Talos installation

Talos can be installed using two methods:

• Talos install vanilla: provide required siderolink.api link.

• Talos install via Factory image: provide required factoryhash.

In both cases, additional kernel parameters are required. These will override any defaults injected.

Talos default kernel parameters are:

slab_nomerge
pti=on
vga=normal
locale=en_US
console-keymaps-at/keymap=us
net.ifnames=0
panic=0
initrd=initrd.magic
init_on_alloc=1
consoleblank=0
nvme_core.io_timeout=4294967295
nvme_core.multipath=n
printk.devkmsg=on
ima_template=ima-ng
ima_appraise=fix
ima_hash=sha512
talos.platform=metal
talos.events.sink=[fdae:41e4:649b:9303::1]:8091
talos.logging.kernel=tcp://[fdae:41e4:649b:9303::1]:8092

More information about Talos kernel parameters you can find here: https://www.talos.dev/v1.7/reference/kernel/

Network configuration for your server will be automatically injected by our systems.

Classic nic names vs predictable nic names

The kernel parameter net.ifnames=0 will disable predictable network interface names and revert to classic names like eth0, eth1, etc.

This works in most cases where a server only has 1 or 2 uplinks. If you have more than 2 uplinks and network configuration is failing, it can be that Talos is assigning the wrong interfaces to eth0 and / or eth1. In that case you can try using the "predictable interface names" solution, by using the kernel parameter net.ifnames=1.
