You can’t run multiple instances of the same VMware VM if you are using VMware Player. If you want a portable topology you will need to use Qemu. This mean a topology using a VMware VM will not be portable on a different computer. The data of the VMware VMs are stored outside GNS3. We are not discussing the importing of the GNS3 VM in this document but rather the addition of other virtual machines to GNS3 topologies which may be running in the GNS3 VM or running locally.
