2.1_Image_for_Virtual_Box_GNS3_6.2.1_Downloadly.ir  --> doesnt save, plus the image does not even allow to change an interface from L3 to L2
using the switchport command. Instead the switch reboots to login:

I kindly ask if you have a booting and saving image  -->  bootflash:/ titanium-d1.5.1.2.gbin or functional  Cisco_NX-OS_Titanium-v6.2.1_Image_for_Virtual_Box_GNS3_6.2.1.
 
Or I kindly ask if you can provide a link to something really functioning. Any nexus on WMware to Gns3 or any nexus in Virtualbox to Gns3.
 
 
Here is the nexus boot sequence:
