Using vios-adventerprisek9-m.vmdk.spa.156-2.t in GNS3
Now that you have downloaded and verified the image file, you can import it into GNS3 and use it as a QEMU virtual machine. QEMU is a generic and open source machine emulator and virtualizer that GNS3 supports.
To import the image file into GNS3, follow these steps:
Open GNS3 and go to Edit > Preferences > QEMU > QEMU VMs.
Click on the New button to create a new QEMU VM.
In the Name field, enter a name for your VM, such as Cisco IOSv.
In the Type field, select Default.
In the Qemu binary field, select the appropriate binary for your operating system, such as qemu-system-x86_64w.exe for Windows or /usr/bin/qemu-system-x86_64 for Linux or Mac OS.
In the Disk image (hda) field, browse to the location of your downloaded image file and select it.
In the Ram field, enter 512 MB.
In the Adapters field, enter 4.
In the Adapter type field, select e1000.
In the KVM acceleration field, check the box if your computer supports hardware virtualization. This will improve the performance of your VM.
In the Additionnal settings field, enter -nographic -enable-kvm -cpu host -smp 1 -serial telnet -serial telnet -serial telnet -serial telnet -net none -device e1000,mac=00:00:ab:cd:00:01 -device e1000,mac=00:00:ab:cd:00:02 -device e1000,mac=00:00:ab:cd:00:03 -device e1000,mac=00:00:ab:cd:00:04 -drive file=vios-adventerprisek9-m.vmdk.spa.156-2.t,index=0,media=disk,format=vmdk -boot order=c.

Creating a simple topology using vios-adventerprisek9-m.vmdk.spa.156-2.t in GNS3
To create a simple topology using your VM in GNS3, follow these steps:
Create two instances of your VM by dragging and dropping them from the QEMU section of the Devices toolbar to the GNS3 Workspace. You can rename them as R1 and R2.
Create a connection between the two VMs by clicking on the Add a link button in the Tools toolbar and selecting the Ethernet link. Then click on the first interface of R1 and the first interface of R2.
Create a loopback interface on each VM by right-clicking on them and selecting Add a loopback interface.
Start the two VMs by right-clicking on them and selecting Start.
Open a console for each VM by right-clicking on them and selecting Console. This will open a telnet session to access the CLI of each VM.
Configure basic settings on each VM, such as hostname, interface IP address, routing protocol, etc. For example, you can use the following commands:
R1(config)#hostname R1 R1(config)#interface GigabitEthernet0/0 R1(config-if)#ip address 10.0.0.1 255.255.255.0 R1(config-if)#no shutdown R1(config-if)#interface Loopback0 R1(config-if)#ip address 188.8.131.52 255.255.255.255 R1(config-if)#router ospf 1 R1(config-router)#network 0.0.0.0 255.255.255.255 area 0 R2(config)#hostname R2 R2(config)#interface GigabitEthernet0/0 R2(config-if)#ip address 10.0.0.2 255.255.255.0 R2(config-if)#no shutdown R2(config-if)#interface Loopback0 R2(config-if)#ip address 184.108.40.206 255.255.255.255 R2(config-if)#router ospf 1 R2(config-router)#network 0.0.0.0 255.255.255.255 area 0
Verify the connectivity and functionality of your topology by using commands such as ping, traceroute, show ip route, etc.
