IPv6 configuration is being discussed with Sonic net admins.
IPv6 configuration is a bit weird.
* Public block: 2001:5a8:601:f::/64
* Sonic gateway: 2001:5a8:5:3a::15:0/127
* Transport IP: 2001:5a8:5:3a::15:1/127
The gateway is configured to route all traffic for our netblock to the transport IP, which is currently assigned to bender.

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

== Virtualization ==
Virtual machines are KVM guests managed with libvirt.
=== Storage ===
All virtual disks come from a pool backed by the main LVM VG:
virsh # pool-define-as nvme-pool logical --source-name nvme-pool
Pool nvme-pool defined
virsh # pool-start nvme-pool
Pool nvme-pool started
virsh # pool-autostart nvme-pool
Pool nvme-pool marked as autostarted
virsh # pool-info nvme-pool
Name: nvme-pool
UUID: 5812819f-b8bf-484e-98fb-2e100fe83df2
State: running
Persistent: yes
Autostart: yes
Capacity: 1.64 TiB
Allocation: 250.00 GiB
Available: 1.40 TiB
Disks assigned to VMs will appear here:
virsh # vol-list nvme-pool
Name Path
-----------------------------------------
aslo1-root /dev/nvme-pool/aslo1-root
aslo1-srv /dev/nvme-pool/aslo1-srv
backup /dev/nvme-pool/backup
Disks can be created, listed and deleted using the vol-* commands:
virsh # vol-create-as nvme-pool testvm-root 20G
Vol testvm-root created
virsh # vol-info testvm-root --pool nvme-pool
Name: testvm-root
Type: block
Capacity: 20.00 GiB
Allocation: 20.00 GiB
virsh # vol-delete testvm-root --pool nvme-pool
Vol testvm-root deleted
Please avoid allocating large VM volumes as image file within the host's root filesystem: they're slow and hard to manage. It's ok to use images for test VMs.
