First

When I create a project and add IOU device in my project, then I see GNS3 will create a directory in path:



But if I open my project with new install GNS3 IOU VM. I get error:



I think GNS3 only create directory device-1, device-2 ... in GNS3 IOU VM when I add IOU device in GNS3. When I open my project GNS3 only check directory (not create). If not found, will get error.

I think when open project if directory not exit, GNS3 need to create directory for free error.


Second

When I install new GNS3 IOU VM with new ip address and add new ip into remote server option and remove old ip address.
Then I open old project with old ip remote server in file ".gns3". GNS3 will add old ip remote server into GNS3 and I get error:



I think when get time out error. GNS3 need connect to other remote server for free error.
