On version 2.1.12 to enable KVM support option - Enable nested VT-x / AMD - V is not highted to be enabled ? because of it wont support KVM, your view pls ? thanks David.
Always so clear that It is seems easy.thanks
Greatly explained
Will try this installation.
good tutorial sir, Well Done and Thank You!
Amazing content as always.
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
Many thanks for all the help, regards from Manchester
Thank you very much for guiding.
Thank you sir.
Thanks so much for the video
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] "
Awesome David, thank you so much for sharing your knowledge & Happy New Year
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.
thank you bro
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
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.
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?
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
Thanks. This is just another options. Keep on using VMware if you are happy with VMware. Some people don't want to pay for VMware Workstation Pro and some struggle to get VMware Workstation Player working.
Always the best
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?
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 = "
Thank you very much
Thank you for sharing .
Thank you for watching Warren
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.
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
David, you are configurating in console as master!
the file i downloaded from GNS3 site doesnt work it shows as a regular ubuntu VM and doesnt say GNS3 VM
any idea why ?
can i run the virtual part of GNS on a different machine on my network and connect to it form my router?
my KVM switch is still set to fals despite me enabling nested VT-x/AMD
The "Enable Nested VT-x/AMD is greyed outso I can't enable it. I have a Intel processor but I have VT enabled in BIOS because I am already running VIRL in VM workstation. Do you know what may be wrong?
Is your Host Machine running Linux or Windows? Also what processor are you using exactly?
Try completely uninstalling gns3, downloading latest from Oracle, then installing fresh. That fixed it for me.
Excelente video to install GNS3 in VirtualBox but the major factor is PC Processor, in my case, Intel processor doesn't work with the virtual box to the ability KVM support
does vmware free version fix problem?
Hello,
Thank you. I am not able to see anything under VM name in GNS3 for the preferences. I tried refreshing it several times, but I could not find anything. What should I do, please?
cause VirtualBox can not support VIRL images any more, just use Workstation pro or Workstation player
Hi David, I can't enable the Nested VT-x/AMD-V option. Is my computer a Intel CPU?
Hi, have you find out how to fix it? I have the same problem only with virtual box. With VMware, there is no such issue.
@@zakwan3169 No~ I saw the other respond for this issue. The feature is need AMD CPU. I setup KVM option in Virtual box , but still not enable in GNS3 server.
@@youtube-watcher-TW Hi, you may have figured this out by now as your comment was a while ago. I had the same issue and it took me a while to figure out. You need to go into your BIOS (on a desktop just restart and mash the delete key a bunch until the screen comes up, on laptop you can hold the shift key while you press the restart button until the screen goes black), from the BIOS you need to find your virtualisation option. It'll be found in different places on every BIOS so you'll have to feel it out. On my MSI AMD 570x it was labelled as "SVM" for some reason. There may be a search option, I'd recommend just typing the letter V in there and reading the description for everything that comes up. Hope you solved your issue and this little snag didn't set you back too hard!
Hello!
I have a problem : Enable nested VT-x/AMD-v is caching what will i do please ??
Thank you !
I am sorry if I didn't pay attention, but if you don't have AMD processor, but intel instead, what is the solution? Is Qemu able to run IOSv images?
Currently you need to use VMware Workstation Pro or Player (but a lot of people have had issues with Player).
Hi
I did try many times but it does not work and when I open GNS3 preferences , i see there is port 80 in the settenings which is not exist in the videos, pls i need help with this because i can not continue my studying without it.
Can I run this on VMware workstation pro since I don’t have an amd processor
Yes, you could use VMware workstation instead of VirtualBox.
I currently use vmware player, would there be any advantage to changing to virtual box? Thanks for another great video
Thanks. As the saying goes, if it's not broken, don't change it. If you are happy with VMware Player, just use that. However, a lot of people have issues with VMware Player and VIX and some people prefer VirtualBox to VMware Player which is limited.
can we use VirtualBox software to create cisco VMs?
I am getting error GNS3VM: Error while executing VMware command: vmrun has returned an error, any solution ??
I can't activate VT-x/AMD-v nested on the GNS3 VM : I don't know why.
Hello Sir, i have installed GNS3 in virtual box, I want to do FMC , FTD Labs with GNS3, could you please upload these labs
Hey David, tried to enable the Nested VT-x/AMD-V but it was gray even through the machine was off at the time.
I'm using windows 10 Home 64bit and a strong pc if it matters on this case
Would highly appreciate if you would help me on this !
And I do not have an AMD proccesor but rather an I7 what I'm asking is for a different way to overcome this obstecole
Or I'll just have to wait till it'll be enabled by virtual box
As mentioned in the video, VirtualBox doesn't support nested virtualization on Intel processors. You need an AMD processor. You will need to use a VMware product to get nested virtualization or with GNS3 2.2, use Hyper-V
My GNS3 didn't find the VirtualBOX VM.... I've already checked the Windows Firewall.... :(
how to add a server and wireless device?
PSA for anyone who might be having issues with KVM support, my particular issue was resolved after turning off "Virtual Machine Platform" in Windows Features (start button -> Search -> "Turn Windows Features on or off") I'm on a Lenovo Legion 5 15ACH6 running windows 11.
Fantastic, I solve the issue by your method as well!!! Thanks a lot :-)))))
YAAAAAY)))))))))), It worked for me too!!
idk why the guy above me didnt like your comment!
So, that means we don't need to buy cisco routers to practice a real thing?
i want to buy a cpu for virtualazation
What do you recommend Intel I7 or AMD .. What would you buy if it's up to you? I know it depends on many factor but i want to see what would you go with
I primarily use Macs, so I have Intel processors. I'll let someone who is more of a PC person give you recommendations to this question.
go with amd threadripper 1900x
can i run many EVE-NG/GNS3 nodes without lagging? Nodes contain some firewalls with lots of routers and switches @@nikhilt3755
virtualbox slowly in my windows.. huhuhu help me for best setting.
wes ssd kang?
I have tried this on three seperate computers (All intel), Windows 10, Windows 7 and all three computers have and can run Virtual machines, they all have VT-X support enabled in the bios and all three, will not allow KVM support. Why does this not work?
VirtualBox only supports nested virtualization on AMD processors. Intel is not currently supported. Hopefully they will support Intel at some point, but it is not currently :(
@@davidbombal Thus, the early comments on your video, which, I ignored. OK. Well. Time to go dig up some old AMD machine...with Virtual support and try again.
@@paulsccna2964 Yes, unfortunately still the case :( I suggest you do as you say or use VMware Player on your Intel computers and follow this: gns3.com/community/discussion/gns3-with-workstation-player-15-
There's a link to download the Cisco IOS image?
You can get IOS images from virl.cisco.com (you need to pay for a subscription if you don't have one already)
Google is your friend :)))))
VirtualBox 6.1 now has nested virt for Intel processors. If you're like me and the KVM option is still greyed out, follow: stackoverflow.com/questions/54251855/virtualbox-enable-nested-vtx-amd-v-greyed-out
Has anyone ever got this to work in less than 20 hrs?
still cant get gns 3 to work.
this is what i get Failed to open a session for the virtual machine GNS3 VM.
Nonexistent host networking interface, name '' (VERR_INTERNAL_ERROR).
Result Code: NS_ERROR_FAILURE (0x80004005)

First xD
fu this update why fu virtual box it become so complicated why that why
19:21 ah, yeah.. same.
You had the same issue downloading from VIRL? After recording the original video, added this download piece showing the process: 17:43
Too much bullshit to run to Cisco I’ll stick with Citrix NetScaler/Citrix Systems ADC/VPX
