Local Linux User Yells at Kubernetes Networking

I’m at my wits end, Ive been trying to get k8s running inside of virt-manager with a calico overlay with 2 nodes working for 3 weeks now to no avail. Does virt-manager and it’s network interfaces block ipip traffic?

Good chance you’ve already done this but just checking…

Use a “QEMU/KVM” connection for your VMs, not “QEMU/KVM User Session” or they’ll be isolated.

Use a custom network:

  • Edit > Connect Details, Virtual Networks tab
  • Create a network using the defaults (make sure IPv4 range isn’t in use).
  • Apply the network to all VMs.

I’ve never had blocking issues with that setup.
