Lab 2.2: Error with namespaces

magnezone150

I have Arch Linux running KVM VMs and as the Lab 1.1 asked for I created an Ubuntu Server VM and all other labs are working so far. Wondering if this is just a networking issue with KVM/QEMU or is there more to it than that?!

sudo ip netns exec namespace1 ip addr add 192.168.1.1/24 devveth1
Error: either "local" is duplicate, or "devveth1" is a garbage.

As Discussed with @chrispokorni, I'll try to run this Lab again via Virtual Box on one of my KVM VMs to see I experience the same issue.
