Could not find the default VM directory with VMware player Ī limitation of the free version of VMware player doesn’t allow you to change the default VM directory for third parties applications.Įditing the file %Appdata%\VMware\preferences.ini Depending on how you administrate the ESXi it could be a checkbox in your interface or a configuration file to change. In order to use KVM (hardware acceleration for Qemu VMS) you need to enable the nested virtualization on the GNS3 VM in ESXi. For ESXi it’s require manual operation (see below).The hardware virtualization is not enabled for this VM in VMware.The virtualization instructions are not enabled in your BIOS.Your CPU doesn’t support virtualization.VirtualBox doesn’t support it you can’t enable it.The virtualisation software where the GNS3 VM is running doesn’t support nested virtualization. NAT is not supported, use a VPN like OpenVPN instead GNS3 VM KVM support available : false ![]() SSH tunnel is not supported, use a VPN like OpenVPN instead When I connect to a server behind a nat link is not working When I use a SSH tunnel link is not working This mean both server need to be able to communicate directly on this ports check your firewall rules.

VirtualBox.exe is the VirtualBox executable, VBoxManage is the application from VirtualBox for controlling VirtualBox it’s two different executables. In the GNS3 settings the path for your VBoxManage is incorrect. VirtualBox Invalid VBoxManage executable name VirtualBox.exe This problem doesn’t occur with the paid version of VMware because a central database is available to third parties applications. The player version of VMware have limitation and if your VM are not in the default directory sometimes GNS3 could not found the VM.
