Today finally I have managed to get a very basic cumulus setup<\/a>. It is annoying because I tried several months ago and found some issues with libvirt (and I opened a ticket but didnt follow up) and gave up.<\/p>\n\n\n\n

Now it works. I just want to use KVM-QEMU and Vagrant, that I have already installed in my system. So based on the link, I just created a folder and copied the vagrant file. Then “vagrant up” and wait.<\/p>\n\n\n\n

So I am happy because now I have something to play with and try to build an MPLS lab with cumulus. At some point I would like to try some quaga\/frr lab.<\/p>\n\n\n\n
I am pretty sure that in the past, I didnt have to type my password every single time I run a vagrant command…. <\/p>\n\n\n\n
Ok, we can shutdown the VMs and start the work for the next time:<\/p>\n\n\n\n
