Bender and Papert are two twin KVM hosts bought by Sugar Labs in 2021.


Network configuration

Network configuration is managed via netplan. To modify, do:

vi /etc/netplan/bender.yaml
netplan generate
netplan apply

Bender is globally accessible through a public, static IPv4 address. IPv6 configuration is being discussed with Sonic net admins.

The br0 bridge is created libvirt on startup with /etc/libvirt/qemu/networks/default.xml. This is a NAT interface and is not meant for VMs directly

Guests simply need to be configured to accept IPv6 routing advertisements. The DNS must be assigned manually.
