Hi, David .

As per your instruction in Video series of Network automation, the 1st video you have instructed how to configuration of loopback interface 0 and ip of that interface with the help of Network Automation tool available in GNS3 market place.
I've exactly carbon-copy of your instruction and implemented on my lab environment.
I've a question, why I am not able to ping 8.8.8.8 from my Automation System, you can find that topology diagram in gns3 community
discussion with the subject of "issue in ping response"
please help me out.

Thanks a lot David, I use my mac and learn Linux with your course `Linux for network engineers` but there is no VMware Player for OS X so I've downloaded the VirtualBox and now I'm trying to configure all these stuffs

[ydda]

Many thanks for all the help, regards from Manchester

Thank you very much, David ... could I ask you about something, I faced a strange issue while opening a console for NX-OSv on GNS3, and it couldn't start and booted a lot for many times, it gave me this message " BUG: soft lockup - CPU#0 stuck for 11s! [insmod:217] "

[belaynehteshome]

thank you for all your helpful tutorials. I am working my thesis on integrating MPLS with SDN, and I tried to connect minininet VM with two router in wmware workstation
, but routers cannot communicate with mininet hosts so, could you suggest me the solution please?

[lemurdog]

My one always fails to import the ova and tried I redownloading the ova, and closing the instance but nope. Maybe vmware player works idk

[subhuman]

very well explained you made it look so easy. I will try this though i have never been a fan of Virtual box i prefer Vmware

[xtensionxward]

the file i downloaded from GNS3 site doesnt work it shows as a regular ubuntu VM and doesnt say GNS3 VM
any idea why ?

[isumitd]

Idk what to do bc I also have AMD processor dual core with 1.5 speed and have a vm running on it.already. Will it be critical to run gns3 as VM.

[sidewickx]

my KVM switch is still set to fals despite me enabling nested VT-x/AMD

[mike-fhhi]

i did the same process and i followed the instruction but my gns3 said ' The NPF or NPCAP service is not installed, please install Winpcap or Npcap and reboot.
'... any idea.? i installed those with cmd admin but every time i opened is the same. advice?

[rackeysingh]

can i run the virtual part of GNS on a different machine on my network and connect to it form my router?

[pradeepikatarun]

Hi,
I am asked to see the performance of different TCP variants -Tahoe, Reno, New-reno and SACK TCP in a network simulator.This i have to show by dropping 1, 2 and 3 packets.Can you please help me how can i do that by using GNS3 simulator.

[skeetabomb]

GNS3 can't start VirtualBox unless the VM has a host-only adapter configured and that adapter has DHCP enabled. In VirtualBox 6.0, go "File > Host Network Manager > Create" - tick the DHCP checkbox. Click "OK". Once this exists, select the GNS3 VM, then go "Machine > Settings > Network > Adapter N(e.g. 2) > Attached to = Host-only > Name = <the adapter you created above>"

Enable Nested Virtualization In VirtualBox
Starting from version 6.1, Oracle VirtualBox supports nested virtualization feature on host systems that run AMD and Intel CPUs. So make sure you have running the latest virtualbox version
