Good day,
I have VIRL server running on a VM, but my topology is currently saved on one of the machines that VM Maestro is running on. I would like to run the client from my laptop at home, or desktop at work, etc. Is there a way to move the topologies to the VM running the VIRL server and load/save the topologies from/to the server automatically, so I don't have to try and keep the topologies sync'd across all my client machines?
Thanks in advance!

I was just curious for this is my second year of having a license and I really haven't used it to its potential. It just seems to be a product under constant "re-compile". I was excited about the easier upgrade options in December and 1.x release, I go to 1.0 then 1.0.11 and then in less than a month another 1.x release. Just reading the forum for issues it seems it cannot get to one major release level for users to use it confidently for a period of time without finding a feature(basic ones too) that doesn't work or will be fixed in the next release. It is great to participate in the development and enhancement of the tool but there is too much tweaking churn for prime time use.
I prepped a ASUS ROG laptop with i7, 64 gig ram and SSD to run this and other virtulizaed tools GNS3, Mininet etc. A "LABTOP" if you will that I can bring to my clients to use for network design/planning simulation needs but I cannot use VIRL for this just yet. The progress is great but it needs some additional simplification and stabilization. As I mentioned in other posts and having been a Cisco user vet from IOS 9.x days and this will be a hit if you can automate and hide all this feature fix nonsense and have it done automatically upon each activation so the engineer's can USE the tool. Plus at the same time keep it open if the engineers need to "Bolt on" features from Cisco other Vendofs OS etc.
VIRL should be - simple as a car to drive with an Automatic transmission but also able to be tuned up or "hot rodded" when needed by the individual.

Goal:
Our goal for this is to build a community for those using VIRL for teaching and or academic research and provide a platform for you to share your experiences and ideas, and hopefully this can help cultivate connections and relationships among the community. We hope that besides VIRL the tool, the community and these connections is another resource we can provide to you.
Agenda:
-Overview of VIRL in academia around the world
-Round table introduction (position, institution, and what they are using VIRL for)
-Feedback on VIRL
Attendee:

Hello there guys, and thanks for your support in advance. I'm relatively new at virl and noticed that every time i get a sub interface configured (have core facing sub interface interface and CE facing sub interface as i'm using a virtual switch for physical topology), and i want to run lets say ISIS for the core facing sub interface (which works perfectly fine along with mpls ldp) and ospf as PE to CE protocol on the second sub interface out of the same physical port and ospf never comes up. configuration its pretty basic and it is the same as i have t working (out the physical port) with no issues, and adjacency comes up great.
Are there any support issues for cases like this that you know of? should i always use different interfaces to run both protocols, one for each (which would mean i have to modify the entire topology)?
Thanks again guys!
Have a good one.
Chris!

Hi,
can anyone tell me how I can check my CPU if it supports KVM extentions? I have
a AMD A8-5500 and I would like to use VIRL on a ESXi 6.0. But before I pay 200$
I like to know that VIRL works with my ESXi-Server.
For the future I think I will change the mainbord and CPU because actualy my CPU
has 4 cores and if I have problems with some topology`s, maybe I would buy
a AMD Sockel AM3+ mainbord and a CPU FX-8320 with 8 cores.I hope someone can help me.

We are really excited to announce the availability of VIRL on Packet's bare metal cloud platform. When you need extra resources to spin up large simulations, VIRL on Packet.net is the solution!
Head to http://virl.cisco.com/cloud/ to get started.Packet provides highly competitive hourly rates, fast deployments, and a range of bare metal server configurations to suit your budget. It is an excellent cloud platform for VIRL users.
Before you get started, create an account on packet.net (you will need to provide a valid credit card). Next, make sure that your VIRL server has internet access and has a valid license. Now, be patient as the provisioning process may take up to 30 minutes to complete. So grab some coffee or tea and get ready for VIRL on the cloud!
With out the overhead of nested virtualization, you are now able to take full advantage of all the available hardware resources and create large and dense topologies.
When you're done, terminate your server instance easily with a single command.
Note that your VIRL license node limit will be DOUBLED FOR FREE when you use VIRL on Packet.
Register today and receive $25 usage credit on Packet: https://www.packet.net/promo/virl/
Please note that you need to have a valid VIRL license key to proceed. You can purchase a key on our website: http://virl.cisco.com/getvirl/
Getting started:
If you already have a VIRL instance installed, you can launch directly from your
VIRL server. Read the instructions here to set up your VIRL on Packet server: https://github.com/Snergster/virl_packet/blob/master/salt.README.md
See it done: https://youtu.be/29xvV5VZtqQAlternatively, use the VIRL launcher app with Virtualbox or AppCatalyst to set up your VIRL on Packet server: https://github.com/Snergster/virl_boxcutter/blob/master/README.md

Summary
This post will guide you with steps needed to deploy a cloud instance of VIRL to packet.net. Make sure you have already followed all the pre-requisite steps needed before you attempt to deploy your cloud instance.
For more information please take a look at our announcement thread!Getting started:
Using a licensed VIRL server to deploy a bare-metal instance on Packet
- Run the following commands from your VIRL server
sudo vinstall saltsudo salt-call state.sls virl.terraformcd virl_packet- Log into your packet.net account
- Create an API key
- From your VIRL server edit the
settings.tffile located in/home/virl/virl_packet
sudo nano /home/virl/virl_packet/settings.tf- Edit this section:
variable "packet_api_key" {Replace
description = "get your packet api key at https://app.packet.net/portal#/api-keys"
default = "bad_api_key" <<====
}"bad_api_key"with the API key you created in Packet and save the file
IMPORTANT: make sure to include the '.' in the next two commands. You should still be in/home/virl/virl_packetdirectory. If you are not sure, run this command:pwd- Check your configuration:
terraform plan .- Deploy your server:
terraform apply .
Your bare-metal server will now be provisioned and once the process completes you will be given log in information. This process typically takes about 30 minutes to complete.- If you missed the log in information run this command at anytime to recall it:
terraform showSubsequent launches will only need to follow steps 5 -7
Connecting to your Packet Server:
(See it done -- link coming soon)
Your new bare-metal server is provisioned securely. In order to access your server you will need to establish an OpenVPN tunnel from your computer to your Packet server.Take a look at this post for more detail on installing OpenVPN
- Install the OpenVPN client appropriate for your system.
- You will find the file 'client.ovpn' under
/home/virl/virl_packet- The 'client.ovpn' file can be copied out to other devices, such as a laptop hosting your local VIRL instance.
- Download the file and open it with your OpenVPN client
- Start the tunnel to connect
- Once the tunnel is connected, open a browser to http://172.16.11.254
- If using VM Maestro don't forget to change the connection profile to point to your Packet server; http://172.16.11.254
Terminating your Packet server
When you're ready to terminate your Packet VIRL server, run the following commands from your LOCAL VIRL server:
terraform destroy .Next:
- Log in to the Packet.net portal
- Review the 'Manage' tab to confirm that the server instance has been deleted.
- If necessary, delete the server
- Review the 'SSH Keys' tab and remove any ssh keys that are registered
[NOTE] Your uwmadmin and guest passwords are in
/home/virl/virl_packet/passwords.tffile. You may also recall them by running the commandterraform show.
